Risk and Exploitability

With a CVSS score of 9.3 the vulnerability is classified as critical. The EPSS score is not available, but the presence of a persisted payload that triggers in visitors’ browsers suggests high exploitation potential, especially in environments where the canStream role is widely granted.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the official AVideo patch that updates the LiveLinks plugin to remove unsanitized title and description fields; if a patch is not immediately available, check for an updated release that includes the fix.

  • Deploy a Content Security Policy that blocks inline scripts and restricts script sources to the site origin, mitigating any persisted XSS payloads.
