A flaw in Git can let a malicious repository run an attacker's code on a computer that clones it recursively, together with its submodules. The Git project fixed it this week in Git 2.56.1, with matching fixes for the 2.50 through 2.55 series in 2.50.2, 2.51.3, 2.52.1, 2.53.1, 2.54.1 and 2.55.1. The flaw, tracked as CVE-2026-111760 , is an integer truncation in how Git handles its index. An extremely long path in a repository can pass Git's safety check, but Git then writes it to disk under a shorter name that an attacker can set to .git. This lets an attacker replace a submodule's .git file with a symbolic link to a folder holding malicious hooks or configuration. Hooks are programs Git runs at set points, so once Git uses that folder, the attacker's code can run. Submodules matter here because Git refuses to replace a .git folder with a symbolic link, but in a freshly cloned submodule, .git is a file. The fixed versions, listed in the Git pr...

An attacker exploited a remote code execution flaw in SGLang , an open-source inference engine, and ran code on one of NEAR AI's inference servers last Sunday. The attacker could also have seen requests being processed on that server that day, including requests sent in confidential mode, the company said earlier this week. That mode processes requests inside a trusted execution environment (TEE) designed to keep them private even from the company itself. But the TEE "does not protect against a vulnerability in the software running inside the environment," the company said. SGLang runs inside the TEE, which is how the attacker could reach requests there. That access has since been closed, but not before the attacker moved further into the company's systems. The attacker reached an internal system behind Private Chat, a product the company had already deprecated. So far, the company has confirmed that the attacker downloaded account details for about 100 users...

French software company Vates VMS has warned of a critical security vulnerability in Xen Orchestra that it said is being actively exploited in the wild. The authentication bypass flaw, which does not yet have a CVE identifier, is tracked as VSA-2026-062 . "REST cookie parsing turns authenticationToken=j:%7B%7D into {}," Vates VMS said in an alert. "REST authentication passes that object to the XO token provider without requiring a string." "The token collection treats {} as an unfiltered lookup and returns its first token; the provider authenticates as that token's owner if it is unexpired. The authenticated /rest/v0/users/me/authentication_tokens route then returns reusable login token IDs." In other words, the vulnerability can allow an attacker to bypass authentication by sending a specially crafted cookie and perform arbitrary actions with "Admin" privileges, ultimately resulting in arbitrary code execution on managed pools and ...

Cybersecurity researchers have disclosed details of an attack that exploited two now-patched vulnerabilities in AhsayCBS to deliver a Python-based implant. The activity, observed by Huntress in early October 2026, involves the exploitation of a chain comprising CVE-2026-105133 and CVE-2026-105134 to bypass authentication and execute arbitrary commands on affected systems. Patches for the two vulnerabilities were released by Ahsay Backup in mid-October 2026. The two vulnerabilities are assessed to have been weaponized as zero-days, with the managed security platform first observing threat actors employing a smash-and-grab approach to deploy web shells and XMRig cryptocurrency miners on compromised systems. "However, this incident reflects a much larger intrusion with more patience; the operator planted shells in several places, ran two different miners, staged tunneling tools, and installed a custom implant, all on servers whose job is to hold backups," Huntress rese...

An iOS sandbox escape published on GitHub lets an app read other apps' files on iPhones running iOS 26 and 27. That puts seed phrases, private keys, and login credentials at risk of exposure to malicious apps, Binance warned today. Apple's updates for iOS 26 and 27, released yesterday, do not list a fix. A researcher who goes by forcequit ,  in collaboration with 0xjohnny ,   released the escape, called worse_query , on Sunday, a day before those updates came out. Neither the exchange nor the researcher reported any attacks or thefts involving it. The exchange told users to delete apps installed from untrusted sources, such as sideloaded or manually signed apps, and to update iOS and all their apps. No fix for the escape has been confirmed. For anyone who suspects a breach, the exchange's  security warning  advises moving funds to a new wallet created on a clean device and resetting all active login sessions. The researcher's  proof-of-concept cod...

