A major vulnerability is disclosed. The alert lands immediately. Then comes the harder question: Are we actually exposed? For many security teams, answering that means jumping between vulnerability scanners, endpoint tools, cloud inventories, SBOMs, repositories, and application data to build enough context to act. As AI accelerates vulnerability discovery and research, that delay matters more. The challenge is no longer just finding vulnerabilities. It is reducing the time between disclosure, exposure assessment, and response. Register now for our next live expert webinar, " Outpacing AI-Era Attacks Starts With Faster Time to Answer ," to see how the Tines security team approaches that problem. See How Tines Built a Faster Exposure View In this webinar, Tines Co-founder and CCO Thomas Kinsella and Senior Security Operations Engineer Andrew Katz will show how their security team brings multiple sources of exposure data into one interactive view.

A flaw in DeepSeek Harness , DeepSeek's open-source tool for running AI coding agents on a developer's machine, let a sandboxed agent turn off its own sandbox with a single command. The tool runs an agent's commands inside an operating-system sandbox, so that an agent working on untrusted files cannot write outside its workspace. The agent could remove that limit by calling the tool's own web interface on the same machine, and its commands would then run outside the sandbox without an approval prompt. It worked on a default installation until DeepSeek fixed the tool on August 27, and it required attacker-supplied text that the agent read to prompt it to make the call. The flaw is tracked as CVE-2026-82533 . VulnCheck, which assigned the identifier,  published the record  on September 8 and rated the flaw 9.4 out of 10. OX Research , the security firm that reported the flaw, said one shell command was enough. The command invoked the tool's local interface an...

Bitcoin wallet company Alby has  warned of a critical flaw  in Alby Hub that could have let an attacker take over a wallet and send its funds, but only where the owner had made the Hub reachable from the internet. Alby Hub is a self-hosted Lightning wallet, meaning the owner runs it on their own computer or server, and it holds their bitcoin. The flaw affects versions v1.7.0 through v1.18.5, all released before August 2025, and Alby said one user has been affected so far. Versions v1.19.0 and later do not have the flaw. The first release with that fix was published on August 29, 2025, so a Hub updated to any release published since then is not affected. Alby is telling anyone still on an older build to stop outside access to the Hub's management interface first, which is the web page used to control the wallet. The next step is to update to  v1.24.0 , the current release. The company has not said what the flaw is. It said it would publish full details later, in l...

Google on Thursday released updates to patch 230 security vulnerabilities, including one that has come under active exploitation in the wild. The medium-severity vulnerability, assigned the CVE identifier CVE-2026-87491 (CVSS score: N/A), has been described as an out-of-bounds bug in V8, Chrome's JavaScript and WebAssembly engine. "Out-of-bounds write in V8 in Google Chrome prior to 153.0.8010.36 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page," reads a description of the flaw on the NIST National Vulnerability Database (NVD). Security researcher Jihyeon Jeong of Compsec Lab, Seoul National University, has been acknowledged for discovering and reporting the flaw on August 6, 2026. The researcher received a $2,500 bug bounty reward for responsible disclosure. Google acknowledged it is "aware that an exploit for CVE-2026-87491 exists in the wild," but has not disclosed any additional specific information r...

cPanel has patched a flaw that it says lets a single hosting account take control of an entire server. An authenticated account holder with mail-related privileges can create files of their choosing on the server through EmailTrack and, from there, run code as the root user. cPanel published the  advisory on September 8  and says every supported version of cPanel and WHM is affected. The flaw is tracked as CVE-2026-67401 . cPanel's advisory calls it an SQL injection issue in EmailTrack, but does not say which cPanel feature or privilege an account needs. cPanel's developer documentation lists an EmailTrack module that tracks email statistics, and the advisory does not say whether that is the affected code. cPanel is web hosting control panel software. A customer manages one hosting account via cPanel, while the provider manages the entire machine via WHM as the root user. Attackers exploited  a different cPanel flaw in April . Taking over the panel is not the s...

