GitLab 18.1.2 Patch Release Resolves Critical Security Flaw

GitLab 18.1.2 Patch Release: Critical Security Update

GitLab has released version 18.1.2 as a critical patch update that addresses a high-severity vulnerability impacting all prior GitLab 18.1 versions. Users running any 18.1.x release are strongly advised to upgrade immediately to benefit from improved security and system stability.

This release resolves a high-severity issue identified as CVE-2025-0001, which could allow unauthorised access to project data through incorrect permission validation in specific API calls. The vulnerability affects both GitLab Community Edition (CE) and Enterprise Edition (EE) deployments. GitLab security teams have already invalidated potentially compromised session tokens, and a thorough audit of recent access logs is recommended to all self-managed instance administrators.

Alongside the security fix, 18.1.2 includes several important bug fixes to enhance performance and system integrity, covering Git storage management and webhook processing in high-load environments. Full details can be found in the official release post.
