CVE-2024-5021Network attack vector

Unauthenticated internal-service access via unchecked URL retrieval

Published Jun 19, 2024 · Updated Apr 8, 2026

Server-side request forgery in Nimble3 Nimble Portfolio 3.0.1 and earlier allows remote attackers to reach internal services. The unauthenticated includes/prettyphoto/download-image.php endpoint passes an attacker-controlled URL to PHP's file_get_contents function without destination validation. Exposure requires a network-reachable WordPress installation with the plugin enabled, and the resulting server-originated requests can read or modify data exposed by internal services.
