Summary

WWBN AVideo up to version 26.0 allows an authenticated uploader to bypass SSRF validation via controlled downloadURL values with extensions .mp4, .mp3, .zip, .jpg, .png, .gif, .webm. The server fetches and stores the response as media, enabling SSRF response exfiltration.

Risk Assessment

An authenticated attacker can use the server to scan internal resources and exfiltrate data from SSRF responses.

Recommendation

Apply the fix for CVE-2026-27732 and upgrade AVideo to the latest version.

Original NVD description (English source)

WWBN AVideo is an open source video platform. In versions 26.0 and prior, objects/aVideoEncoder.json.php still allows attacker-controlled downloadURL values with common media or archive extensions such as .mp4, .mp3, .zip, .jpg, .png, .gif, and .webm to bypass SSRF validation. The server then fetches the response and stores it as media content. This allows an authenticated uploader to turn the upload-by-URL flow into a reliable SSRF response-exfiltration primitive. The vulnerability is caused by an incomplete fix for CVE-2026-27732.
