Summary

CVE-2026-22869 is a critical-severity Code Injection (CWE-94) vulnerability in Eigent Eigent. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Compromise Software Dependencies and Development Tools (T1195.001); ranked at the 41.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 CM-3 (Configuration Change Control) and CM-5 (Access Restrictions for Change).

Threat & Defense at a Glance

What attackers do: exploitation maps to Compromise Software Dependencies and Development Tools (T1195.001) and 2 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

CM-6 Configuration Settings good match

prevent

Establishes and enforces secure configuration settings for CI/CD workflows to prevent use of pull_request_target triggers with untrusted code checkouts from forks.

CM-5 Access Restrictions for Change good match

prevent

Restricts access to CI workflow configuration mechanisms to authorized personnel, preventing malicious modifications that enable arbitrary code execution.

CM-3 Configuration Change Control good match

prevent

Implements configuration change control processes to review and approve modifications to CI workflows, blocking introduction of vulnerable trigger and checkout combinations.

NVD Description

Eigent is a multi-agent Workforce. A critical security vulnerability in the CI workflow (.github/workflows/ci.yml) allows arbitrary code execution from fork pull requests with repository write permissions. The vulnerable workflow uses pull_request_target trigger combined with checkout of untrusted PR code. An…

Deeper analysisAI

CVE-2026-22869, published on 2026-01-13, is a critical vulnerability (CVSS 9.8, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) classified under CWE-94 (Code Injection) affecting Eigent, a multi-agent Workforce project hosted at github.com/eigent-ai/eigent. The flaw resides in the CI workflow defined in .github/workflows/ci.yml, which improperly uses the pull_request_target trigger alongside checkout of untrusted code from pull requests originating from forks. This configuration enables arbitrary code execution within the workflow environment.

Attackers can exploit this vulnerability by submitting a malicious pull request from a forked repository, requiring no special privileges per the CVSS base score (PR:N). Upon triggering the workflow, the untrusted PR code executes with repository write permissions in the base repository's context, allowing attackers to steal secrets or credentials, post comments, push arbitrary code, or create releases.

Mitigation details are outlined in the GitHub security advisory GHSA-gvh4-93cq-5xxp, with fixes applied via commit bf02500bbbab0f01cd0ed8e6dc21fe5683d6bfb5 and pull requests #836 and #837. Security practitioners should audit and update CI workflows to avoid pull_request_target with untrusted checkouts, applying these patches to remediate affected instances.
