Executive Summary

The vulnerability exists in PraisonAI versions prior to 4.5.90, specifically in the passthrough() and apassthrough() functions. These functions accept a caller-controlled api_base parameter, which is concatenated with an endpoint and passed directly to httpx.Client.request() when a certain error occurs. There is no validation of the URL scheme, no filtering of private IP addresses, and no domain allowlist applied. This means an attacker can make requests to any host reachable from the server, potentially abusing the system to access unauthorized network resources.

Impact Analysis

This vulnerability can allow an attacker with limited privileges to make arbitrary HTTP requests from the server to any reachable host. Because there is no restriction on the destination, it could be used to access internal or private network resources that are normally inaccessible, potentially leading to information disclosure or unauthorized network interactions. The CVSS score of 7.7 indicates a high severity impact on confidentiality.

Compliance Impact

The vulnerability allows an attacker to make arbitrary HTTP requests from the server to any host reachable from it, due to lack of URL scheme validation, private IP filtering, or domain allowlisting.

This could potentially lead to unauthorized data access or data exfiltration, which may impact compliance with standards and regulations such as GDPR or HIPAA that require protection of sensitive data and prevention of unauthorized access.

However, the provided information does not explicitly describe the direct impact on compliance with these standards.
