Praisonai · Praisonai · CVE-2026-55535
**Name of the Vulnerable Software and Affected Versions**
PraisonAI versions prior to 4.6.58
**Description**
The Jobs API contains a flaw where the `validate webhook url()` function fails open when a `socket.gaierror` occurs during DNS resolution. This allows the `webhook url` parameter to bypass validation if the domain is unresolvable or via a DNS rebinding attack, where a domain initially resolves to a public IP to pass validation and subsequently resolves to an internal address. This can lead to Server-Side Request Forgery (SSRF), enabling an unauthenticated attacker to make requests to internal HTTP services, such as admin panels, databases, or cloud metadata APIs like `http://169.254.169.254/`.
**Recommendations**
Update PraisonAI to version 4.6.58.
As a temporary mitigation, restrict or avoid using the `webhook url` parameter in the Jobs API until the update is applied.
