CVE-2025-27408Public exploitNetwork attack vector

Password recovery via unsalted deterministic SHA3 hashes

Published Feb 28, 2025 · Updated Mar 4, 2025

Weak password hashing in Manifest before 4.9.2 allows attackers with database access to recover user passwords through offline cracking. The signup path stores SHA3(password) directly without a unique salt, so equal passwords produce identical hashes suitable for precomputed attacks. Database read access is required; successful cracking exposes credentials and enables account compromise without directly interrupting service.
