CVE-2026-79678

Freeipa: idm: freeipa: idp-add eval() reachable before authorization check allows environment disclosure and denial of service

Published Sep 7, 2026 CVSS 3.1 · 8.1 High EPSS < 1% KEV · Not listed
Description
A flaw was found in FreeIPA's idp-add command, where insufficiently validated --organization/--base-url input reaches a constrained eval() call before the corresponding LDAP access control check is enforced. This allows any authenticated IPA principal, regardless of privilege level, to enumerate and read the environment variables of the affected server process and to cause denial of service via memory exhaustion.

Remediation

Vendor Workaround

There is no configuration-based mitigation that prevents an authenticated but unprivileged principal from reaching the affected code path; upgrading to a fixed package is required once available. Administrators of container-based deployments should verify that credentials supplied via the PASSWORD environment variable during initial container setup do not persist in the running server process's environment.
