CVE-2025-32958 is a medium-severity vulnerability affecting the Adept programming language project, specifically versions prior to commit a1a41b7. The vulnerability arises from a misconfiguration in the remoteBuild.yml GitHub Actions workflow file, where the action actions/upload-artifact@v4 is used to upload a mac-standalone artifact. This artifact is a zip archive of the current directory, which inadvertently includes the automatically generated .git/config file. This configuration file contains the GITHUB_TOKEN used by the workflow for authentication with the GitHub API. Because the artifact is accessible for download before the workflow completes, there is a brief window of opportunity—lasting a few seconds—during which an attacker with access to the artifact can extract the GITHUB_TOKEN. With this token, the attacker can interact with the GitHub API with the permissions granted to the token, potentially pushing malicious code, rewriting release commits, or otherwise tampering with the AdeptLanguage/Adept repository. This exposure constitutes a CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) vulnerability. The issue was patched in commit a1a41b7 by presumably removing the sensitive .git/config file from the artifact or changing the workflow to prevent token leakage. No known exploits have been reported in the wild as of the publication date, but the vulnerability poses a risk to the integrity of the source code repository and the trustworthiness of released software artifacts. The vulnerability requires no user interaction but does require an attacker to have access to the artifact download location during the vulnerable window, which may be publicly accessible or restricted depending on repository settings.

For European organizations using or contributing to the Adept programming language or relying on its software artifacts, this vulnerability could lead to unauthorized code injection or tampering within the Adept repository. This compromises the integrity of the software supply chain, potentially allowing malicious code to be introduced into builds or releases. Such tampering can propagate downstream to organizations that depend on Adept, leading to widespread impact. Additionally, unauthorized use of the GITHUB_TOKEN could allow attackers to manipulate release commits, undermining trust in the software's authenticity. The exposure of sensitive tokens also risks further lateral attacks if the token permissions are broad. Given the increasing reliance on open-source software in European industries, especially in sectors like finance, manufacturing, and critical infrastructure, the integrity of development workflows is paramount. This vulnerability could also erode confidence in open-source projects and their security practices. However, the impact is somewhat limited by the short time window for exploitation and the need for access to the artifact download location. Organizations hosting or mirroring the Adept repository or integrating its artifacts into their CI/CD pipelines are at higher risk.

1. Immediate upgrade to the patched version of Adept that includes commit a1a41b7 to ensure the workflow no longer exposes the GITHUB_TOKEN. 2. Review and audit all GitHub Actions workflows to ensure that no sensitive files (such as .git/config) or secrets are included in uploaded artifacts or logs. 3. Restrict artifact download permissions to trusted users only, minimizing the risk of unauthorized access during workflow execution. 4. Rotate any potentially exposed GITHUB_TOKENs or other secrets immediately to invalidate compromised tokens. 5. Implement least privilege principles for GitHub tokens used in workflows, limiting their scope and permissions to only what is strictly necessary. 6. Monitor GitHub repository activity for unusual commits, pushes, or release modifications that could indicate exploitation. 7. Employ automated scanning tools to detect secret leaks in repositories and CI/CD pipelines. 8. Educate development teams on secure CI/CD practices, including careful handling of artifacts and secrets. 9. Consider using ephemeral or short-lived tokens with automatic expiration to reduce the risk window. 10. For organizations relying on Adept artifacts, verify the integrity and provenance of downloaded artifacts before use.
