CVE-2026-54532
MediumCVSS 6.9Summary
CloudPirates Open Source Helm Charts is a collection of Helm charts. Prior to commit 271d415, the pull_request_target workflow is vulnerable to cache poisoning and OIDC token theft. It checks out fork code using github.event.pull_request.head.sha or .head.ref, giving attacker-controlled code access to base repository secrets and tokens. A poisoned cache entry written by the workflow can execute during a subsequent release or publish workflow that restores from the same cache scope.
Risk Assessment
This can lead to theft of OIDC tokens and repository secrets and to execution of malicious code during the release process.
Recommendation
Update to commit 271d415 or later and review pull_request_target workflows for safe fork code checkout and cache isolation.

See all- CVE-2026-45132Critical
In CloudPirates Open Source Helm Charts prior to commit fcf9302, a GitHub Actions workflow (generate-schema.yaml) exposes sensitive credentials (Personal Access Token and SSH signing key) to fork-controlled code due to unsafe checkout and credential handling.
- CVE-2026-45131Critical
In CloudPirates Open Source Helm Charts prior to commit fcf9302, a GitHub Actions workflow (pull-request.yaml) executes attacker-controlled code from forks in a privileged context, exposing repository secrets including Docker Hub credentials.
Original NVD description (English source)
CloudPirates Open Source Helm Charts is a collection of Helm charts. Prior to commit 271d415, pull_request_target workflow is vulnerable to cache poisoning and OIDC token theft. A pull_request_target workflow checks out fork code using github.event.pull_request.head.sha or .head.ref. This gives attacker-controlled code access to base repository secrets and tokens. A pull_request_target workflow writes to a shared Actions cache. A subsequent release or publish workflow restores from the same cache scope, allowing a poisoned cache entry to execute during release. This issue has been patched via commit 271d415.
