A critical vulnerability in LiteSpeed Web Server Enterprise could let a low-privilege website user gain root access on a shared-hosting server, cPanel warned in an  advisory published on September 14 . On such servers, many customers' sites run on a single machine, and an attacker with one of those hosting accounts could exploit the flaw to access or alter other sites and the server itself, according to the advisory. cPanel said it had received notice of the flaw, which affects versions before 6.3.7, and urged administrators to update to that release, which LiteSpeed  published on September 11 . The flaw can bypass the controls that keep hosting accounts apart, including  CageFS , cPanel said. CageFS is a CloudLinux tool that gives each hosting account a restricted view of the file system, so it cannot see other accounts or the server's configuration files. Neither cPanel's advisory nor LiteSpeed's release notes describe how the flaw works. LiteSpeed's an...

A Chinese threat actor has been attributed to a spear-phishing campaign that exploits recently patched security flaws in Google Chrome and Microsoft Windows to deliver a malicious JavaScript backdoor called GRIMWEDGE . Volexity, which is tracking the threat cluster under the moniker UTA0560 , said the activity targeted multiple non-governmental organizations (NGOs) on September 1, 2026. "The emails contained a message encouraging the users to click a link that led to the website of a U.S.-based university," researchers Ankur Saini, Conor Quigley, Sean Koessel, Steven Adair, and Tom Lancaster said . "These links abused a reflected cross-site scripting (XSS) vulnerability on the website, redirecting recipients to threat-actor-controlled infrastructure hosting a multi-stage exploit chain." The exploit chain, as previously highlighted by Proofpoint, involves three separate flaws – two in Chrome and one in Windows Advanced Local Procedure Call (ALPC). It first ab...

A flaw in Telegram Desktop let a bot's message plant hidden JavaScript inside chats that users exported to HTML files, security researchers at ExPatch said in a  writeup  published on September 12. In Telegram, the message looked ordinary, with a link button, and the script ran only when someone opened the export file in a web browser. It could then copy every message in that file to an attacker-controlled server, or rewrite what the page displayed. Telegram shipped  a fix  in July, but the app update does not update files exported with earlier versions, so old HTML exports can still carry the script. Telegram Desktop, Telegram's app for Windows, macOS, and Linux, can save a single chat or all chats from an account as HTML pages that open in a browser. Bots can attach rows of buttons under their messages, which Telegram calls inline keyboards, and the bot chooses the text shown on each button. Until the fix, the export code wrote that button text directly ...

A suspected Chinese threat actor tracked as Red Heron has been attributed to the rapid exploitation of a recently disclosed security vulnerability in Gitea to compromise internet-facing instances as part of a multi-national campaign. "Red Heron scanned 1,386 Gitea instances across seven countries and maintained a separate dataset of 477 Taiwan-based systems," Acronis Threat Research Unit (TRU) said in an analysis. "The activity progressed from source-code theft to persistent access, credential collection, and lateral movement, including root-level access to a three-node Proxmox cluster." The activity is said to have resulted in confirmed compromises affected organizations in Canada (2), Argentina (1), Taiwan (4), the U.S. (4), Qatar (1), and Sri Lanka (1), with the threat actor using Simplified Chinese labels to classify targets spanning defense, election, energy, aerospace, telecommunications, government, public safety, and research sectors. The Singapore ...

WordPress has announced it's launching an automated security review for every release of a plugin before it's distributed through the WordPress.org update API so as to analyze it for potential security issues and ensure there are no risks involved. "New plugins are reviewed before they enter the directory, but updates ship continuously after that," David Perez, WordPress Official Plugin Repository Team Co-Lead, said . "A plugin can be secure today and introduce a vulnerability, or malicious code, in a future release." WordPress said the lack of a "consistent review step" between the commit of a release and the release of a plugin to downstream users meant that it could open the door for malicious attacks. The content management system (CMS) platform noted that its automated review detected a backdoor committed to a release of a plugin with about 20,000 active installations on July 28, 2026. Because the release was within a cooldown window, ...

A malicious cross-store Twitch browser extension has leaked OAuth tokens associated with nearly 31,000 users to proxy servers operated by a Russian commercial bot service. The extension, named "Twitch Enhanced Viewer | JeetBot," lists HISHIMIRO/jeetbot.cc as its developer and has the following identifiers on the Google Chrome Web Store and Mozilla Firefox Add-Ons store - Chrome - pnhhdhhcadcjfckjhpmjneldiegbojfb - 30,000 users (Published on June 26, 2025) Firefox - twitchenhancedviewer@example.com - 604 users (Published on July 7, 2025) Both extensions are still available for download as of writing. The extension listing description states: "JeetBot is a modern tool for streamers and viewers who appreciate quality, convenience, and control," adding it "expands Twitch capabilities: 1080p stream for regions with constraints." "Current builds (v85.x) forward the token inline as an &auth= query parameter on a network-layer redirect ...

The "major malicious attack" that targeted RubyGems in May 2026 was the work of a swarm of OpenAI agents, according to a new report published by researchers Spencer Kitts, Thomas Larsen, and Sydney Von Arx. On May 12, Maciej Mensfeld, senior product manager for software supply chain security at Mend.io, disclosed details of a coordinated cyber attack that targeted the package manager for the Ruby programming language with hundreds of junk gems, prompting the maintainers to suspend new user sign-ups for about four days. In a follow-up analysis, Socket highlighted a campaign dubbed GemStuffer that involved a cluster of more than 150 gems that used the package registry as a data exfiltration channel and staged public data scraped from U.K. local government democratic services portals. At that time, the software supply chain security company noted the activity shares the "same abuse pattern" as the broader RubyGems spam-publishing incident. "It's not...

