Advisory
Source description from Wordfence Intelligence, credited to Wordfence PRISM.
The Modula plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'items' parameter in versions up to, and including, 3.0.17 This is due to insufficient input sanitization of the per-image 'link' field in the save_merged_items() REST handler and Images\Adapter::normalize_item_row(), which preserves unknown keys verbatim, combined with output escaping in Modula_Helper::generate_attributes() that applies only esc_attr() to the resulting anchor href and does not strip the 'javascript:' URL scheme. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page and clicks the gallery tile.
