# CVE-2026-33716: AVideo Allows Unauthenticated Live Stream Control via Token Verification URL Override in control.json.php

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.6% , percentile 48: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 48% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes wwbn/avideo (Composer (PHP)) <= 26.0, no fixed version listed . Check your lockfile, including transitive dependencies.

## What it is

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the standalone live stream control endpoint at plugin/Live/standAloneFiles/control.json.php accepts a user-supplied streamerURL parameter that overrides where the server sends token verification requests. An attacker can redirect token verification to a server they control that always returns {"error": false}, completely bypassing authentication. This grants unauthenticated control over any live stream on the platform, including dropping active publishers, starting/stopping recordings, and probing stream existence. Commit 388fcd57dbd16f6cb3ebcdf1d08cf2b929941128 contains a patch.

## Affected packages

- Composer (PHP) `wwbn/avideo` <= 26.0 → fixed: none listed

## Affected products (CVE record)

- WWBN AVideo: <= 26.0

## Severity

- GitHub_M CVSS 3.1: 9.4 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H`
- GitHub CVSS 3.1: 9.4 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.60% probability of exploitation activity in the next 30 days; percentile 48.
