CVE-2025-52991 is a low-severity vulnerability rated 3.2/10 on the CVSS scale. The Nix, Lix, and Guix package managers default to using temporary build directories in a world-readable and world-writable location. This allows standard users to deceive the package manager into using directories with pre-existing content, potentially leading to unauthorized actions or data manipulation. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
