CVE-2026-33502

AVideo has Unauthenticated SSRF via plugin/Live/test.php

This is an unauthenticated SSRF vulnerability affecting any deployment that exposes plugin/Live/test.php.

An attacker can:

• probe localhost and internal network services
• distinguish open and closed ports
• target cloud metadata endpoints if reachable
• retrieve reflected content from internal HTTP services when the upstream responds with a body

The server and the internal network reachable from it are impacted. No unauthenticated code execution was validated from this issue on the tested environment.

Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside. Typical impact: access to internal metadata services, internal APIs, or cloud credentials.

CVE-2026-33502 has a CVSS score of 9.3 (Critical). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

Kodem intelligence

The safest fix is to remove plugin/Live/test.php from production deployments.

If it must remain:

• require admin authentication
• only allow requests to explicitly configured Live stats URLs
• block localhost, RFC1918, link-local, and metadata IP ranges
• stop reflecting fetched bodies and raw upstream errors to the client

Minimal hardening example:

require_once dirname(__FILE__) . '/../../videos/configuration.php';

if (!User::isAdmin()) {
    http_response_code(403);
    exit('Forbidden');
}

$statsURL = $_REQUEST['statsURL'] ?? '';
if (empty($statsURL) || !isSSRFSafeURL($statsURL)) {
    exit('Unsafe URL');
}

1. What is CVE-2026-33502? CVE-2026-33502 is a critical-severity server-side request forgery (SSRF) vulnerability in wwbn/avideo (composer), affecting versions <= 26.0. No fixed version is listed yet. Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside.
2. How severe is CVE-2026-33502? CVE-2026-33502 has a CVSS score of 9.3 (Critical). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of wwbn/avideo are affected by CVE-2026-33502? wwbn/avideo (composer) versions <= 26.0 is affected.
4. Is there a fix for CVE-2026-33502? No fixed version is listed for CVE-2026-33502 yet. Monitor the advisory for updates and apply mitigations in the interim.
5. Is CVE-2026-33502 exploitable, and should I be worried? Whether CVE-2026-33502 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-33502 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2026-33502? No fixed version is listed yet. In the interim: Validate and restrict destination URLs against an allowlist. Block requests to private IP ranges and cloud metadata endpoints.
