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."}], "lastModified": "2026-02-09T16:08:55.263", "sourceIdentifier": "security-advisories@github.com"}
