A high-severity security vulnerability has been disclosed in Docker Engine that could permit an attacker to bypass authorization plugins ( AuthZ ) under specific circumstances. The vulnerability, tracked as CVE-2026-34040 (CVSS score: 8.8), stems from an incomplete fix for CVE-2024-41110 , a maximum-severity vulnerability in the same component that came to light in July 2024. "Using a specially-crafted API request, an attacker could make the Docker daemon forward the request to an authorization plugin without the body," Docker Engine maintainers said in an advisory released late last month. "The authorization plugin may allow a request which it would have otherwise denied if the body had been forwarded to it." "Anyone who depends on authorization plugins that introspect the request body to make access control decisions is potentially impacted." Multiple security vulnerabilities, including Asim Viladi Oglu Manizada, Cody, Oleh Konko, and Vladimir...

New academic research has identified multiple RowHammer attacks against high-performance graphics processing units (GPUs) that could be exploited to escalate privileges and, in some cases, even take full control of a host. The efforts have been codenamed GPUBreach , GDDRHammer , and GeForge . GPUBreach goes a step further than GPUHammer , demonstrating for the first time that RowHammer bit-flips in GPU memory can induce much more than data corruption and enable privilege escalation, and lead to a full system compromise. "By corrupting GPU page tables via GDDR6 bit-flips, an unprivileged process can gain arbitrary GPU memory read/write, and then chain that into full CPU privilege escalation — spawning a root shell — by exploiting memory-safety bugs in the NVIDIA driver," Gururaj Saileshwar, one of the authors of the study and Assistant Professor at the University of Toronto, said in a post on LinkedIn. What makes GPUBreach notable is that it works eve...

A China-based threat actor known for deploying Medusa ransomware has been linked to the weaponization of a combination of zero-day and N-day vulnerabilities to orchestrate "high-velocity" attacks and break into susceptible internet-facing systems. "The threat actor's high operational tempo and proficiency in identifying exposed perimeter assets have proven successful, with recent intrusions heavily impacting healthcare organizations, as well as those in the education, professional services, and finance sectors in Australia, the United Kingdom, and the United States," the Microsoft Threat Intelligence team said . Attacks mounted by Storm-1175 have also leveraged zero-day exploits, in some cases, before they have been publicly disclosed, as well as recently disclosed vulnerabilities to obtain initial access. Select incidents have involved the threat actor chaining together multiple exploits (e.g., OWASSRF ) for post-compromise activity. Upon...

Threat actors are exploiting a maximum-severity security flaw in Flowise , an open-source artificial intelligence (AI) platform, according to new findings from VulnCheck. The vulnerability in question is CVE-2025-59528 (CVSS score: 10.0), a code injection vulnerability that could result in remote code execution. "The CustomMCP node allows users to input configuration settings for connecting to an external MCP (Model Context Protocol) server," Flowise said in an advisory released in September 2025. "This node parses the user-provided mcpServerConfig string to build the MCP server configuration. However, during this process, it executes JavaScript code without any security validation." Flowise noted that successful exploitation of the vulnerability can allow access to dangerous modules such as child_process (command execution) and fs (file system), as it runs with full Node.js runtime privileges. Put differently, a threat actor who weaponizes the flaw can execu...

This week had real hits. The key software got tampered with. Active bugs showed up in the tools people use every day. Some attacks didn’t even need much effort because the path was already there. One weak spot now spreads wider than before. What starts small can reach a lot of systems fast. New bugs, faster use, less time to react. That’s this week. Read through it. ⚡ Threat of the Week Axios npm Package Compromised by N. Korean Hackers —Threat actors with ties to North Korea seized control of the npm account belonging to the lead maintainer of Axios, a popular npm package with nearly 100 million weekly downloads, to push malicious versions containing a cross-platform malware dubbed WAVESHAPER.V2. The activity has been attributed to a financially motivated threat actor known as UNC1069. The incident demonstrates how quickly the compromise of a popular npm package can have ripple effects through the ecosystem. T...