An iMessage flaw could let a remote attacker join a group chat and receive its messages, Apple said yesterday, and it released updates to fix it. The updates also fix a separate iMessage flaw that could let someone added to a group access messages sent before they joined. As of today, other updates released yesterday for the iPhone XS, XS Max and XR, the iPad (7th generation) and some Apple Watch models do not list either fix. The company's notes also do not say whether either flaw has been exploited, what an attacker would need, whether group members would see someone who joined this way, or whether every member must update to be protected. The updates that fix the iMessage flaws also fix a flaw in Google's Brotli compression library. The notes do not mention any attacks using that flaw. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added it to its Known Exploited Vulnerabilities catalog on October 27. The flaw that could let a remote attacker join ...

Four flaws that attackers could exploit without logging in were fixed today as part of SAP's monthly Security Patch Day—the vendor rates all four 10.0, the maximum CVSS score. Three are in the SAP NetWeaver application server, the software SAP systems run on, and one is in the Web Dispatcher, which receives web requests from the internet and passes them on to that server. The flaws in the Web Dispatcher and the Internet Communication Manager (ICM), which handles the server's web traffic, could allow an attacker who can reach the software over the network to run code, the vendor says. The flaw in the server's SAML 2.0 service provider, which hands off user sign-in to an identity provider, could allow an attacker to log in as any user on some systems that use SAML single sign-on. The flaw in SAP Gateway, which connects the server to other SAP systems and programs, could allow an attacker to impersonate one of the system's own servers and take unauthorized actions...

Anthropic on Monday released Claude Fable 5.2 and Claude Mythos 5.2 models, which it said exhibit improvements in coding, reasoning, and vision. During pre-release training, the large language models (LLMs) helped its engineers "complete otherwise-infeasible software migrations, designed three working electronic devices from scratch, solved two open problems in the physics of black holes, made substantial progress on robotics evaluations, and formalized the proof of Fermat’s Last Theorem in 30 hours." The artificial intelligence (AI) company said high-stakes risks arising from misalignment remain low, and claimed the models matched or performed better than Claude Opus 5.5, Claude Sonnet 5.5, and Claude Mythos 5.1 on most alignment measures, resistance to misuse, honesty, and factuality. "It was roughly an order of magnitude less likely than Opus 5.5 and Sonnet 5.5 to publish harmful content to public package registries without encouragement, though it still did...

Google on Monday released updates to patch nine security vulnerabilities, including one that has come under active exploitation in the wild. The high-severity vulnerability, assigned the CVE identifier CVE-2026-125350 (CVSS score: N/A), has been described as a use-after-free bug in the XML component. Use-after-free bugs typically occur when a program attempts to access a memory location after it has already been freed. Successful exploitation of these vulnerabilities could allow an attacker to achieve data corruption, program crashes, or arbitrary code execution. An anonymous security researcher has been credited with discovering and reporting the flaw on November 6, 2026. Google acknowledged it is "aware that an exploit for CVE-2026-125350 exists in the wild," but has not revealed any additional specific information related to how it's being abused in real-world attacks or who is behind them. "Access to bug details and links may be kept restricted until...

