What is CVE-2026-40325?
CVE-2026-40325 is a high-severity vulnerability in MasaCMS, published on 6 May 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
Masa CMS is a content management system forked from Mura CMS. In versions 7.5.2 and earlier, the `cTrash.restore` function does not properly validate anti-CSRF tokens for content restoration requests. An attacker can trick a logged-in administrator to submit a forged request that restores deleted items from the trash and places them at an attacker-controlled location in the site structure through the parentid parameter. This can restore previously deleted malicious or outdated content, expose sensitive documents by moving them into publicly accessible locations, and disrupt site structure or content integrity.
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 regularly empty the trash to reduce the amount of content available for unauthorized restoration.
Weakness: CWE-352
