CVE-2026-43884 Details
Description
WWBN AVideo is an open source video platform. In versions up to and including 29.0, two endpoints (plugin/AI/receiveAsync.json.php and objects/EpgParser.php) in AVideo call isSSRFSafeURL() to validate user-supplied URLs, then fetch them using bare file_get_contents() without disabling PHP's automatic redirect following. An attacker can supply a URL pointing to a server they control that returns a 302 redirect to an internal/cloud-metadata address (e.g., http://169.254.169.254/latest/meta-data/). Since isSSRFSafeURL() only validates the initial URL, the redirect target bypasses all SSRF protections. Commit 603e7bf77a835584387327e35560262feb075db3 contains an updated fix.
A server-side request forgery (SSRF) vulnerability has been identified in WWBN AVideo versions through 29.0. The issue arises in two endpoints, 'plugin/AI/receiveAsync.json.php' and 'objects/EpgParser.php', which use the 'isSSRFSafeURL()' function to validate user-provided URLs. However, these endpoints then retrieve the URLs using 'file_get_contents()'' without disabling PHP's automatic redirect feature. This allows an attacker to redirect to internal metadata services, bypassing SSRF protections. Additionally, some calls to 'isSSRFSafeURL()' neglect to use a DNS pinning feature, leaving them open to DNS rebinding attacks.
Users can update to the latest version of AVideo, where this vulnerability has been patched. Instructions for updating can be found in the AVideo documentation.
