The 'Portfolio – Filterable Masonry Portfolio Gallery for Professionals' WordPress plugin versions up to 1.2.2 contain a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input in the 'portfolio-pro' shortcode. Authenticated attackers with contributor or higher privileges can inject malicious scripts that execute in the context of users viewing the injected pages. This vulnerability allows limited impact on confidentiality and integrity but does not affect availability. No known exploits are reported in the wild, and no patch or official fix has been published yet.

Successful exploitation allows an authenticated user 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 partial compromise of user confidentiality and integrity, such as session hijacking or unauthorized actions performed on behalf of other users. The vulnerability does not impact system availability. There are no known active exploits reported at this time.

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 removing the vulnerable plugin to prevent exploitation. Monitor for updates from the vendor or WordPress plugin repository for a security patch.
