Details

CSRF can expose users authentication token ### Issue The /login and /change endpoints can return the authenticated user's authentication token in response to a GET request. Since GET requests aren't protected with a CSRF token, this could lead to a malicious 3rd party site acquiring the authentication token. ### Patches Version 3.4.5 and soon to be released 4.0.0 are patched. ### Workarounds If you aren't using authentication tokens - you can set the SECURITY_TOKEN_MAX_AGE to "0" (seconds) which should make the token unusable. ### References None
