CVE-2026-40174 Details
Description
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
A cross-site request forgery (CSRF) vulnerability has been identified in Masa CMS versions through 7.5.2, specifically within the user address management feature. The issue arises because the 'cUsers.updateAddress' function does not adequately validate anti-CSRF tokens, allowing attackers to manipulate user address records. This could include adding, modifying, or deleting information such as email addresses and phone numbers. Exploitation of this vulnerability could disrupt organizational communications and corrupt address data in the user directory.
Users are advised to upgrade to Masa CMS versions 7.2.10, 7.3.15, 7.4.10, or 7.5.3. If an immediate upgrade is not possible, restrict access to the administrative backend, use browser isolation for administrative sessions, or deploy filtering rules to block forged requests to the affected endpoint.
