Technical details
The plugin fails to sanitize a user-supplied value before concatenating it into a shortcode string passed to WordPress's shortcode parser via the load_gallery_collection REST route. This content injection vulnerability (CWE-345) allows unauthenticated attackers to execute arbitrary registered shortcodes and disclose non-public gallery content through a network-accessible endpoint.
