Detailsinfo

A vulnerability has been found in bplugins Document Embedder Plugin up to 2.4.0 and classified as problematic. This vulnerability affects the function can_read_document of the component Ajax Fallback Path. The manipulation of the argument content/docId with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. As an impact it is known to affect integrity. CVE summarizes:

The Document Embedder – let visitors read files without downloading plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'content (post_content containing block JSON documentSource.doc)' parameter in all versions up to, and including, 2.4.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is triggered specifically when the victim clicks the embedded document's Download button, which causes the de_track_download AJAX fallback path to programmatically create an anchor with the attacker-controlled href and call .click() — a condition reached because supplying docId=0 causes can_read_document() to return false, bypassing the normal download flow.

The advisory is shared for download at wordfence.com. This vulnerability was named CVE-2026-109370 since 10/12/2026. The exploitation appears to be easy. The attack can be initiated remotely.
