Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition, where the product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. In WWBN/AVideo, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

CVE-2026-43884 fix `603e7bf` patched `EpgParser.php` and `plugin/AI/receiveAsync.json.php` to use `url_get_contents` (redirect-safe). Neither uses the `$resolvedIP` out-param of `isSSRFSafeURL()` for DNS pinning via `CURLOPT_RESOLVE`. Six+ other call sites still discard `$resolvedIP`, opening DNS-rebinding TOCTOU. Reference correct pattern at `plugin/YPTWallet/YPTWallet.php:1071-1098`: ```php $resolvedIP = null; if (isSSRFSafeURL($url, $resolvedIP)) { curl_setopt($ch, CURLOPT_RESOLVE, ["$h
