Starting Tuesday, an attacker used stolen credentials for 4,837 GitHub accounts to plant a secret stealer in repositories those accounts could write to, according to Aikido Security, a security software company. The stealer is built to take the secrets and cloud credentials that a repository's CI workflows can reach. It ran in at least 1,806 repositories, where the attacker has likely collected those credentials, the company says. Each attack started with a pull request titled docs: dependency audit notes, opened from a branch named wfx-docs to test whether the account could write to the repository. These test pull requests were opened in 61,764 repositories, and the stealer followed in some of them. In a separate analysis , researchers at SafeDep, which sells software supply chain security tools, counted 8,093 repositories that received malicious commits between 12:46 UTC on Tuesday and 04:36 UTC today. That count covers every repository that received malicious commits, no...

A critical flaw in Apache HTTP Server's HTTP/2 module, mod_http2 , can let a remote attacker run code on the server. Tracked as CVE-2026-119618 , it affects versions 2.4.55 through 2.4.70 and is fixed in version 2.4.71, released yesterday. Only servers with HTTP/2 enabled are affected, according to Red Hat, which ships the server as part of Red Hat Enterprise Linux. An attacker who can reach the server needs no authentication to exploit the flaw and could take full control of the server process, the Linux vendor says. It rates the flaw 9.8 out of 10 on the CVSS scale. The vendor's assessment, published yesterday, also says "public research has demonstrated a reliable exploit" against a server in its default configuration with mod_http2 enabled. It does not name or link that research. Security company Wiz said later that day that no exploit was available and that no exploitation in the wild had been reported. HTTP/2 runs only where the Protocols directive turn...

ConnectWise has taken the precautionary step of disabling five third-party extensions in partner environments following reports of unauthorized access . In an advisory posted on its site, the company said there is no evidence that the incident involves a compromise of its infrastructure or a vulnerability in the ScreenConnect software. "Our initial assessment suggests the activity may involve a threat actor's abuse of independent third-party extensions installed in partner environments," it said . "We are continuing to validate this assessment. The initial access method and full scope remain under investigation." ConnectWise has identified about 400 partner environments with at least one of the third-party extensions installed. It also emphasized that the presence of the extensions alone does not indicate or establish compromise. While these extensions provide an API capable of executing remote commands, access to that API is secured by a passphrase c...

Zoom has released software updates to address two security flaws impacting Zoom Workplace for Windows, including a critical bug that could result in privilege escalation on affected systems. The vulnerabilities are listed below - CVE-2026-108186 (CVSS score: 9.6) - An improper input validation vulnerability that could allow an unauthenticated user to conduct an escalation of privilege via network access. CVE-2026-108187 (CVSS score: 8.1) - An origin validation vulnerability that could allow an unauthenticated user to conduct an escalation of privilege via network access. Successful exploitation of either of the shortcomings could permit remote attackers to escalate privileges without requiring any special permissions or access. While CVE-2026-108187 affects Zoom Workplace for Windows before version 7.1.5, CVE-2026-108186 impacts versions starting from 7.1.0 and before 7.1.8. Earlier this July, the popular videoconferencing platform shipped fixes for another improper ...

Cybersecurity researchers have disclosed details of a campaign in which an emerging agentic penetration testing platform called AntiFox has been used to steal Amazon Web Services (AWS) credentials and pivot laterally into compromised environments. "In several recently observed intrusions, Alibaba Cloud systems hosting AntiFox interfaces were associated with confirmed malicious actions against internet-facing web services and associated AWS environments," Arctic Wolf Labs said in a report shared with The Hacker News. The activity has been observed chaining together web exploitation and web shell deployment to facilitate configuration discovery, credential validation, cloud-service enumeration, secret access, and storage operations. AntiFox, available for download from GitHub, has been described as an artificial intelligence (AI)-driven autonomous penetration testing platform that's built atop the "solid foundation" of ARTEX . As of writing, the project...

Threat actors have been observed targeting Qlik Sense servers to unsuccessfully deliver PowerShell reverse shell commands against multiple environments in October 2026. Cynet's CyOps and Research teams said they identified the suspicious activity in October 2026 against several E.U.-based customers within a narrow window of just over three minutes. The activity has been found to share some level of overlap with a November 2023 campaign documented by Arctic Wolf in which threat actors linked to the CACTUS ransomware operation likely weaponized then-newly-disclosed flaws in Qlik Sense to obtain initial access to target environments. The vulnerabilities in question, which were patched by Qlik Sense in August and September 2023, impact Qlik Sense Enterprise for Windows -

Of the 37,571 Grok-built apps that security company Claroc found online, 35,578 were open to anyone without a sign-in, the researchers said yesterday. They included 24 apps built by staff at the social network X and at SpaceXSI, the company that makes the Grok AI assistant. Most of the open apps were games, landing pages, and calculators, but about 1 in 10 contained internal business or personal data. The staff apps included a confidential onboarding plan for a new sales hire, a sales territory map of 594 accounts, and an X advertising proposal to a U.S. federal agency marked confidential. SpaceXSI, formerly known as xAI, has since taken down all 24 staff apps but not other users' apps, the researchers said. Besides those staff apps, the open apps contained internal data from 30 other organizations the researchers could identify, across fields ranging from construction and energy to healthcare and defense. Of those, 26 have more than 1,000 employees, and 6 are Fortune 500 co...

