The CVE-2025-XXXXX vulnerability in ssrfcheck arises due to an incomplete IP address deny list, specifically excluding the multicast range 224.0.0.0/4. Attackers can exploit this by sending crafted requests to internal multicast addresses, bypassing intended restrictions. SSRF occurs when the application processes these malicious requests, allowing unauthorized access to internal services or data. The vulnerability stems from improper validation of reserved IP ranges, enabling attackers to probe or interact with unintended network endpoints.