N-able said it has taken N-central Hosted Environments offline and is urging on-premises customers to shut down their servers until further notice following the public disclosure of over 30 vulnerabilities collectively tracked as Able2Shell . "As a precautionary measure, we are temporarily taking our Hosted N-central environment offline while we take the necessary actions to secure the environment and implement appropriate remediation," N-able said . "During this time, customers will be unable to access their Hosted N-central classic environment, and associated services may be unavailable. However, the Ecoverse services under N-able Login remain available and online, including Asset View, Patching, Vulnerability Management, scripting, policies and tagging." The company also said it has not observed any signs of active exploitation of these vulnerabilities, adding it's currently working on a hot fix to address them. The following services are impacted -...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added four security flaws impacting GPUStack, SignalWire FreeSwitch, OpenBSD OpenSSH, and IBM Aspera Faspex to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerabilities are listed below - CVE-2026-123218 (CVSS score: 9.8) - An incorrect authorization vulnerability in IBM Aspera Faspex that could allow an authenticated user to craft a specific message to bypass authorization, causing privilege escalations. (Fixed in November 2026) CVE-2026-116779 (CVSS score: 9.8) - A code injection vulnerability in SignalWire FreeSwitch that could result in configuration and credential disclosure, arbitrary call control, and command execution. (Fixed in October 2026) CVE-2026-123158 aka SSHole (CVSS score: 8.1) - An unexpected status code or return value vulnerability in OpenBSD OpenSSH on Linux that could allow for authentication bypass. (Fixed in November...

A system doesn't always need a complicated bug to let someone in. Sometimes, a blank password is enough. That's one of the bigger stories this week. And it gets worse when the tools meant to keep systems updated or running safely become part of the attack. Elsewhere, attackers are hiding inside normal web traffic, stealing credentials from network devices, and finding new uses for exposed systems. AI is helping some of them move faster, but old mistakes are doing plenty of the work too. Even forgotten settings and small changes made months ago are coming back to cause trouble. There's a lot packed into this week's news, including some strange research findings, fresh attacks, and a few warnings worth taking seriously. Here's the full recap. ⚡ Threat of the Week OpenSSH Flaw Sees Exploitation Attempts — Threat actors are attempting to exploit a recently disclosed security flaw impacting OpenSSH that can enable sign-ins to accounts that have no password set....

The login systems behind two car brands' mobile apps could be taken over completely, two security researchers found, allowing them to access any customer's account and, for an owner with a connected car, unlock the doors and start the engine. Both apps signed customers in through ForgeRock , an identity platform now part of Ping Identity , and on those servers the researchers reached an administrator console that still used its default password. They tested the full attack only on their own and consenting owners' cars in the United States, in February 2026, and both systems were fixed about two hours after they reported the problem. Shubham Shah and Sam Curry published their work late last week. They had started with the apps: both brands signed customers in through the same platform, which runs in two parts: one for login and one, called OpenIDM , that holds customer records. OpenIDM comes with a built-in administrator console powered by the Apache Felix tool. For...

Some people who set up a Keplr crypto wallet with their Google or Apple account have had money stolen by an attacker. Keplr uses a company called Web3Auth to run that Google and Apple sign-in. The attacker used a security flaw at that company to reach the wallets, both companies said late last week. Web3Auth then used the attacker's own route to empty other at-risk wallets before the attacker got to them, it said. It moved that money, with help from the wallet maker, into recovery wallets for safekeeping. So an empty balance may mean the money was rescued, not stolen. Wallets made with a recovery phrase (a backup list of 12 or 24 words) or a hardware wallet are not affected, the wallet maker said. It has paused Google and Apple sign-in while it investigates. What Affected Users Should Do The wallet maker has given this  user guidance  for accounts created with Google or Apple login: Do not send new funds to the account. Do not re-import the account or recr...

Everyone running LNbits , a free, open-source Bitcoin Lightning wallet system, should shut down their servers now because of a wave of attacks, the project said yesterday. It has several security fixes to release and asked operators to be careful until they are out. One operator said new accounts used an exploit to withdraw 2,285,545 satoshis, about 0.023 bitcoin, from his server before he could stop it. The shutdown notice came about 80 minutes after a first, narrower warning. That warning asked operators to disable Paywall, an add-on that makes people pay to view content, while the project looked into a possible bug. As of 09:00 UTC today, the project had not released a fixed version. On X, it had not canceled the notice, offered another option, or told operators how to check whether their servers were hit before they were shut down. Ben Arc, an LNbits developer, said in a  patch estimate  yesterday that patches "should be merged and available within 24-48hrs." Cou...