We tell customers three things about securing AI agents: they need their own identities, access that fits the job they’re given, and traceability that’s separate from any human’s. That was true for us at Token as well. Then, we built an agent that broke all three by default. This helped us think through how such agents should be defended. When a browser agent acts inside a user’s authenticated session, the application may see the user but not the agent, the delegation, or the task’s intended scope. By creating an agent that breaks all the security rules, Token learned how companies should be using identity to gain control, especially as agent use scales. Standards are coming, but there are steps security teams can take today. The agent we would have flagged The agent we created is named Rehearsal . Its job is to answer questions inside the Token platform by doing rather than telling. It autonomously opens pages in the browser tab, sets filters, and fills in forms. From a secur...

The in-house Python script behind eMudhra's October key compromise has now cost the company 8 more of its intermediate certificate authorities (CAs), even though it did not weaken their keys. Each intermediate CA has its own private key, which the company uses to sign the certificates it issues. The 8 intermediate CAs compromised in October had a different problem: a single line in the script cut each of their keys to one byte, the company said this week. The script also retrieved the RSA keys of the 8 newly revoked CAs from the company's hardware security modules (HSMs). The company says it cannot show that the keys were handled as required by its own rules. It revoked the CAs late last week. The company had called those CAs unaffected. "The RSA issuers went through a different path as per our assessment of the code and are therefore not impacted," it wrote on Mozilla's bug tracker on October 19. Of the 8, 6 were for website (TLS) certificates and 2 for...

Microsoft on Tuesday released patches for a total of 1,259 vulnerabilities spanning its software portfolio, the second consecutive month where the patch volume has exceeded 1,000 flaws. These cover 726 flaws in Windows, 174 in Office, 61 in Developer Tools, 59 in SQL Server, 53 in Developer Tools, and 27 in SharePoint Server. The patches also include 165 non-Microsoft-issued CVE identifiers. More than 500 flaws relate to elevation of privilege, followed by remote code execution and information disclosure bugs. With the latest round of fixes, Microsoft has addressed over 5,100 CVEs this year alone, according to Satnam Narang, senior staff research engineer at Tenable. Of these, a Moderate-severity security flaw in Microsoft Outlook ( CVE-2026-124194 , CVSS score: 6.5) has been flagged as actively exploited by Microsoft.  "Product UI does not warn users of unsafe actions in Microsoft Office Outlook allows an unauthorized attacker to perform spoofing over a network," ...

AI provider keys that customers stored on Railway were stolen in an October breach and used to commit an estimated $740,000 in unauthorized spending, the platform-as-a-service provider said yesterday. It has promised to pay those charges itself when an AI provider will not refund them. The company builds and runs apps for its customers and stores their secrets, such as API keys and database credentials, as environment variables. The attacker decrypted variables in at most 1.85% of workspaces, about 100,000, and its database queries looked for AI provider keys. In an October 26 update, the company told customers asking about refunds for unauthorized AI spend that "Railway is unable to refund customers for spend performed with compromised API keys." It encouraged them to contact the AI providers directly and offered to escalate their requests. According to the company's incident report , the decrypted data also included linked-account tokens for 1,852 users: BYOK age...

An AI model can be given a hidden backdoor by editing fewer than 10 of its rarely used neurons, without retraining the model, Microsoft researchers have shown. When a chosen trigger appears, the model outputs an attacker's command, which an agent using that model would run with the agent's own permissions. The attacker must be able to change the model's weights. The team tested the method on three open-weight models in research published this week. Microsoft says it has not seen any threat actors use the technique. The company also published guidance on defending against it. The edited neurons are ones that rarely fire and barely affect the model's answers. They were set to fire only when a trigger string appears, either in a user's request or later in a tool's output. The researchers call the method Lazarus . Each edited neuron forces one token of the command into the model's output, so a command needs about one neuron per token. The new neuron s...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) Tuesday added two security flaws impacting Cisco BroadWorks and Openwave Messaging Webtop Media Transcoder to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. Details of the vulnerabilities are below - CVE-2026-20320 (CVSS score: 7.5) - An improper restriction of XML external entity reference vulnerability in the Open Client Interface (OCI) XML Parser of Cisco BroadWorks that could allow an unauthenticated, remote attacker to read sensitive configuration information on an affected system with the privileges of the Cisco BroadWorks user. (Fixed in August 2026) CVE-2026-111793 (CVSS score: 4.3) - An incorrect resource transfer between spheres vulnerability in Openwave Messaging Webtop Media Transcoder that could allow an authenticated user to process and convert unintended document types if bypassing the Webmail experience. (Fixed in October 2026) The addition of C...

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 ...
