SSRF Vulnerability in PraisonAI /api/v1/runs Endpoint

Publication date: 2026-04-09

Last updated on: 2026-04-17

Assigner: GitHub, Inc.

Description

PraisonAI is a multi-agent teams system. Prior to 4.5.128, the /api/v1/runs endpoint accepts an arbitrary webhook_url in the request body with no URL validation. When a submitted job completes (success or failure), the server makes an HTTP POST request to this URL using httpx.AsyncClient. An unauthenticated attacker can use this to make the server send POST requests to arbitrary internal or external destinations, enabling SSRF against cloud metadata services, internal APIs, and other network-adjacent services. This vulnerability is fixed in 4.5.128.

Attack-Flow Graph

Mitigation Strategies

The vulnerability is fixed in PraisonAI version 4.5.128. The immediate step to mitigate this vulnerability is to upgrade PraisonAI to version 4.5.128 or later.

Compliance Impact

The vulnerability allows an unauthenticated attacker to cause the server to send HTTP POST requests to arbitrary internal or external URLs, potentially enabling Server-Side Request Forgery (SSRF) attacks against sensitive internal services.

Such SSRF vulnerabilities can lead to unauthorized access or exposure of sensitive data, which may impact compliance with standards and regulations like GDPR or HIPAA that require protection of personal and sensitive information.

However, the provided information does not explicitly describe the direct impact on compliance or specific regulatory requirements.

Executive Summary

PraisonAI versions prior to 4.5.128 have a vulnerability in the /api/v1/runs endpoint where it accepts an arbitrary webhook_url in the request body without validating the URL.

When a job submitted to this endpoint completes, the server sends an HTTP POST request to the provided webhook_url using httpx.AsyncClient.

Because there is no URL validation and no authentication required, an attacker can supply a malicious URL to make the server send POST requests to arbitrary internal or external destinations.

This enables Server-Side Request Forgery (SSRF) attacks against cloud metadata services, internal APIs, and other network-adjacent services.

The vulnerability is fixed in version 4.5.128.

Impact Analysis

This vulnerability allows an unauthenticated attacker to make the PraisonAI server send HTTP POST requests to arbitrary internal or external URLs.

Such Server-Side Request Forgery (SSRF) attacks can be used to access sensitive internal services that are not normally exposed externally, such as cloud metadata services or internal APIs.

This can lead to unauthorized access to sensitive information, potential data leakage, or further exploitation of internal network resources.

The vulnerability has a CVSS v3.1 base score of 7.2, indicating a high severity impact on confidentiality and integrity.
