What is CVE-2026-40114?

PraisonAI, a multi-agent team system, contains a vulnerability in its /api/v1/runs endpoint, which allows the acceptance of an arbitrary webhook URL without proper validation. This flaw enables unauthenticated attackers to exploit the system by submitting jobs that result in the server executing POST requests to potentially malicious external or internal addresses. This not only raises the risk of server-side request forgery (SSRF) but also exposes sensitive cloud metadata, internal APIs, and adjacent network services to unauthorized access. The vulnerability has been addressed in PraisonAI version 4.5.128.
