CVE-2025-52993 is a race condition vulnerability in Nix, Lix, and Guix package managers that allows an attacker to change the ownership of arbitrary files to the build user's UID and GID. This affects specific versions of Nix (before 2.24.15, 2.26.4, 2.28.4, 2.29.1), Lix (before 2.91.2, 2.92.2, 2.93.1), and Guix (before 1.4.0-38.0e79d5b). Rated Medium severity (CVSS 5.6), the vulnerability has a local attack vector with high attack complexity, potentially leading to low impacts on confidentiality, integrity, and availability. The EPSS score is very low, suggesting a low probability of exploitation. There is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage are minimal, with only one article mentioning fixes for related Lix CVEs.
