    GHSA-hh7m-rx4f-4vpv

    HIGHCVE-2021-21241
    // 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 SECURITYTOKENMAXAGE to "0" (seconds) which should make the token unusable.
