Executive Summary

The vulnerability exists in pygeoapi, a Python server implementation of the OGC API standards. Specifically, in versions from 0.23.0 to before 0.23.3, the OGC API process execution requests can misuse the subscriber object to make requests to internal HTTP services. This could allow unauthorized access or interaction with internal services that should not be exposed.

This issue was fixed in version 0.23.3 of pygeoapi.

Impact Analysis

This vulnerability can have a significant impact because it allows an attacker to make unauthorized requests to internal HTTP services through the subscriber object in the OGC API process execution requests.

According to the CVSS v3.1 score of 8.6 (High severity), the vulnerability can lead to a complete compromise of confidentiality (C:H) without requiring privileges or user interaction.

This means sensitive internal services and data could be exposed or accessed by attackers remotely, potentially leading to data breaches or further exploitation.

Mitigation Strategies

The vulnerability in pygeoapi versions from 0.23.0 to before 0.23.3 has been patched in version 0.23.3.

To mitigate this vulnerability, you should immediately upgrade pygeoapi to version 0.23.3 or later.
