Detection & IOCsextracted from sources · hover to see the quote

→The attack vector is a maliciously crafted playlist file injected with JavaScript/HTML code; inspect playlist files (e.g., .m3u, .pls, .xspf) ingested by Kodi for embedded script tags or JavaScript URIs. ↗
→The XSS payload executes in the victim's browser context when the playlist is rendered; monitor Kodi's web interface HTTP responses for reflected/stored script content originating from playlist data. ↗
→Affected versions are Kodi 17.6 and below; flag any Kodi instance running version <= 17.6 as vulnerable to this persistent XSS via playlist. ↗

·The vulnerability is exploitable via the playlist feature specifically; the fix was tracked upstream at the referenced ticket — ensure patched builds are deployed. ↗
·Scope is listed as local, meaning the attacker likely needs the ability to supply or modify a playlist accessible to the victim's Kodi instance. ↗