A single attacker using AI agents pulled emergency dispatch records covering seven Taipei districts, researchers at Acronis's Threat Research Unit said last week. The agents also found a Taipei fire department platform exposing patient data from 2018, including ECG readings and ambulance video footage, without a login. The researchers are highly confident that the attacker is a single person based in Hualien City, Taiwan. He aimed the agents at hundreds of organizations in at least 11 countries, including emergency services, banks, universities and military systems. The agents collected data or accessed systems at about 10 of them in Taiwan, Mexico and Thailand. The evidence comes from the attacker's own server, which initially appeared to be a misconfigured development system. It turned out to be his operational attack platform, containing more than 90,000 files, including the agents' conversations, his command history, hacking tools, credentials, and victims' d...

U.S. government agencies have warned that threat actors are actively targeting industrial refrigeration and cold-chain monitoring systems globally with an aim to cause service disruptions, fire hazards, and loss of inventory. "The actors may exploit vulnerabilities or weaknesses in unpatched or internet-accessible controllers to remotely alter settings and force units into continuous heating and defrost cycles, which can cause widespread inventory loss and equipment hazards," according to a joint advisory. According to the U.S. Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Health and Human Services (HHS), Department of Agriculture (USDA), and Department of Transportation (DOT), threat actors are likely to exploit authentication bypasses, arbitrary code injection, and weak configurations to gain access to these systems and cause the following effects - Change of temperature, which, in turn, could affect the service l...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a high-severity vulnerability impacting SonicWall SonicOS to its Known Exploited Vulnerabilities ( KEV ) catalog, following reports that it said may have been exploited in real-world attacks. The vulnerability, tracked as CVE-2026-19868 (CVSS score: 7.1 / 7.5), has been described as an authentication reinforcement vulnerability via alternate authentication methods. "An authentication enforcement vulnerability in SonicOS SSL-VPN service may allow a user with valid credentials for an alternate authentication method to bypass SAML authentication controls. Successful exploitation may also bypass SAML-enforced multi-factor authentication (MFA)," SonicWall said in a Friday advisory. The company also acknowledged that it "investigated a report indicating potential exploitation of this vulnerability," urging customers to update to the latest version as soon as possible. SonicWall did not di...

Some WordPress sites can still be attacked while they install the fix for an actively exploited flaw, according to Umut Bayram, the Picus Security researcher who found it. The update that installs the fix still unpacks its files using the site's old, unpatched code, so an attacker who strikes at the right moment can run code on the server. The researcher advises blocking web access to the site's wp-content/upgrade folder before updating. The flaw, tracked as CVE-2026-119977 , affects WordPress 4.7 through 7.1.3. During a core update that uses a complete package, WordPress unpacks a copy of the new version into a temporary folder inside wp-content/upgrade. That copy includes the WordPress installer, and the web server can usually reach it. An attacker with no account who can determine the folder's name and access the installer before WordPress deletes the copy can end up running code on the server. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) ad...

Threat actors are attempting to exploit a recently disclosed security flaw impacting OpenSSH that can enable sign-ins to accounts that have no password set, according to Previdian . The vulnerability, tracked as CVE-2026-123158 (CVSS score: 8.1) and codenamed SSHole (or *sshole), impacts Linux systems that run OpenSSH on the musl C library with Pluggable Authentication Modules (PAM) disabled, including Alpine Linux's default OpenSSH server configuration. An unauthenticated attacker can supply an oversized password to access accounts that are deliberately configured without usable passwords, without having to steal credentials or SSH keys. The issue, discovered by security researcher Ozgun Kultekin, has been addressed in OpenSSH 10.6p2 . The underlying issue dates back to a patch introduced in 2016 to fix a username enumeration vulnerability tracked as CVE-2016-6210 . Under specific conditions, the password-handling behavior in OpenSSH mistakenly interprets a failed pas...
