EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 4.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 63% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
