Prior to 1.35.3, a regular organization member can retrieve all ciphers within an organization, regardless of collection permissions. The endpoint /ciphers/organization-details is accessible to any organization member and internally uses Cipher::find_by_org to retrieve all ciphers. These ciphers are returned with CipherSyncType::Organization without enforcing collection-level access control. This vulnerability is fixed in 1.35.3."}], "lastModified": "2026-02-13T21:41:01.003", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:dani-garcia:vaultwarden:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "79A968D5-FAC8-49BF-8FA6-8F54218D1875", "versionEndExcluding": "1.35.3"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
