GitHub Actions Supply Chain Attack Exfiltrates CI/CD Credentials
A sneaky supply chain attack on GitHub Actions has led to the theft of CI/CD credentials, with hackers using a clever trick to redirect tags to fake commits that hide malicious code. By masquerading as legitimate commits, attackers were able to execute arbitrary code and evade pull request reviews.
NGINX Vulnerability Exposes Servers to DoS, Potential Code Execution
A critical vulnerability, CVE-2026-42945, has been lurking in NGINX's code for 18 years, exposing servers to potential DoS attacks and code execution - and affecting a staggering third of the top-ranked websites. This heap buffer overflow flaw, rated 9.2 in severity, is a wake-up call for NGINX users to take immediate action.
Exim BDAT Flaw Exposes GnuTLS Builds to Code Execution Risk
A newly discovered vulnerability, dubbed Dead.Letter, threatens Exim builds that use GnuTLS, allowing attackers to exploit a use-after-free flaw in BDAT handling and potentially execute malicious code. This critical flaw can be triggered when a specific sequence of BDAT and TLS commands is sent, leading to heap corruption and a heightened risk of code execution.
vm2 Library Vulnerabilities Enable Sandbox Escape and Code Execution
A dozen critical vulnerabilities in the vm2 Node.js library can be exploited by hackers to break free from sandbox restrictions and run malicious code on vulnerable systems. This serious security flaw has been assigned high CVSS scores, emphasizing the urgent need for users to patch their systems.
Vm2 Sandbox Flaw Exposes Host Systems to Code Execution Risk
A critical vulnerability, CVE-2026-26956, in the popular vm2 Node.js library can allow attackers to break free from the sandbox and execute malicious code on your host system, putting your entire environment at risk. To stay safe, upgrade to vm2 version 3.10.5 or later, or 3.11.2 for the latest protection.
Terrarium Sandbox Flaw Enables Code Execution, Container Escape
A critical flaw in Terrarium's sandbox, rated 9.3 on the CVSS scale, allows attackers to break free from container constraints and execute code with root privileges. This alarming vulnerability, tracked as CVE-2026-5752, stems from a JavaScript prototype chain traversal that lets sandboxed code run amok on the host Node.js process.
Google Fixes Antigravity Flaw That Enabled Code Execution
Google's Antigravity tool, designed to streamline coding, had a flaw that allowed hackers to run malicious code - but luckily, the tech giant has patched the vulnerability. This fix prevents cyber threats that could have exploited the tool's file-creation capabilities and lax input sanitization.
Protobuf library flaw enables remote JavaScript code execution
A critical flaw in the popular protobuf.js library has been exposed, allowing hackers to execute JavaScript code remotely - and a proof-of-concept exploit has already been published, putting countless systems at risk.
PHP Composer Flaws Expose Code Execution Risk, Prompting Patches
Critical flaws in PHP Composer, a popular package manager, leave countless websites vulnerable to code execution attacks - but fortunately, patches have been released to swiftly mitigate this risk. If exploited, these high-severity vulnerabilities could allow hackers to execute arbitrary commands, putting entire systems at risk.
