CVE-2026-79678
Freeipa: idm: freeipa: idp-add eval() reachable before authorization check allows environment disclosure and denial of service
CVSS Score
8.1
EPSS Score
0.9%
EPSS Percentile
59th
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.
