Doc Text:
A flaw was found in IntelliJ IDEA. By convincing a user to index a project containing a crafted annotations.xml file, an attacker can trigger Server-Side Request Forgery (SSRF)—a vulnerability where an application is coerced into making unintended network requests. Successful exploitation may allow an attacker to probe internal network resources, leading to unauthorized information disclosure.
