{"id":"CVE-2026-54532","state":"PUBLISHED","title":"CloudPirates Open Source Helm Charts: pull_request_target workflow vulnerable to cache poisoning and OIDC token theft","description":"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.","publishedAt":"2026-10-22T17:16:38.540Z","updatedAt":"2026-10-22T17:16:38.540Z","severity":{"score":6.9,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:N/I:H/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["CloudPirates-io helm-charts"],"affected":[{"vendor":"CloudPirates-io","product":"helm-charts","versions":[{"version":"< 271d415975a64b7958d2740526dca870b70c8c21","status":"affected"}]}],"references":["https://github.com/CloudPirates-io/helm-charts/security/advisories/GHSA-gv8x-4mc5-r65r","https://github.com/CloudPirates-io/helm-charts/commit/271d415975a64b7958d2740526dca870b70c8c21"],"weaknesses":["CWE-829"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/54xxx/CVE-2026-54532.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-54532","state":"PUBLISHED","datePublished":"2026-10-22T17:16:38.540Z","dateUpdated":"2026-10-22T17:16:38.540Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-15T18:40:01.651Z"},"containers":{"cna":{"title":"CloudPirates Open Source Helm Charts: pull_request_target workflow vulnerable to cache poisoning and OIDC token theft","descriptions":[{"lang":"en","value":"CloudPirates Open Source Helm Charts is a collection of Helm charts.