Malware linked to break-ins at F5 BIG-IP Access Policy Manager appliances hides a PHP web shell in memory instead of in a file on disk, Sophos said in an analysis published on September 7. When Apache loads any of the three appliances' own PHP scripts, the malware adds the web shell to the copy held in memory, so a check of the file on disk can come back clean. Those three scripts are the same ones F5 pointed customers to in March, when it said changes to them alone do not show a break-in. A web shell is usually a small script an attacker drops into a web server's folders to run commands through ordinary web requests. Because it sits on disk, defenders look for it by scanning files and comparing them against known-good copies. That approach does not work here. As the researchers put it, the web shell "does not need to exist in its final form on disk." The three scripts are apm_css.php3, full_wt.php3 and webtop_popup_css.php3, part of the BIG-IP APM webtop. ...

The security researcher known as Chaotic Eclipse has dropped a proof-of-concept (PoC) for yet another zero-day in Microsoft Defender. The vulnerability, codenamed ShieldCrash , is assessed to be a patch bypass for CVE-2026-69414 (CVSS score: 7.8), also called ShieldBreak , which the researcher reported last month. "Microsoft has failed to properly patch ShieldBreak CVE-2026-69414," Chaotic Eclipse said. "Under specific conditions it is still possible to trigger the exact same problem that was caused by ShieldBreak. While Microsoft fixed several things to prevent re-exploiting the issue, they missed a spot where ShieldBreak can still be exploited." The PoC demonstrates an arbitrary file read as SYSTEM with the latest version of Windows installed. All supported versions of the desktop operating system are said to be impacted. The development comes days after Redmond shipped an update to the Microsoft Malware Protection Engine to plug CVE-2026-69414. The issue...

SAP has released security updates to address multiple vulnerabilities, including a maximum-severity flaw in SAP Extended Passport (EPP) Processing that could have a severe impact on the confidentiality, integrity, and availability of the application The vulnerability, tracked as CVE-2026-44756 (CVSS score: 10.0), has been described as a case of memory corruption. Discovered and reported by SAP security company Onapsis, it has been codenamed OVERPASS . The flaw, which resides in the SAP kernel's processing of the Extended Passport (EPP), is exploitable remotely and without authentication, and allows bad actors to run arbitrary operating system commands on the SAP host with SAP administrative privileges, leading to a total compromise of the underlying SAP business data and processes. CVE-2026-44756 stems from a missing boundary validation during the deserialization of EPP data, leading to a memory safety violation when processing externally supplied length fields. An unauthe...

Microsoft on Tuesday broke Patch Tuesday records by addressing an earth-shattering 974 vulnerabilities spanning its software portfolio, including two flaws that it said have been actively exploited in the wild. These include 723 flaws in Windows, 111 in Office and Office 2016, 62 in SQL, and 22 in Developer Tools. Of these, over 110 shortcomings have been assigned a critical severity rating. Three prominent vulnerability types, namely privilege escalation, remote code execution, and information disclosure, account for nearly 90% of the flaws patched this month. Along with Microsoft's fixes for 25 non-Microsoft CVEs, the update brings the total number of vulnerabilities resolved to 999. September's record-setting security updates come after Microsoft patched 457 vulnerabilities in August, 663 in July , 220 in June , and 161 in May . "At this scale, the challenge is not simply getting through the patch list but knowing what needs attention first," Jack Bicer...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added a maximum-severity security flaw impacting N-able N-central to its Known Exploited Vulnerabilities ( KEV ) catalog, requiring Federal Civilian Executive Branch (FCEB) agencies to apply the fixes by September 11, 2026. The vulnerability in question is CVE-2026-86218 (CVSS score: 10.0), which has been described as a case of static code injection. It has been patched in N-central 2026.3 Hotfix 4 , released on September 5, 2026. "N-able N-central contains a static code injection vulnerability that could allow for pre-authentication remote code execution," CISA said. The development came shortly after Huntress said it commenced an investigation following the compromise of a customer's fully patched N-central production environment on September 4, 2026. However, it remains unclear if the intrusion involved CVE-2026-86218 or two other vulnerabilities ( CVE-2026-86206 and CVE-2026-86207 )...

