Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Concrete CMS (Packagist package concrete5/concrete5) versions from 9.0.0RC1 before 9.5.1 are vulnerable to cross-site request forgery in the bulk log deletion dialog. An attacker would need to get a logged-in user to visit a malicious page, which could then trigger deletion of logs. The source gives few details beyond this. Upgrade to version 9.5.1, which is listed as the fixed release.
