CVE-2022-4610Public exploit

Stored-password disclosure via recoverable server-side key

Published Dec 19, 2022 · Updated Apr 15, 2025

Server-side cryptography in Click Studios Passwordstate and its Chrome extension allows local users to recover all stored passwords. The server derives its AES database key from secrets retained with the deployment, and builds from 8903 merely reverse the recovered key. Access to the web configuration, database secrets, and Passwordstate database is required; the public decryptor then returns plaintext credentials.
