Short explanation

Prior to commit 271d415, CloudPirates-io helm-charts features a pull_request_target workflow vulnerable to cache poisoning and OIDC token theft [S0]. This vulnerability allows attacker-controlled code to access base repository secrets and tokens [S1].

Why does it matter?

This security flaw can lead to unauthorized code execution and the exposure of sensitive secrets via a shared Actions cache [S0]. A poisoned cache entry may execute during a subsequent release workflow [S1].

What should be done?

Updating to commit 271d415 [S0]
Following vendor advisories [S0]
Reviewing workflow configurations [S1]

Show the technical text from the sources

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.
