CVE-2026-50562Network attack vector

Supply-chain compromise via unverified PR artifacts

Published Jul 15, 2026 · Updated Jul 15, 2026

CI/CD trust failure in FastGPT at commit 22ebfacbb43311e9b73294040ae0eb87390c6bba and earlier allows remote attackers to push untrusted images. The low-privilege build jobs accept PR-controlled Docker contexts, while privileged workflow_run jobs download the resulting artifacts without trusted-origin or provenance checks. A fork pull request reaching these workflows is sufficient to push an attacker-controlled image to GHCR and, in the documentation path, deploy it with Kubernetes credentials.
