High (8.6) in wwbn avideo. EPSS 0.4% estimated probability of exploitation activity in the next 30 days.
WWBN AVideo through 29.7.1 contains a missing authorization vulnerability in Live plugin restream endpoints that allows authenticated streamers to obtain other users' stream keys by supplying arbitrary live_transmitions_history_id values. Attackers can redeem the issued action tokens at verifyTokenForAction.json.php to retrieve victims' HLS URLs and stream keys, then publish as the victim or restream private or pay-per-view lives.

Explain CVE-2026-126541 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-126541?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-126541?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-126541 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
