HelloAsso <= 1.1.10 - Missing Authorization to Authenticated (Contributor+) Limited Options Update
The HelloAsso plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'ha_ajax' function in all versions up to, and including, 1.1.10. This makes it possible for authenticated attackers, with Contributor-level access and above, to update plugin options, potentially disrupting the service.
