CVE-2026-22869 is a critical code injection vulnerability categorized under CWE-94 affecting the eigent-ai eigent product. The vulnerability arises from improper control in the continuous integration (CI) workflow defined in the .github/workflows/ci.yml file. Specifically, the workflow uses the GitHub Actions trigger pull_request_target, which runs in the context of the base repository and has elevated permissions, combined with checking out code from untrusted forked pull requests. This misconfiguration allows an attacker who submits a malicious pull request from a fork to execute arbitrary code within the CI environment without requiring authentication or user interaction. The attacker can leverage this to steal sensitive credentials stored as secrets in the repository, push unauthorized code changes, post comments, or create releases, thereby compromising the integrity and confidentiality of the repository and its development lifecycle. The CVSS 4.0 score of 8.9 reflects the high impact and ease of exploitation, with no privileges or user interaction required. Although no exploits are currently known in the wild, the vulnerability poses a significant risk to organizations relying on eigent for their multi-agent workforce automation and CI/CD pipelines. The affected versions are all prior to commit bf02500bbbab0f01cd0ed8e6dc21fe5683d6bfb5, and no official patches or mitigations are linked yet, emphasizing the need for immediate attention to workflow configuration and version updates once available.

For European organizations, this vulnerability threatens the confidentiality, integrity, and availability of software development workflows and codebases. Exploitation could lead to credential theft, enabling further lateral movement or supply chain attacks. Unauthorized code pushes and release creations can introduce backdoors or malicious functionality into production software, undermining trust and compliance with regulations such as GDPR. Organizations using eigent in critical infrastructure or sensitive projects face heightened risks of operational disruption and reputational damage. The vulnerability's ease of exploitation without authentication or user interaction increases the attack surface, especially for projects accepting external contributions via forks. This could also impact open-source projects hosted or maintained by European entities, potentially affecting a broad ecosystem. The lack of known exploits in the wild currently provides a window for proactive mitigation, but the high severity demands urgent remediation to prevent future attacks.

1. Immediately review and modify the CI workflow to avoid using the pull_request_target trigger with untrusted code checkouts. Instead, use pull_request triggers that run in the context of the contributor's permissions. 2. Restrict or disable the use of repository secrets in workflows triggered by pull requests from forks. 3. Implement strict branch protection rules and require manual review before merging pull requests from external contributors. 4. Monitor CI logs and repository activity for suspicious behavior indicative of exploitation attempts. 5. Update eigent to the fixed version once available or apply vendor-provided patches promptly. 6. Educate development teams about secure CI/CD practices, especially regarding GitHub Actions triggers and permissions. 7. Consider isolating CI environments and limiting permissions granted to workflows to minimize potential damage from code injection. 8. Use tools to scan workflow configurations for insecure patterns automatically. These steps go beyond generic advice by focusing on the specific misuse of pull_request_target and untrusted code checkout in GitHub Actions workflows.
