Summary
A cross-site scripting vulnerability has been found in Pluck CMS up to version 4.7.21 in the Albums module. The htmlspecialchars_decode function in data/modules/albums/albums.admin.php mishandles the Info argument, allowing remote injection of malicious scripts. The exploit is public, and the project has not responded to the report.
