The manipulation with an unknown input leads to a cross-site request forgery vulnerability. Using CWE to declare the problem leads to CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. Impacted is integrity. The summary by CVE is:

Masa CMS is a content management system forked from Mura CMS. In versions 7.5.2 and earlier, the cUsers.updateAddress function does not properly validate anti-CSRF tokens for user address management operations. An attacker can induce a logged-in administrator to submit a forged request that adds, modifies, or deletes user address records, including email addresses and phone numbers. This can be used to alter contact information, redirect organizational communications, and corrupt address data in the user directory. 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, or deploy filtering rules to block forged requests to the affected endpoint
