CVE-2026-39860 is a critical vulnerability in the Nix package manager affecting Linux sandboxed builds. It arises from a flaw in the fix for a previous vulnerability (CVE-2024-27297) that allows arbitrary file overwrites by following symbolic links during fixed-output derivation output registration. This can be exploited by users who can submit builds to the Nix daemon, potentially leading to root privilege escalation by overwriting sensitive files. The issue does not affect sandboxed macOS builds. Multiple versions of Nix prior to specific fixed releases are vulnerable. The vulnerability has a CVSS score of 9. A fix is available in Nix versions 2.28.6, 2.29. Join the discussion | CVE Database V5 | 04/08/2026, 20:58:22 UTC Added: 04/08/2026, 21:05:48 UTC |
