Description

wallabag was discovered to contain a Cross-Site Request Forgery (CSRF) which allows attackers to arbitrarily reset annotations, entries and tags, by the GET request to /reset/annotations, /reset/entries, /reset/tags, /reset/archived.

This vulnerability has a CVSSv3.1 score of 4.3.

You should immediately patch your instance to version 2.6.3 or higher if you have more than one user and/or having open registration.

Resolution

These actions are now doable only via POST method, which ensures that we can't do them via a 3rd-party website.