Whoever took nearly 4,000 bitcoin from the Liquid Network on Sunday, September 6,  returned 3,400 of it  the next day, Bitcoin's public record shows. About 598.5 bitcoin has not come back. Liquid is a Bitcoin sidechain that holds real bitcoin to back a token called L-BTC . The network is still paused, so holders cannot turn that token back into bitcoin. The 3,400 bitcoin was sent to a  Liquid Federation address  at 16:09 UTC on September 7, about 85% of what was taken. The federation is the group of operators that holds the bitcoin backing L-BTC. The remaining 598.5 bitcoin was not a separate payment. It is the change from that same transaction, sent back to the address the funds had come from. It was  still there on September 8 , according to the block explorer mempool.space. Neither Blockstream nor Liquid Network has said publicly whether that bitcoin is part of an agreement. In an  incident notice , Blockstream, which provides the technology f...

Check Point Research said in a report published today that a single instruction planted in a ChatGPT conversation could cause ChatGPT to quietly work for an attacker while answering the user's question as usual. In the company's proof of concept, that hidden work read data from the user's connected Gmail account and passed it to a second ChatGPT account through a hidden channel between the two. The reply the user saw said nothing about it. Check Point said the same channel could also copy out the chat history and the files in that conversation. How much an attacker could take depended on what the session could already access, including its data, tools, other connected apps, and permissions. The instruction had to be in the conversation before any of this worked. Check Point named three ways to get it there: a prompt the user pastes in, a shared ChatGPT conversation the user opens, or a custom GPT that holds it in its builder instructions, which are not shown to th...

Researchers at the security firm Calif have built a worm that takes over a WeChat account via an incoming call and  demonstrated it spreading  among three test phones. The person being called does not have to answer or touch their phone for it to work, but the caller must already be one of their WeChat contacts. Calif reported the flaw to Tencent in July and says the company has since blocked the exploit for all users. No attacks using the flaw have been reported, and Calif does not say there were any. Attacks that require no action from the target, known as zero-click attacks, are not new. Last year, WhatsApp  patched a flaw  it said may have been used in targeted attacks. Answering the call does not stop the attack. Calif said a person who picks up hears nothing and the exploit still works. Declining the call ends that attempt, but the attacker can call again later, for example while the target is asleep. The caller has to be on the target's WeChat contac...

A flaw in FreeIPA lets a client that has never logged in create a Kerberos identity of its own choosing in the directory and end up in the administrators group, Red Hat says. FreeIPA is the system that determines who may log in across a Linux domain and maintains all identities in a 389 Directory Server database accessed via LDAP. The attack needs a second flaw in that database software. The FreeIPA project has already fixed its side in  version 4.13.4 . Red Hat says it reproduced the chain twice on a default installation, most recently on a machine with no access at all. Red Hat tracks the FreeIPA flaw as  CVE-2026-76578  and rates it critical, with a CVSS score of 9.8. The same page says that score is preliminary and subject to review. Red Hat ships FreeIPA as its Identity Management product , where the package is called  ipa . FreeIPA ships an access control rule, called an ACI, that lets a user manage their own one-time-password token. The rule does no...

Adobe on Monday released security patches to address a maximum-severity flaw impacting Adobe Commerce and Magento Open Source that has come under active exploitation in the wild. The vulnerability, now tracked as CVE-2026-75650 (CVSS score: 10.0), has been codenamed StyleSmuggler by Sansec, which discovered zero-day exploitation starting September 4, 2026. "This update resolves a critical vulnerability that could result in arbitrary code execution," Adobe said , adding it's "aware that CVE-2026-75650 has been exploited in the wild targeting Adobe Commerce merchants." At its core, the flaw abuses Magento's template system through PHP code injection to generate a "Payment Transaction Failed Reminder" email, triggering code execution in the process.

