Description
The GreenShift – Animation and Page Builder Blocks plugin for WordPress is vulnerable to unauthorized modification of data in versions up to, and including, 12.8.9. This is due to a missing capability check on the 'gspb_update_global_wp_settings' function that only verifies the 'edit_posts' capability instead of requiring administrative privileges. This makes it possible for authenticated attackers, with contributor-level access and above, to modify global WordPress theme color settings site-wide, leading to site defacement.
