The wp_http_validate_url function in wp-includes/http.php in WordPress before 4.4.2 allows remote attackers to conduct server-side request forgery (SSRF) attacks via a zero value in the first octet of an IPv4 address in the u parameter to wp-admin/press-this.php.

Security readout for executives and security teams

WordPress versions before 4.4.2 had an SSRF flaw that could let a remote attacker make the server send unintended requests. The issue involved URL validation for the Press This endpoint. Business urgency is highest for legacy WordPress sites or packaged deployments still below 4.4.2. Exposure is mainly older WordPress installations before 4.4.2, including distribution-packaged WordPress noted by Debian. Modern maintained WordPress deployments should not be affected if security updates were applied. Prioritize as moderate unless an internet-facing legacy WordPress site is found. The fix is old and available, so unresolved exposure indicates weak patch governance and may enable internal network reachability through SSRF. Mitigation focus: Upgrade WordPress to 4.4.2 or later.; Apply relevant vendor or distribution WordPress security updates.; Check Debian advisory guidance for Debian-packaged WordPress..
