Description

Masa CMS is a content management system forked from Mura CMS. In versions 7.5.2 and earlier, the cTrash.empty function does not validate anti-CSRF tokens for trash management requests. An attacker can induce a logged-in administrator to submit a forged request that empties the trash and permanently deletes all deleted content. This can cause irreversible data loss and disrupt recovery of content intended for restoration. This issue has been fixed in versions 7.2.10, 7.3.15, 7.4.10, and 7.5.3. As a workaround, restrict access to the administrative backend, use browser isolation for administrative sessions, and maintain current database backups to recover from unauthorized deletion.
