ETK-2026-3392Zero's internal tracking ID, independent of the CVE number.
waiting for further signalsZero needs more public information before it can validate it.description
AVideo versions from 6.5 through at least 30.2 may store unsafe embedded-video links and render them in viewer pages. A user permitted to upload videos can cause script execution in the browser context of people who open the affected video, including administrators. Exploitation requires upload permission and an embedded video link to be viewed.
mitigation
Restrict video-upload and embedded-link creation permissions, and review or disable existing embedded video links until they have been validated. Enforce an allowlist of safe URL schemes when saving and rendering embed links; no fixed wwbn/avideo release is recorded.
outcome
Contextual, not validated: no deterministic check could cover this one, and no technique passed our review.
