# AVideo Live plugin lets streamers steal other users' stream keys

Link for people: https://infrastack.ai/live/CVE-2026-126541 (this .md is for agents)

The AVideo Live plugin's restream endpoints do not check ownership of live stream records, so any logged-in streamer can request other users' tokens by changing a history ID. The attacker then redeems those tokens at verifyTokenForAction.json.php to get victims' HLS URLs and stream keys and publish as them or restream private and pay-per-view lives.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

## How to check

- Check the AVideo version the site runs; the sources say the flaw affects releases through `29.7.1`.
- Confirm whether the Live plugin is enabled on the site.

## From the sources

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.
