CVE-2026-7640 is a stored cross-site scripting vulnerability in the WP Customer Area plugin for WordPress. The issue exists in the handling of the 'type' attribute of the customer-area-protected-content shortcode, where input is not properly sanitized or escaped. Authenticated attackers with Contributor-level privileges or higher can exploit this to inject arbitrary scripts that execute in the context of users viewing the injected content. This vulnerability affects all plugin versions up to and including 8.3.5. The CVSS 3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and privileges required at the contributor level. There is no vendor advisory or patch information currently available, and no known exploits in the wild have been reported.

Successful exploitation allows authenticated users with Contributor-level access or above to inject and execute arbitrary JavaScript in the context of other users viewing the affected pages. This can lead to information disclosure and integrity impacts, such as session hijacking or unauthorized actions performed on behalf of users. There is no direct availability impact reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the vulnerable shortcode. Monitor vendor communications for updates and apply patches promptly once released.
