Data disclosure and tampering via deterministic encryption
Published May 28, 2026 · Updated May 28, 2026
Weak encryption in electerm before 3.9.5 allows remote authenticated users to read and alter bookmark and profile data via synced ciphertext. The encrypt and encryptAsync functions in src/app/lib/enc.js derive AES-192-CBC keys with the constant salt "salt," reuse an all-zero IV, and produce ciphertext without an authentication tag. Exploitation requires low-privileged access to synced ciphertext; common passwords can be tested across installations, and ciphertext bit flips alter stored configuration without detection.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
