electerm's encrypt method not safe enough

  • Disclosed: 14.05.2026
  • Updated: 11.10.2026 10:22

Impact

Insecure sync encryption: deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC leads to confidentiality and integrity failures for synced bookmark/profile data. Attackers can crack common passwords across installs and perform undetected ciphertext bit-flips to alter config/bookmarks.
