GHSA-HH7M-RX4F-4VPV

Vulnerability from github – Published: 2021-01-11 20:38 – Updated: 2024-09-20 17:48

Summary

CSRF can expose users authentication token

Details

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.

  "details": "The Python \"Flask-Security-Too\" package is used for adding security features to your Flask application. It is an is a independently maintained version of Flask-Security based on the 3.0.0 version of Flask-Security. In Flask-Security-Too from version 3.3.0 and before version 3.4.5, the /login and /change endpoints can return the authenticated user\u0027s authentication token in response to a GET request. Since GET requests aren\u0027t protected with a CSRF token, this could lead to a malicious 3rd party site acquiring the authentication token. Version 3.4.5 and version 4.0.0 are patched. As a workaround, if you aren\u0027t using authentication tokens - you can set the SECURITY_TOKEN_MAX_AGE to \"0\" (seconds) which should make the token unusable.",
