Description
The Token Authentication module provides a token for use in the URL to authenticate users to a site.
Under certain uncommon situations, the module may not revert a user's session properly. Depending on how tokenauth is used, this could result in subsequent requests being performed as a user with additional privileges when they shouldn't.
CVE: CVE-2012-2720
Versions affected
- Tokenauth 6.x-1.x versions prior to 6.x-1.7.
Drupal core is not affected. If you do not use the contributed Token Authentication module, there is nothing you need to do.
Solution
Install the latest version:
- If you use the Tokenauth module for Drupal 6.x, upgrade to Tokenauth 6.x-1.7
Also see the Tokenauth project page.
