{"id":"CVE-2026-54532","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-54532","generatedAt":"2026-10-28T02:56:27.895Z","title":"Prior to commit 271d415, pull_request_target workflow is 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.","published":"2026-10-22T18:17:29.000Z","lastModified":"2026-10-23T19:57:43.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:N/I:H/A:L"},"cwe":["CWE-829"],"affected":[],"epss":{"score":0.00187,"percentile":0.08216,"date":"2026-10-26","history":[{"date":"2026-10-23","score":0.00187,"percentile":0.07882}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.19%).
