The custom\nCredential Type environment-variable injector validates variable names against a\ndeny-list (an ANSIBLE_* prefix check plus a fixed ENV_BLOCKLIST) that omits\nprocess-hijacking loader variables such as BASH_ENV, ENV, LD_PRELOAD, LD_LIBRARY_PATH,\nPYTHONSTARTUP and GIT_SSH_COMMAND. Combined with the credential file injector, a\nprivileged user can write an attacker-controlled script into the execution environment\nand point BASH_ENV at it, obtaining arbitrary code execution inside the\nexecution-environment container for any job that attaches a credential of that type.","published":"2026-09-23T20:17:18.000Z","lastModified":"2026-09-26T23:16:38.000Z","status":"Awaiting Analysis","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":7.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:H/A:N"},"cwe":["CWE-184"],"affected":[],"epss":{"score":0.00306,"percentile":0.23218,"date":"2026-10-26","history":[{"date":"2026-09-24","score":0.00306,"percentile":0.20801}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.31%).
