# CVE-2026-28502: AVideo has Authenticated Remote Code Execution via Unsafe Plugin ZIP Extraction

**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?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 1.0% , percentile 64: FIRST’s model estimates a 1.0% chance of exploitation activity in the next 30 days, higher than 64% of all scored CVEs (moderate). 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)) < 21.0, no fixed version listed . Check your lockfile, including transitive dependencies.

## What it is

WWBN AVideo is an open source video platform. Prior to version 24.0, an authenticated Remote Code Execution (RCE) vulnerability was identified in AVideo related to the plugin upload/import functionality. The issue allowed an authenticated administrator to upload a specially crafted ZIP archive containing executable server-side files. Due to insufficient validation of extracted file contents, the archive was extracted directly into a web-accessible plugin directory, allowing arbitrary PHP code execution. This issue has been patched in version 24.0.

## Affected packages

- Composer (PHP) `wwbn/avideo` < 21.0 → fixed: none listed

## Affected products (CVE record)

- WWBN AVideo: < 24.0

## Severity

- GitHub_M CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N`
- GitHub CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.04% probability of exploitation activity in the next 30 days; percentile 64.
