CVE-2026-22869 is a critical vulnerability classified under CWE-94 (Improper Control of Generation of Code), affecting the eigent-ai eigent product's continuous integration (CI) workflow. The root cause lies in the GitHub Actions workflow file (.github/workflows/ci.yml), which uses the pull_request_target event trigger. This trigger runs workflows in the context of the base branch, granting elevated permissions, but the workflow also checks out code from untrusted forked pull requests. This combination allows an attacker submitting 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, manipulate the repository by pushing unauthorized code changes, post comments, or even create releases. The vulnerability affects all versions of eigent prior to the commit bf02500bbbab0f01cd0ed8e6dc21fe5683d6bfb5. The CVSS 4.0 score is 8.9 (high severity), reflecting the network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability. Although no exploits have been observed in the wild yet, the vulnerability is considered highly exploitable due to the common use of GitHub Actions and forked pull requests in open source and enterprise development workflows. The vulnerability underscores the risks of misconfigured CI workflows that grant excessive permissions to untrusted code execution contexts.

For European organizations, this vulnerability poses a significant risk to the security of their software development lifecycle and source code integrity. Organizations using eigent in their CI pipelines may face unauthorized disclosure of sensitive credentials, including tokens and keys stored as GitHub secrets, leading to broader compromise of internal systems or cloud environments. Attackers could inject malicious code into the repository, potentially introducing backdoors or supply chain compromises that affect downstream consumers. The ability to create releases or push code unauthorizedly can disrupt software delivery and damage organizational reputation. Given the widespread adoption of GitHub and CI/CD pipelines in European tech sectors, this vulnerability could impact software vendors, financial institutions, government agencies, and critical infrastructure providers relying on eigent for automation. The risk is amplified in collaborative projects with external contributors or public repositories, common in open source and multinational enterprises. Failure to remediate promptly could lead to data breaches, service outages, and regulatory non-compliance under GDPR and other data protection laws.

To mitigate this vulnerability, organizations should immediately review and update their eigent CI workflows to avoid using the pull_request_target trigger when checking out code from untrusted forks. Instead, use the pull_request trigger, which runs workflows with the permissions of the contributor, limiting exposure. Restrict access to repository secrets by configuring GitHub Actions to not expose secrets to workflows triggered by forked pull requests. Implement strict permission boundaries in workflows, such as least privilege principles for tokens and credentials. Consider using GitHub's built-in security features like required reviews and branch protection rules to limit who can merge code. Regularly audit CI/CD configurations for insecure patterns and keep eigent updated to versions beyond bf02500bbbab0f01cd0ed8e6dc21fe5683d6bfb5 once patches are available. Additionally, monitor CI logs for suspicious activity and employ runtime detection for anomalous behavior during builds. Educate developers and DevOps teams on secure CI practices to prevent similar misconfigurations.
