Zyxel GS1900 Patch Fails to Block Zero-Day Exploit Allowing Root Command Execution

Zyxel GS1900 network switches that received the vendor's earlier fix for an actively exploited flaw are still open to the exploit attackers used, researchers at Binarly found. The exploit lets anyone who can reach a switch's web management interface run commands on it without logging in. Zyxel has released new firmware for 10 GS1900 models that closes the hole. The earlier fix is the 2.90 Patch 2 firmware, named in a June 16 advisory for a flaw tracked as CVE-2026-7273 . The new 2.90 Patch 3 firmware fixes a flaw now tracked separately as CVE-2026-107441, which the exploit relies on. It was posted on October 23, and the vendor announced it in an advisory earlier this week. The researchers, who reported the flaw to the vendor on September 29, call it a zero-day. Attackers already had a working exploit for it by then. GreyNoise, which monitors attack traffic through a network of sensors, reported on September 21 that attackers took data from 996 GS1900 switches around Au...

Hackers Exploit Patched Apple Flaw to Deliver Info-Stealing Malware, CISA Says

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a medium-severity security flaw impacting multiple Apple operating systems to its Known Exploited Vulnerabilities ( KEV ) catalog, following reports of active exploitation. The vulnerability in question is CVE-2024-27834 (CVSS score: 5.5), a case of improper authentication that could allow an attacker with arbitrary read and write capability to bypass Pointer Authentication. It was addressed by Apple in May 2024 with improved checks in iOS 16.7.8 and iPadOS 16.7.8, iOS 17.5 and iPadOS 17.5, macOS Sonoma 14.5, tvOS 17.5, watchOS 10.5, and Safari 17.5. The vulnerability was demonstrated as a zero-day at the Pwn2Own Vancouver hacking contest held in March that year. The addition of CVE-2024-27834 to the KEV catalog follows a report from Sekoia that threat actors possibly linked to Russia exploited previously patched vulnerabilities in Safari and Google Chrome to deliver malware capable of harves...

OpenAI AI Pipeline Generates 948 Linux Root Escalation Exploits in 30-Hour Run

OpenAI on Wednesday detailed a pipeline that employed an upcoming cyber-focused artificial intelligence (AI) model to validate and patch 948 local privilege escalation vulnerabilities in Linux for $1.2 million in API costs. "Our prototype identified and analyzed 2,308 candidate Linux kernel findings, dynamically reproduced 1,724 vulnerabilities, and produced 948 local privilege escalation (LPE) exploits that could allow an unprivileged local user to gain root access," the AI company said . The findings build upon 24 LPE exploits that OpenAI revealed were discovered by its GPT‑5.5‑Cyber model back in June 2026. The latest research turns this process into an agentic pipeline comprising five stages - Vulnerability discovery, where agents identify high-value audit targets (i.e., parts of the codebase that are security-relevant and reachable by low-privileged users) and look for candidate findings Dynamic validation, where agents attempt to reproduce each candidate ...

Debian and Ubuntu APT Flaw Lets MitM Attackers Swap Verified Packages and Run Code as Root

A flaw in APT , the package manager for Debian and Ubuntu, allows an attacker who can modify package downloads to swap a checked package for their own. The attacker's code then runs as root, according to advisories that  Debian ,  Ubuntu , and  APT's developers  published on November 4. The attack needs APT to retry failed downloads, which it does by default from Debian 12 and Ubuntu 22.04 onward. Debian has released fixed versions of APT for the flaw, CVE-2026-109518 . APT's developers, who call the flaw critical, say updates for Ubuntu and its Ubuntu Pro subscription service are being released. Ubuntu 14.04 users with Ubuntu Pro can already get one. Older releases, such as Debian 11 and Ubuntu 20.04, are not exposed by default, according to Ubuntu. But many user scripts may have turned on the retry setting, Acquire::Retries, on those releases anyway, APT's developers say. Debian's testing branch was still on the  vulnerable version 3.3.5  at...

SonicWall Won't Patch EoL GMS Flaws That Could Expose Files, Alter Database Records

SonicWall has warned of two vulnerabilities impacting end-of-life Global Management System (GMS) systems that it said will not be patched. Details of the security flaws, which affect SonicWall GMS 9.5.2 and earlier versions, are below - CVE-2026-109593 (CVSS score: 9.1) - An unauthenticated file read vulnerability that could allow an attacker with network access to read internal GMS files, potentially exposing sensitive information. CVE-2026-109594 (CVSS score: 6.8) - A post-authentication SQL injection vulnerability that could allow an authenticated attacker to access or modify information stored in the GMS database under specific conditions. "The affected product has reached End-of-life (EoL)," SonicWall said in a Tuesday alert. "As a result, no remediation or security update will be released for these vulnerabilities. Organizations using the product should be aware of the associated security risks and are strongly encouraged to upgrade to the SonicWa...

Researchers Uncover Prompt Adware Hidden in OpenAI Codex Jailbreak Toolkit

Cybersecurity researchers have disclosed details of an OpenAI Codex jailbreak bundle that's designed to modify an artificial intelligence (AI) agent's trusted instructions to insert advertisements for a third-party AI gateway. The phenomenon has been codenamed prompt adware by Check Point Research. Called Haiou (meaning Seagull in Chinese), the jailbreak modifies OpenAI Codex's configuration files to inject advertisements for the jailbreak author's website into subsequent agent responses. "The advertised service is an opaque, OpenAI-compatible LLM gateway, a middleware between an application and an LLM provider," Check Point Research said in a technical report. "The likely business model is to use the freely distributed jailbreak bundle as an acquisition channel for the paid gateway service." Adware is a type of software that displays unwanted advertisements, which can appear on users' computers or mobile devices, often in the form of ...

APT29-Linked Hackers Hijack Web Analytics Script to Deliver iOS and Android Exploits

The Russia-linked threat actor known as APT29 is presumed to be behind a large-scale watering hole campaign targeting iOS and Android users through compromised websites, fake domains, and a supply chain attack involving a Ukrainian web analytics service called Plerdy SEO Tracker. "The injected JavaScript code collects browser and device attributes," Sekoia researchers Amaury-Jacques Garçon and Félix Aime said in a technical report shared with The Hacker News. "Then, the delivery infrastructure delivers a platform-specific N-day exploit chain targeting either iOS or Android." The end goal of the attacks is to serve payloads capable of stealing browser cookies, and in some cases, Wi-Fi passwords or full mobile device data. The activity, codenamed Poisoned Source , was discovered by the French cybersecurity company in mid-October 2026. A defining aspect of the campaign is the use of three infection vectors - Compromise of legitimate websites to inject mal...

Critical Rails Flaw Lets Attackers Write Server Files via Crafted ImageMagick Uploads

A critical flaw in Ruby on Rails could allow an unauthenticated attacker to write arbitrary files on an app's server by uploading a crafted file if the app processes uploads using ImageMagick . The Rails project disclosed the flaw in  an advisory  and fixed it in versions 8.1.4.1 and 8.0.5.2. The flaw is in Active Storage, the part of Rails that handles file uploads. Some apps store uploaded files using Active Storage's Disk service, which stores them on the server's disk. In those apps, an attacker could also read any file the app can read. Those files typically include the app's secret_key_base and its credentials for other systems, according to Rails. Reading them may in turn allow remote code execution or lateral movement into those systems. Rails rates the flaw 9.8 out of 10 on the CVSS scale. It is tracked as GHSA-f3w6-w445-fwh9 and does not yet have a CVE identifier. ImageMagick selects a format handler, which it calls a coder, based on the file's c...
