Overview
The CVE-2025-52467 is a critical cybersecurity vulnerability affecting the pgai Python library. Specifically, this vulnerability exposes all secrets used in one workflow, including the GITHUB_TOKEN with write permissions for the repository. This vulnerability exposes all users of the pgai Python library to potential system compromise or data leakage. In the wrong hands, this vulnerability could provide attackers with full access to tamper with the repository, which could include pushing arbitrary code and releases.

How the Exploit Works
The vulnerability lies in the pgai Python library’s handling of secrets. The library, which transforms PostgreSQL into a retrieval engine for RAG and Agentic applications, does not adequately secure secrets used in workflows. This issue means that an attacker can exploit the vulnerability to exfiltrate all secrets in a workflow, including the GITHUB_TOKEN. The GITHUB_TOKEN has write permissions for the repository, so an attacker could use this token to manipulate the repository, including adding arbitrary code and releases.
Conceptual Example Code
The below example demonstrates how an attacker might exploit the vulnerability. It illustrates a malicious HTTP POST request that could exfiltrate the secrets used in a workflow:
POST /exfiltrate-secrets HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "name": "GITHUB_TOKEN" }In this example, the attacker makes a POST request to the /exfiltrate-secrets endpoint, requesting the GITHUB_TOKEN. If the vulnerability exists, the system would return the token in the response, giving the attacker unauthorized access to the repository.
Mitigation Guidance
Users of the pgai Python library should immediately update their software to the latest version that includes the patch for this vulnerability (commit 8eb3567 or later). If an immediate update is not possible, it is recommended to use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure. These systems can help detect and block attempts to exploit the vulnerability.
