{"id":"CVE-2025-68621","summary":"Trilium Notes has a Timing Attack Vulnerability in /api/login/sync","details":"Trilium Notes is an open-source, cross-platform hierarchical note taking application with focus on building large personal knowledge bases.  Prior to 0.101.0, a critical timing attack vulnerability in Trilium's sync authentication endpoint allows unauthenticated remote attackers to recover HMAC authentication hashes byte-by-byte through statistical timing analysis. This enables complete authentication bypass without password knowledge, granting full read/write access to victim's knowledge base. This vulnerability is fixed in 0.101.0.","aliases":["GHSA-hxf6-58cx-qq3x"],"modified":"2026-08-12T03:51:08.514943512Z","published":"2026-02-06T21:21:19.308Z","database_specific":{"cwe_ids":["CWE-208"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68621.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68621.json"},{"type":"ADVISORY","url":"https://github.com/TriliumNext/Trilium/security/advisories/GHSA-hxf6-58cx-qq3x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68621"},{"type":"FIX","url":"https://github.com/TriliumNext/Trilium/pull/8129"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/triliumnext/trilium","events":[{"introduced":"0"},{"fixed":"2d486c9934925296d39d3fc4046e77f750e2c146"}],"database_specific":{"cpe":"cpe:2.3:a:triliumnotes:trilium:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"0.101.0"}],"source":["AFFECTED_FIELD","CPE_RANGE"]}}],"versions":["v0.99.4","v0.99.2","v0.99.0","v0.98.1","v0.98.0","v0.97.0","v0.97.2","v0.96.0","v0.63.6","v0.62.2","v0.62.1-beta","v0.62.0-beta","v0.61.4-beta","v0.61.3-beta","v0.61.2-beta","v0.61.1-beta","v0.61.0-beta","v0.59.1","v0.59.0-beta","v0.58.0-beta","v0.57.3","v0.57.2","v0.57.1-beta","v0.57.0-beta","v0.56.1","v0.56.0-beta","v0.55.1","v0.55.0-beta","v0.54.1-beta","v0.54.0-beta","v0.53.2","v0.53.1-beta","v0.53.0-beta","v0.52.2","v0.52.1-beta","v0.52.0-beta","v0.51.2","v0.51.1-beta","v0.51.0-beta","v0.50.1","v0.50.0-beta","v0.49.4","v0.49.3","v0.49.2-beta","v0.49.1-beta","v0.49.0-beta","v0.48.6.1","v0.48.6-docker","v0.48.6","v0.48.5","v0.48.4","v0.48.3","v0.48.2","v0.48.1-beta","v0.48.0-beta","v0.47.0-beta","v0.46.3-beta","v0.46.2-beta","v0.46.1-beta","v0.46.0-beta","v0.44.4","v0.44.3-beta","v0.44.2-beta","v0.44.1-beta","v0.44.0-beta","v0.42.1","v0.42.0-beta","v0.41.6","v0.41.5","v0.41.4-beta","v0.41.3-beta","0.41.3","v0.41.2-beta","v0.41.1-beta","v0.41.0-beta","v0.40.0-beta","v0.39.3","v0.39.2-beta","v0.39.1-beta","v0.39.0-beta","v0.38.2","v0.38.1-beta","v0.38.0-beta","v0.37.2","v0.37.1-beta","v0.37.0-beta","v0.36.1-beta","v0.36.0-beta","v0.35.1","v0.35.0-beta","v0.34.1","v0.34.0-beta","v0.33.3","v0.33.2-beta","v0.33.1-beta","v0.33.0-beta","v0.32.3","v0.32.2-beta","v0.32.1-beta","v0.32.0-beta","v0.31.3","v0.31.2-beta","v0.31.1-beta","v0.31.0-beta","v0.30.3-beta","v0.30.2-beta","v0.30.1-beta","v0.30.0-beta","v0.29.1","v0.29.0-beta","v0.28.3","v0.28.2","v0.28.1-beta","v0.28.0-beta","v0.27.4","v0.27.3","v0.27.2-beta","v0.27.1-beta","v0.27.0-beta","v0.26.1","v0.26.0-beta","v0.25.1-beta","v0.25.0-beta","v0.24.5","v0.24.4-beta","v0.24.3-beta","v0.24.2-beta","v0.24.1-beta","v0.24.0-beta","v0.23.0","v0.22.1","v0.22.0","v0.21.0","v0.20.2","v0.20.1","v0.20.0","v0.19.1","v0.19.0","v0.18.0","v0.17.0","v0.16.0","v0.15.0","v0.14.1","v0.14.0","v0.13.0-beta","v0.11.1","v0.11.0-beta","v0.10.2-beta","v0.10.1-beta","v0.10.0-beta","v0.8.1","v0.8.0-beta","v0.7.0-beta","v0.6.1","v0.6.0-beta","v0.5.5-beta","v0.5.4-beta","v0.5.3-beta","v0.5.2-beta","v0.5.1-beta","v0.5.0-beta","v0.4.1","v0.4.0-beta","v0.3.2","v0.3.1","v0.3.0","v0.2.2","v0.2.1","v0.2.0","v0.1.2","v0.1.1","v0.1.0","v0.0.11","v0.0.10","v0.0.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68621.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
