# CVE-2026-33502: AVideo has Unauthenticated SSRF via plugin/Live/test.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 0.4% , percentile 38: FIRST’s model estimates a 0.4% chance of exploitation activity in the next 30 days, higher than 38% 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, an unauthenticated server-side request forgery vulnerability in plugin/Live/test.php allows any remote user to make the AVideo server send HTTP requests to arbitrary URLs. This can be used to probe localhost/internal services and, when reachable, access internal HTTP resources or cloud metadata endpoints. Commit 1e6cf03e93b5a5318204b010ea28440b0d9a5ab3 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: 9.3 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N`
- GitHub CVSS 3.1: 9.3 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 0.45% probability of exploitation activity in the next 30 days; percentile 38.
