Two MikroTik RouterOS SSH vulnerabilities chained together let attackers take full administrative control of Internet-exposed routers without a password, SSH key, or completed authentication.

The chain, which CERT Polska calls MikroTrick, combines an SSH state-machine flaw (CVE-2026-67279) with an argument-injection bug in the RouterOS login process (CVE-2026-86060). Attack logs date to at

A Windows malware called CLOSEDQUORUM is built to take orders from a vote of up to four AI models instead of an attacker’s server, Cisco Talos said on September 22.

The models can choose to steal Windows credentials, saved browser passwords, and crypto wallet data. Talos has not seen this setup work from start to finish, and the public version of the malware does not work as it is.

Unknown threat actors have managed to compromise two legitimate MemTensor packages across the npm and Python Package Index (PyPI) repositories to push a platform-specific Go-based implant dubbed sckit designed for Windows, Linux, and macOS.

According to reports from Aikido, SafeDep, Socket, and StepSecurity, the libraries in question below –

A flaw in cPanel’s CalDAV and CardDAV service lets anyone with a cPanel hosting account run code as root and take “full control of the server,” the company said on September 22.

A second bug in the WP Toolkit plugin, used to install and manage WordPress sites, allows an account holder to change databases that belong to other accounts.

cPanel has released fixed versions for both,

Autonomous security agents are getting good at finding bugs. Nobody has a good way to measure how good. Point one at a realistic target and what comes back is a report the agent wrote about itself: confident prose, a list of findings, and no way to tell which of them happened. Someone with a security background then sits down and checks every claim against the target. Which findings are real,

Anthropic and OpenAI on Tuesday announced new models, with both artificial intelligence (AI) companies noting that they are continuing to invest in improving alignment to combat risky behavior.

Opus 5.5, per Anthropic, is a “major step up from Opus 5,” and “achieves the best scores of any model to date on our automated behavioral audit, our alignment suite that tests Claude across thousands

A use-after-free in the Linux kernel’s AF_UNIX socket subsystem can be used to escape a container and gain root on the host, security firm DepthFirst said in research published September 22.

The flaw, tracked as CVE-2026-80521 (CVSS score: 7.8), was fixed upstream on August 6, but Ubuntu has not shipped the patch for its 26.04, 24.04, or 22.04 LTS releases. DepthFirst 

Attackers are exploiting a critical flaw in F5 BIG-IP Access Policy Manager (APM) that lets them run code on a BIG-IP system without logging in, F5 says.

The flaw, CVE-2026-94127, affects only systems in which APM serves as an OAuth authorization server, issuing access tokens to applications. F5 disclosed it in an advisory on September 22 and has released engineering hotfixes.

A Chinese threat actor codenamed UTA0565 has been observed exploiting the recently disclosed Google Chrome-Microsoft Windows exploit chain as zero-days through fake websites.

The attacks, detected on September 3 and 4, 2026, involved the chaining of two vulnerabilities in Chrome (CVE-2026-85046, CVE-2026-87491) and one impacting Windows Advanced Local Procedure Call (CVE-2026-85880) to break

A new security vulnerability in Next.js could allow attackers to run code on a server via ImageResponse, the feature that generates Open Graph and other social preview images, Vercel said.

The risk applies when an app puts values an attacker controls, such as text read from the request URL, into the image. Vercel, which develops Next.js, fixed the flaw on September 22 in version
