CVE-2026-90562

LangBot before 4.10.11 Authentication Bypass via Weak Recovery Key

LangBot before 4.10.11 generates password recovery keys with only 24 bits of entropy and applies no rate limiting to the unauthenticated reset-password endpoint. Remote attackers knowing the administrator email can exhaust the keyspace through concurrent requests to reset the admin password and gain account access.
