Drupal Actstream: Incorrect authorization in account configuration route
Drupal Actstream, a contributed module that aggregates external activity such as RSS feeds, has an incorrect authorization flaw in a configuration route. The route does not sufficiently check that the user editing it is the account owner or a user administrator. An attacker with a site account may be able to edit accounts they should not, which could enable account takeover or privilege changes. Only sites with Actstream installed are affected. The CVE text describes the issue as forceful browsing, but the Drupal advisory describes a missing ownership check, and this entry follows the advisory.
