27 Jun 2025 — The Nix, Lix, and Guix package managers allow a bypass of build isolation in which a user can elevate their privileges to the build user account (e.g., nixbld or guixbuild). This affects Nix through 2.24.15, 2.26.4, 2.28.4, and 2.29.1; Lix through 2.91.2, 2.92.2, and 2.93.1; and Guix before 1.4.0-38.0e79d5b. • https://discourse.nixos.org/t/security-advisory-privilege-escalations-in-nix-lix-and-guix/66017 • CWE-282: Improper Ownership Management •

27 Jun 2025 — 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. This affects Nix before 2.24.15, 2.26.4, 2.28.4, and 2.29.1; Lix before 2.91.2, 2.92.2, and 2.93.1; and Guix before 1.4.0-38.0e79d5b. • https://discourse.nixos.org/t/security-advisory-privilege-escalations-in-nix-lix-and-guix/66017 • CWE-276: Incorrect Default Permissions •

27 Jun 2025 — The Nix, Lix, and Guix package managers fail to properly set permissions when a derivation build fails. This may allow arbitrary processes to modify the content of a store outside of the build sandbox. This affects Nix before 2.24.15, 2.26.4, 2.28.4, and 2.29.1; Lix before 2.91.2, 2.92.2, and 2.93.1; and Guix before 1.4.0-38.0e79d5b. • https://discourse.nixos.org/t/security-advisory-privilege-escalations-in-nix-lix-and-guix/66017 • CWE-732: Incorrect Permission Assignment for Critical Resource •

27 Jun 2025 — A race condition in the Nix, Lix, and Guix package managers enables changing the ownership of arbitrary files to the UID and GID of the build user (e.g., nixbld* or guixbuild*). This affects Nix before 2.24.15, 2.26.4, 2.28.4, and 2.29.1; Lix before 2.91.2, 2.92.2, and 2.93.1; and Guix before 1.4.0-38.0e79d5b. • https://discourse.nixos.org/t/security-advisory-privilege-escalations-in-nix-lix-and-guix/66017 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
