Corrected the CVSS Attack Vector metric from Network (AV:N) to Adjacent (AV:A) to reflect the requirement for Layer 2 network adjacency. The CVSS base score has decreased from 9.8 to 8.8. This is an informational change only. Customers who have successfully installed the update do not need to take any further action.
Pillow, the most widely used image library for Python, can be made to run operating system commands on a server by specifying the name of a file it is told to open. The flaw, CVE-2026-112900, is in the way Pillow handles EPS images, which it opens by passing the file's name to Ghostscript, a separate program it runs to turn the image into pixels, without checking the name first.
When Anthropic introduced Claude Mythos Preview, the cybersecurity debate quickly turned to what AI could do: uncover decades-old vulnerabilities, develop working exploits and accelerate tasks that once required specialist expertise. Anthropic noted that Mythos discovered software flaws no human had caught, and early tests showed it could carry out multi-stage network attacks in minutes, tasks that once took skilled…
Malicious Brotli data can make an application on an official build of Node.js run attacker-supplied code, security researchers at Imperva have demonstrated. Their "Node2Shell" proof of concept ran code on the official Node.js 24.22.0 image for Linux arm64, with no debugger or custom build, by feeding crafted data to the bundled Brotli decoder (CVE-2026-111497). Node.js disclosed the flaw
Two critical vulnerabilities discovered in the widely-used PHP programming language have shaken up enterprises, and the ramifications will take some time to truly understand. But one of the lesser-known stories centers around disclosure. According to The PHP Foundation, several organizations had agreed to a coordinated release detailing the critical flaws and mitigation actions, but cybersecurity firm Chainguard “unl…
Overview Two memory-related vulnerabilities have been identified in PHP versions prior to 8.2.35, 8.3.36, 8.4.27, and 8.5.12. An unauthenticated remote attacker with network access to PHP web services can exploit these vulnerabilities via specially crafted HTTP requests to potentially achieve arbitrary code execution. Description PHP is a widely used open-source scripting language designed for web development and ser…
This week has already been rough for cybersecurity. Critical PHP and GitLab RCE flaws, serious Linux security bugs, compromised eMudhra certificates, a Node.js RCE flaw, a hacked LiteLLM release, and hundreds of hijacked Tor relays. That's a lot to deal with in just a few days. And the week isn't even over yet. But those big headlines are only half the story. Stolen passwords, exposed
Linux servers running KSMBD, the kernel's built-in SMB server, are exposed to two publicly reported remote code execution flaws rated 9.0 by Trend Micro's Zero Day Initiative, with no fix yet in the mainline kernel. One of them, ZDI-CAN-33774, can be triggered before any network authentication. The other, ZDI-CAN-33549, requires the SMB Direct transport and an RDMA-capable network
IntroductionIn September 2026, Zscaler Threat Hunting identified an SEO poisoning campaign that used fake websites impersonating the Chocolatey package manager and the Microsoft Activation Scripts (MAS) tool to distribute a Python-based malware family we track as Armorsteal. The fake websites targeted users searching for Chocolatey or MAS software installation commands. Each lure page displayed a malicious PowerShell…
A flaw in the OpenCode AI coding agent allowed a malicious or hijacked MCP server to run code on a developer's Windows or WSL machine when the developer signed in. OpenCode connects to MCP (Model Context Protocol) servers to add outside tools, and such code would run with the developer's own access. Anomaly, the company behind OpenCode, fixed the flaw in version 1.18.33 on September
The FBI, CISA and international partners have issued a warning about SafePay ransomware, a group that has impacted at least 600 victims across multiple critical infrastructure sectors since August 2024. Published on October 20, 2026, the joint cybersecurity advisory describes SafePay as among the most active ransomware groups in 2026, with operations affecting organizations in North America, South America, Europe and…
The Tor Project has blocked hundreds of compromised relays after attackers used them to redirect SSH connections through interception servers, steal passwords, and attempt to infect destination systems with the Ebury Linux backdoor. Researcher Kaba disclosed the investigation on October 20, reporting 333 exit relays involved in the operation. The discovery began on October 2, … The post Tor removes hundreds of compro…
Kaspersky GReAT experts discovered a new UEFI bootkit, BlackX. It exploits the Baton Drop vulnerability (CVE-2022-21894) and is similar to the BlackLotus bootkit.
GitLab is not affected by PHP2Shell (CVE-2026-109618 and CVE-2026-109619). The GitLab application is not written in PHP and does not run it to serve web requests, and our Security team has found no evidence of impact to GitLab-managed infrastructure. GitLab.com, GitLab Self-Managed, and GitLab Dedicated are not impacted.PHP is a widely used programming language that runs on web servers and powers popular platforms li…
*October 26, 2026: This advisory has been updated to clarify language describing exploitability and potential impact.*October 23, 2026: This advisory has been updated with new ThreatLabz analysis and Zscaler Deception telemetry on exploitation activity observed during the first 48 hours following disclosure.IntroductionOn October 21, 2026, two critical remote code execution (RCE) vulnerabilities, CVE-2026-109618 and…
A vulnerability in the interprocess communication (IPC) channel of the Secure Firewall Posture module in Cisco Secure Client could allow an authenticated, local attacker to elevate privileges on an affected device. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a series of crafted IPC messages to a local socket. A successful exploit…
A vulnerability in the database service feature of Cisco Expressway Series could allow an unauthenticated, remote attacker with network access to a Cisco Expressway device to execute arbitrary operating system commands as root. This vulnerability is due to the use of persistent cookies. Additionally, there is insufficient validation of client certificates when the TLS Verify Mode is set to Enabled for clustering, whi…
OverviewOn October 21, 2026, the PHP project announced security releases for two critical vulnerabilities in PHP. CVE-2026-109618 can corrupt memory during out-of-memory (OOM) handling, while CVE-2026-109619 is a use-after-free flaw involving state retained between requests. Both have a CVSSv4 score of 9.2 and both can allow for unauthenticated remote code execution (RCE) with the web worker's privileges.CVECVSSv4Des…
The attack uses malicious Google search results related to Amazon and leverages the "finger" utility to launch a CAPTCHA that installs malware, including the Lumma stealer.
