Detailsinfo

A vulnerability classified as problematic has been found in mwtcmi Frogman up to 1.6.5. Affected is the function formatMarkdown of the file assets/js/chat.js of the component Chat Console Markdown Formatter. The manipulation of the argument extension names/ring-group descriptions/IVR names/queue descriptions with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as 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. This is going to have an impact on integrity. CVE summarizes:

Frogman provides headless FreePBX control. Prior to version 1.6.6, Frogman's chat-console markdown formatter (`assets/js/chat.js`'s `formatMarkdown`) inserted regex capture groups as raw HTML in four template patterns: inline code, bold, markdown links, and download links. Tool responses that reflect user-controlled fields — extension names, ring-group descriptions, IVR names, queue descriptions, etc. — could carry an HTML/JavaScript payload that executes when another admin views the response through Frogman chat. The payload runs in the viewer's session, with the viewer's permissions. FreePBX's own admin GUI escapes these same fields via `freepbx_htmlspecialchars()` throughout its view templates. The chat formatter was the leaky side. Version 1.6.6 patches the issue.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-46516 since 05/14/2026. The exploitability is told to be easy. It is possible to launch the attack remotely.
