CVE-2026-45131Network attack vector

Secret exfiltration via ungated fork workflow execution

Published Jun 1, 2026 · Updated Jun 1, 2026

Code injection in CloudPirates Open Source Helm Charts before commit fcf9302 allows remote attackers to steal secrets via fork pull requests. The pull-request.yaml integration-test job uses pull_request_target, checks out fork-controlled code, authenticates with repository secrets, and runs test-charts.sh from that checkout. A fork pull request triggers the job without maintainer approval, enabling arbitrary CI code execution, credential theft, repository writes, and malicious image publication.
