8.1 HIGH

Network-reachable with no auth or UI (PR:N/UI:N), but forging a valid encrypted payload raises complexity to AC:H; unescaped shell exec yields full C:H/I:H/A:H on the host.

DescriptionCVE.org

AVideo through 29.0 contains an OS command injection vulnerability in the ffmpeg.json.php endpoint where notifyCode and callback parameters are concatenated into a shell command without escaping. Attackers who can craft a valid encrypted payload can inject arbitrary shell metacharacters into these fields to execute OS commands as the web-server user.

News Critical OS Command Injection in WWBN AVideo ≤29.0 - CVE-2026-63305 Jul 17, 2026

AnalysisAI

OS command injection in WWBN AVideo through version 29.0 allows attackers to execute arbitrary operating-system commands as the web-server user via the ffmpeg.json.php endpoint. The notifyCode and callback request parameters are concatenated into a shell command without escaping, so an attacker able to produce a valid encrypted payload can inject shell metacharacters and achieve remote code execution. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to craft a VALID ENCRYPTED PAYLOAD accepted by the ffmpeg.json.php endpoint, then embed shell metacharacters (e.g. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals point to a genuinely high-severity flaw but with a meaningful exploitation barrier. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has reverse-engineered or otherwise obtained the ability to produce a valid encrypted payload sends a crafted request to ffmpeg.json.php with shell metacharacters embedded in the notifyCode or callback parameter, e.g. a value containing $(...) or a semicolon-chained command. …
Remediation Patch available per vendor advisory GHSA-g9x9-q7qj-6mv5 (https://github.com/WWBN/AVideo/security/advisories/GHSA-g9x9-q7qj-6mv5); upgrade to the fixed release referenced there, as an exact fixed version is not stated in the available data - confirm the target version directly from the advisory and the AVideo GitHub releases before deploying. … Detailed patch versions, workarounds, and compensating controls in full report.