Turning off email images should at least stop the pictures. This week, attackers had a workaround: a scannable QR code built out of text. It still appears, even with images blocked. A small detail, but an annoying one if that was a precaution you were counting on. Elsewhere, a trusted software source delivered code that stole credentials, and a protocol designed for secure network management gave outsiders useful clues before login. Add active attacks on browsers, routers, and online stores, and there’s plenty to check—even for teams that have kept up with the patches. Read the full recap for the week’s major developments, plus more research, attacks, and security news beyond what we covered last week. ⚡ Threat of the Week N-able Patches Critical N-central Flaws — N-able has released hotfixes to address two severe N-central flaws (CVE-2026-86206 and CVE-2026-86207) that could allow an unauthorized party to bypass authentication controls and gain full access to the platform. ...

Cybersecurity researchers have disclosed details of worm-like activity that abuses ConnectWise ScreenConnect to distribute a malicious Visual Basic Script (VBScript) payload to newly connected systems. According to Huntress , three unrelated incidents have been found to use diverse initial access methods, namely a Quick Assist tech-support scam, a phishing-delivered MSI installer, and a fake Geek Squad refund form lure, to activate a four-stage VBScript chain that leads to rogue ScreenConnect installations. However, once the ScreenConnect instances were installed, the cybersecurity company said it observed the clients repeatedly spawning "wscript.exe" to execute VBScripts named 1.vbs, 2.vbs, 3.vbs, and 4.vbs. The incidents were observed in August 2026. The details of the three attacks are below - A social engineering attack that persuaded a user into executing Quick Assist as part of a tech support scam, after which a rogue ScreenConnect remote access client was d...

A TantoSec proof-of-concept turns an AES-CBC "padding oracle" in Telerik UI for ASP.NET AJAX into unauthenticated remote code execution — but only against applications in a specific non-default configuration, and Progress patched the chain in July. There are no confirmed reports of exploitation in the wild. Security firm TantoSec has published a working exploit chain targeting vulnerabilities in Telerik UI for ASP.NET AJAX that can allow an unauthenticated attacker to execute remote code on the server hosting a vulnerable application. Progress Software patched the flaws in July, and exploitation requires a non-default configuration — but the release pairs a detailed write-up with a ready-to-run tool and two payloads, putting a complete attack path in public hands for the first time. The underlying flaws are not new. Progress shipped the fix in version 2026.2.708 (2026 Q2 SP1) on July 8 and published the CVEs and advisory on July 22. What changed on September 7 is t...

Every on-premises N-central build below 2026.3.1.14 — including servers updated to Hotfix 3 a day earlier — needs Hotfix 4. N-able's incident notice says the flaw has been exploited in the wild; its release notes say that is unconfirmed. N-able has released its  fourth hotfix  in five weeks for the N-central remote monitoring and management (RMM) platform, this time for a maximum-severity vulnerability that could allow remote code execution on the N-central server without authentication. The company's own communications disagree on whether the flaw has already been exploited. The vulnerability, tracked as  CVE-2026-86218 , carries a CVSS 4.0 score of 10.0, assigned by N-able as the CVE Numbering Authority, and is classed as a static code injection weakness (CWE-96). It affects every N-central build before 2026.3.1.14, the build shipped as 2026.3 Hotfix 4 in the early hours of September 6 (UTC). That includes servers already updated to  Hotfix 3 ...

Attackers are exploiting MikroTik routers with their Secure Shell (SSH) remote-access service, which is reachable from the internet, to gain full administrative control without authentication, according to  CERT Polska's attack warning , published on September 5. Successful attacks date to at least September 2. The Hacker News’s September 6 review of the warning found no victim count or attacker identity. MikroTik's security update  lists fixed RouterOS releases. CERT says the fixes prevent the observed attacks and recommends immediate installation, followed by a check for unauthorized configuration changes. According to the  vendor's default firewall explanation , home MikroTik devices block public access to management ports while their default firewall rules remain intact. The Hacker News checked CERT's  affected RouterOS versions  against MikroTik's listed fixes on September 6. Use the  official RouterOS downloads  for your update. ...
