CVE-2026-33648 — AVideo Vulnerable to OS Command Injection via Unsanitized `users_id` and `liveTransmitionHistory_id` in Restreamer Log File Path

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the restreamer endpoint constructs a log file path by embedding user-controlled `users_id` and `liveTransmitionHistory_id` values from the JSON request body without any sanitization. This log file path is then concatenated directly into shell commands passed to `exec()`, allowing an authenticated user to achieve arbitrary command execution on the server via shell metacharacters such as `$()` or backticks. Commit 99b865413172045fef6a98b5e9bfc7b24da11678 contains a patch.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.9% (30-day exploitation probability)+9
Technical severity (high)+6
CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

What should defenders know first?

CVE-2026-33648 is "AVideo Vulnerable to OS Command Injection via Unsanitized `users_id` and `liveTransmitionHistory_id` in Restreamer Log File Path", rated High. It affects Avideo (Wwbn); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 8.8 describes technical severity. EPSS 0.92% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
