Detailsinfo

A vulnerability was found in MervinPraison PraisonAI up to 4.5.139. It has been declared as critical. This vulnerability affects an unknown function. The manipulation of the argument GITHUB_TOKEN with an unknown input leads to a inclusion of functionality from untrusted control sphere vulnerability. The CWE definition for the vulnerability is CWE-829. The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

PraisonAI is a multi-agent teams system. In versions 4.5.139 and below, the GitHub Actions workflows are vulnerable to ArtiPACKED attack, a known credential leakage vector caused by using actions/checkout without setting persist-credentials: false. By default, actions/checkout writes the GITHUB_TOKEN (and sometimes ACTIONS_RUNTIME_TOKEN) into the .git/config file for persistence, and if any subsequent workflow step uploads artifacts (build outputs, logs, test results, etc.), these tokens can be inadvertently included. Since PraisonAI is a public repository, any user with read access can download these artifacts and extract the leaked tokens, potentially enabling an attacker to push malicious code, poison releases and PyPI/Docker packages, steal repository secrets, and execute a full supply chain compromise affecting all downstream users. The issue spans numerous workflow and action files across .github/workflows/ and .github/actions/. This issue has been fixed in version 4.5.140.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-40313 since 04/10/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are known technical details, but no exploit is available.

Upgrading to version 4.5.140 eliminates this vulnerability.
