{"id":"CVE-2026-84714","published":"2026-09-23T20:17:18.083","lastModified":"2026-09-24T15:17:44.810","description":"A flaw was found in the automation-controller input-validation\n                  guard sanitize_jinja(). The function uses two regular\n                  expressions to reject user-supplied Jinja, but the patterns\n                  stop at the first interior '}' or '%' character, so a Jinja\n                  expression containing an inner brace (for example an empty\n                  dict) is accepted while remaining valid Jinja. Because\n                  sanitize_jinja() is the sole guard on several launch-time\n                  fields — ad-hoc command module_args, Machine-credential\n                  username / become_method / become_user, and inventory host\n                  names — a low-privileged user can inject Jinja that ansible-core\n                  evaluates in the execution environment. This enables execution\n                  of arbitrary commands in the execution environment (bypassing an\n                  administrator's AD_HOC_COMMANDS module allowlist) and disclosure\n                  of secrets belonging to credentials the attacker cannot read\n                  (by templating a co-attached credential's injected environment\n                  variables), across the credential access-control boundary.","cvssScore":7.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","cwes":["CWE-184"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:71113","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2026:71114","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2026:71177","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2026:71179","tags":[]},{"url":"https://access.redhat.com/security/cve/CVE-2026-84714","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2527198","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
