Description

Admidio from 5.0.0 before 5.0.16 contains an insecure direct object reference vulnerability in ForumService::saveTopic() that allows authenticated members to modify other users' forum topics. Attackers can replace the topic_uuid parameter in their own topic_save request, reusing their CSRF token, to overwrite the victim topic's title and first post.
