The CVE-2025-XXXXX vulnerability in XXL-JOB (up to version 3.1.1) allows an attacker to perform Server-Side Request Forgery (SSRF) attacks via the `httpJobHandler` function in SampleXxlJob.java. This occurs due to insufficient validation of user-supplied URLs in HTTP job requests. An attacker can exploit this by crafting malicious requests that force the server to make unauthorized internal or external HTTP requests. This can lead to data exfiltration, internal network scanning, or abuse of trusted server permissions. The vulnerability is remotely exploitable without authentication, increasing its severity.
