CVE-2025-24365: 
NixOS vulnerability analysis and mitigation

CVE-2025-24365 affects vaultwarden, an unofficial Bitwarden compatible server written in Rust (formerly known as bitwarden_rs). The vulnerability allows attackers to obtain owner rights of other organizations within the system. This critical security flaw was discovered in January 2025 and has been assigned a CVSS score of 8.1 (HIGH). The vulnerability affects versions <= 1.32.7 and has been fixed in version 1.33.0 (GitHub Advisory, NVD).

The vulnerability stems from a variable confusion issue in the OrgHeaders trait located in src/auth.rs. The flaw occurs when the server processes organization UUID from both path parameters and GET query values, where the GET query value overwrites the path parameter value. This confusion allows attackers to interact with one organization while having rights of another. The vulnerability is classified as CWE-284 (Improper Access Control) and requires the attacker to know the ID of the victim organization and have owner/admin rights in another organization (GitHub Advisory).

The vulnerability has significant impact potential, allowing attackers to escalate privileges within organizations and potentially access sensitive data. With Vaultwarden's large user base of over 1.5 million downloads and 181 million Docker pulls, the scope of potential impact is substantial. Attackers can gain unauthorized administrative access, modify organization settings, and potentially compromise password management security (Security Online).

The vulnerability has been patched in Vaultwarden version 1.33.0. Organizations using affected versions are strongly advised to update to version 1.33.0 or later immediately. The update includes comprehensive security fixes and improvements to prevent privilege escalation attacks. Organizations should also review their access controls and monitor for any suspicious activity (GitHub Release).
