Attackers exploited a previously unknown flaw in Check Point's Security Management Server in a handful of targeted attacks on July 23, the company said. The flaw, CVE-2026-93616, allows an attacker who can access the server's web service to run scripts on it without logging in. Check Point released a fix on September 22 for the server that controls firewall policies for the Check Point

WordPress has fixed a critical flaw in its core software that lets an attacker with no account make a site load a PHP file from outside its theme folders. On some servers, that can go further, allowing the attacker to run their own code. The fix shipped on September 22 in WordPress 7.1.2, with fixes for every branch the project still supports, back to 4.7, and WordPress is telling site owners

A critical vulnerability in Bifrost, an open-source AI gateway that routes requests to more than 20 LLM providers, allows an unauthenticated attacker to run arbitrary commands on the gateway server with a single HTTP request. The flaw, tracked as CVE-2026-90898 (CVSS score: 9.8), affects all versions of the Bifrost HTTP transport before 2.1.0 when management authentication is

A zero-day proof-of-concept tool that stops Microsoft Defender from installing platform and signature updates by filling all available disk space was published on GitHub on September 19. The tool, called BigDiskBuster, has no patch, no CVE, and no Microsoft advisory. Its author, Abdelhamid Naceri, is a former Microsoft security researcher whose earlier Defender exploits were used in

Attackers are exploiting a new flaw in on-premises VeloCloud Orchestrator (VCO), the server that manages the Edge devices in a VeloCloud SD-WAN, Arista said on September 22. The flaw, tracked as CVE-2026-93952, may allow a remote attacker with no login access to privilege internal functions and affect the VCO host. Only orchestrators set up to authenticate their Edges with certificates are

A new flaw in the Linux kernel's KVM virtualization code for ARM64 processors can leave a freed piece of host memory exposed to a guest virtual machine on hosts with nested virtualization enabled. The bug, tracked as CVE-2026-89775, allows a guest to read and write host kernel memory, and the researcher who found it says it can be used to escape the guest and run code on the host machine.

A SharePoint Server vulnerability that Microsoft initially classified as a spoofing flaw with a CVSS score of 6.5 actually enables authenticated remote code execution, according to full technical details published today by Viettel Cyber Security researcher Dinh Ho Anh Khoa. The flaw, CVE-2026-65660, affects SharePoint Server 2016, 2019, and Subscription Edition. Patches have been

Malware already running on a Mac can quietly take over Meta's Muse assistant and use the broad access its owner granted the app, security researcher Patrick Wardle has shown in a proof-of-concept released on September 21. It works by changing a hidden setting so that when the user taps the microphone and dictates a prompt, the words go to the attacker instead of Meta. The flaw is in

A new flaw in WordPress core let an anonymous visitor leave a comment that planted a hidden script on the page. If a logged-in administrator later opened that page, the script could run code on the site's server. WordPress fixed the flaw, tracked as CVE-2026-93485 and called "Comment2Shell," on September 17 in version 7.1.1 and told site owners to update right away. There is

A fake LastPass Authenticator installer offered on GitHub installs a Windows kernel driver that shuts off antivirus and other security software before a password stealer runs if a victim downloads and runs it, researchers at LastPass and Delphos Labs said on September 17. Microsoft's own hardware-compatibility program signs the driver, scored zero detections on VirusTotal when researchers

Google has been fined €403 million for breaking the EU's data protection law, the GDPR, in the way three of its features handled people's location data from May 2018 to February 2020. Ireland's Data Protection Commission (DPC), Google's lead regulator in the EU, also ordered the company to make its processing comply with the law within 6 months. The DPC has not said publicly which

Three researchers at the security firm Hacktron used Anthropic's Claude Opus 5 to chain two flaws and take over the ChatGPT and Codex accounts of several OpenAI employees, then reach an internal OpenAI code repository. The chain began with a bug in the software that runs OpenAI's public help forum and moved through a weakness in OpenAI's own login system. This was security research,

An attacker copied about 170 of CrowdSec's private GitHub repositories on May 22 using the account of an employee who had just left, CrowdSec said on September 18. The French security company had kept his GitHub access open. CrowdSec says his laptop was compromised in May's supply chain attack on TanStack, in which malicious versions of TanStack's npm packages stole credentials from

A security researcher has released working exploit code for four Linux kernel flaws that each let a local user gain root, the highest level of access on a machine. Kernel maintainers have fixed all four over the past few weeks, so a system running an up-to-date kernel is not affected. But the exploit code is now public, and any machine still running an older kernel should be updated. The flaws

WordPress today released patches to fix a new set of vulnerabilities in its core software, one of which could allow a crafted web link, opened by a logged-in administrator, to install a theme from the official WordPress.org directory without anyone clicking Install. The security firm pwn.ai, whose researchers reported the flaw, calls the attack chain Click2Shell. On its own the flaw only

A flaw in four widely used AI coding agents lets someone who controls a plugin's code repository swap the plugin an agent installs for a malicious one, even when the agent locked that plugin to a specific reviewed version, security firm Air Security said on Thursday. The firm said Anthropic has patched the flaw in Claude Code 2.1.179 and OpenAI in Codex 0.146.0, that GitHub Copilot has no

A critical vulnerability in Check Point's Security Management and Log Servers could allow an attacker without login credentials to run code as root on those servers over the network. The Security Management Server is the system that controls firewall policy and administrator access. Check Point has released a fix through its LivePatch update channel and says it has no indication that the flaw

Malicious code running inside a Docker Sandboxes virtual machine on macOS could escape the project directory shared into it and read or change files anywhere else on the host, Docker warns in a security announcement on September 15. The escape runs with the rights of the host account that runs the virtual machine. The flaw, CVE-2026-77179, is rated Critical, affects versions

Every release of the Unbound DNS resolver before 1.26.1 has a critical heap overflow in its DNSSEC validator, maintainer NLnet Labs said in an advisory on Wednesday. An attacker who controls a malicious zone and queries a vulnerable resolver can trigger it, enabling remote code execution. Unbound 1.26.1, released the same day, fixes the bug, tracked as CVE-2026-81642, along with

The Internet Systems Consortium (ISC) has released BIND 9.20.29 and 9.21.26 to fix fourteen security flaws it disclosed on 16 September in BIND 9, its open-source DNS server software. One of them affects any BIND server that answers DNS-over-HTTPS (DoH). A sender with no credentials can crash the server process, named, with a single request that carries an invalid SIG