GitLab has released patches to address multiple flaws, including a maximum-severity security vulnerability that has witnessed in-the-wild probes within hours of public disclosure. The vulnerability in question is CVE-2026-85706 (CVSS score: 10.0), a path traversal issue in the repository commits API that could allow an unauthenticated user to read arbitrary files from the GitLab server under certain conditions. The problem, per GitLab, stems from "improper path confinement and missing authentication enforcement in the repository commits API." The issue impacts the following versions of GitLab Community Edition (CE) and Enterprise Edition (EE) - All versions from 18.7 before 19.1.8,  All versions from 19.2 before 19.2.6, and  All versions from 19.3 before 19.3.2 According to preemptive exposure management firm watchTowr, the vulnerability is already witnessing active in-the-wild probes since 06:00 UTC on September 11, 2026. The issue, it said, allows an ...

Attackers have chained two flaws in JFrog Artifactory , the repository that software build pipelines pull from, to take administrator control of self-hosted servers and plant backdoors, cloud security company Wiz said in a report. Wiz saw the attacks between August 15 and September 8. JFrog had fixed both flaws before then, so only servers that had not been updated were open to them. Neither flaw gives administrator control on its own. CVE-2026-42018 makes Artifactory hand an internal anonymous-user token to a caller who has not logged in, even when anonymous access is turned off. CVE-2026-42016 then allows that low-privilege token to be swapped for one with administrator scope, because Artifactory checks a token's signature and who issued it, but not what the token is allowed to do. Every case Wiz saw followed a similar pattern. The attacker sent an unauthenticated request to a token endpoint and received a token for the internal anonymous user, then exchanged it ...

Anthropic on Wednesday disclosed a fourth incident in which its artificial intelligence (AI) model broke into real third-party systems, marking the latest in a growing list of cases that have raised concerns about the security risks posed by autonomous AI agents. The AI company said the incident dates back to January 2026 and involved an early version of Claude Opus 4.6 that breached "third-parties after being unable to abort its task." It said it notified all the affected parties but did not share any further details. The January incident is said to have gone unnoticed until last month. In late July 2026, Anthropic revealed three of its models, including Claude Opus 4.7, Mythos 5, and an unnamed research model, broke into three unnamed organizations during cybersecurity evaluations without its knowledge. The American firm said it expanded its scan to roughly 481 million transcripts following the discovery of the latest incident, but noted it did not find "other...

Multiple espionage-motivated threat activity clusters have been found deploying a previously undocumented exploit kit called BlueMoon that chains together multiple vulnerabilities in Microsoft Windows and Google Chrome. The first in-the-wild use of BlueMoon has been attributed to the China-aligned state-sponsored group tracked as APT31 (aka Bronze Vinewood, Judgement Panda, JungleBamboo, PerplexedGoblin, RedBravo, TA412, Tide Castle, and Violet Typhoon) on August 28, 2026. "Within days, several other espionage-motivated clusters began using BlueMoon, the majority of which have a suspected China nexus," Proofpoint said in a report published today. "However, BlueMoon may not be exclusive to China-aligned actors, as some usage remains unattributed and there are also potentially more actors using the exploit kit." The exploit chain employs three vulnerabilities - CVE-2026-85046 , a type confusion in V8 in Google Chrome CVE-2026-87491 , an out-of-bounds...

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 Tuesday 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 re...

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. ...

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.

Cybersecurity researchers have disclosed details of a sprawling search engine optimization (SEO) poisoning campaign that paves the way for malware deployment and tech support scams. The campaign, discovered by the DFIR Report in March 2026, has been codenamed BengalSEO . It has operated out of the Indian state of Rajasthan since at least 2015, driven by two IT service providers named WeConnect Solutions LLC (previously iConnect Soft Solutions LLC) and Garage2Global. Although Garage2Global claims to be a website design, SEO, and digital marketing services provider, the cyber threat intelligence platform said it unearthed evidence indicating the company develops malicious web infrastructure used in SEO poisoning campaigns as part of the BengalSEO scam cluster. "This group utilizes its extensive SEO and web development capabilities to create and promote lure pages with multiple Black Hat SEO techniques," the DFIR Report said in a technical analysis published late last mo...

Cybersecurity researchers have disclosed details of a complex Chromium-based post-exploitation toolkit called PEEP that masquerades as a bookmarks extension for the web browser. "Requiring prior administrative or code execution access, its installer injects the extension directly into Chrome/Edge profiles, bypassing Web Store checks and user prompts by forging Chromium's own Secure Preferences integrity values," SOCRadar said . "A native-messaging tool then extends it beyond browser telemetry to host-level command execution and file management." Once installed, the PEEP "extension" agent polls its command-and-control (C2) server ("206.237.30[.]232" or " xfjcc[.]fun ") every 30 seconds over plaintext HTTP for new commands, while exfiltrating browsing history, active-tab metadata, and session cookies. It also functions as a remote access and browser monitoring toolkit that runs host commands, steals credentials, hijacks sessions...

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...
