CloudPirates Open Source Helm Charts is a collection of Helm charts. Prior to commit 271d415, pullrequesttarget workflow is vulnerable to cache poisoning and OIDC token theft. A pullrequesttarget workflow checks out fork code using github.event.pullrequest.head.sha or .head.ref. This gives attacker-controlled code access to base repository secrets and tokens. A pullrequesttarget 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.
