Bulwark Webmail is a self-hosted webmail client for Stalwart Mail Server. Prior to version 1.4.10, the GET /api/auth/session endpoint previously included the user's plaintext password in the JSON response. This exposed credentials to browser logs, local caches, and network proxie. This issue has been patched in version 1.4.10.
