What is CVE-2026-11346?

A Server-Side Request Forgery (SSRF) vulnerability in the custom process creation feature of linqi allows an authenticated attacker to probe internal network components. By crafting a specific process containing an HTTP Request component, an attacker can force the server to send arbitrary HTTP requests. By observing the varying application responses (Success, Failed, or 504 Gateway Time-out), the attacker can determine the status of internal ports, leading to internal network reconnaissance.
