CVE-2026-43884: CWE-918: Server-Side Request Forgery (SSRF) in WWBN AVideo
CVE-2026-43884 is a Server-Side Request Forgery (SSRF) vulnerability in WWBN AVideo versions up to and including 29. 0. The vulnerability arises because two endpoints validate user-supplied URLs but then fetch them using PHP's file_get_contents() without disabling automatic redirect following. This allows an attacker to supply a URL that redirects to internal or cloud metadata addresses, bypassing SSRF protections. The vulnerability has a CVSS score of 7. 7, indicating high severity. A code commit (603e7bf77a835584387327e35560262feb075db3) contains a fix, but no official patch or vendor advisory is currently provided. No known exploits are reported in the wild.
AI Analysis
Technical Summary
WWBN AVideo versions up to 29.0 contain an SSRF vulnerability (CWE-918) in two endpoints: plugin/AI/receiveAsync.json.php and objects/EpgParser.php. These endpoints use isSSRFSafeURL() to validate URLs but then fetch the URLs with PHP's file_get_contents() without disabling automatic HTTP redirect following. An attacker can supply a URL that initially passes validation but redirects (via HTTP 302) to internal or cloud metadata service addresses (e.g., 169.254.169.254), bypassing SSRF protections. This can lead to unauthorized access to sensitive internal resources. A code commit has been made to fix this issue, but no official patch or advisory is currently documented.
Potential Impact
Successful exploitation allows an attacker with at least low privileges to induce the server to make HTTP requests to internal or cloud metadata endpoints, potentially exposing sensitive information such as cloud instance metadata. The vulnerability does not impact integrity or availability but has high confidentiality impact. There are no known public exploits at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. A code commit addressing the issue exists, indicating a fix is available in the source repository. Until an official patch is released, users should avoid exposing the vulnerable endpoints to untrusted users or implement network-level restrictions to prevent SSRF exploitation via redirects.
