In versions 4.14.8.3 and below, the fastgpt-preview-image.yml workflow is vulnerable to arbitrary code execution and secret exfiltration by any external contributor. The workflow uses pull_request_target, which runs with repository secrets, but checks out code from the pull request author's fork and builds Docker images with attacker-controlled Dockerfiles.

EPSS score is not available, but the lack of a KEV listing does not reduce the potential impact. The likely attack vector is any public pull request authored by an external contributor, which is inferred from the use of pull_request_target. An attacker could exfiltrate secrets, create malicious Docker images, and distribute compromised containers through the registry, resulting in full system compromise. The exploit requires modifying or pushing a PR to the repository; therefore, the vulnerability is exploitable by external PR authors."}}}}, "created": "2026-03-20T10:05:02.966613+00:00", "updated": "2026-03-20T10:26:09.066540+00:00", "vendors": ["labring", "labring$PRODUCT$fastgpt"]}
