A vulnerability in Bulwark Webmail, prior to version 1.4.10, allowed the GET /api/auth/session endpoint to return the user's plaintext password in the JSON response. This issue exposed credentials to browser logs, local caches, and network proxies. The vulnerability has been patched in version 1.4.10, which now only returns the server URL and username, while session credentials have been moved to a new PUT handler that is protected to prevent cross-origin and unauthorized CLI access.
Users can upgrade to Bulwark Webmail version 1.4.10 or later to address this vulnerability.
