What is CVE-2026-79678?

A vulnerability exists in FreeIPA's idp-add command where insufficient validation of the --organization and --base-url parameters can lead to critical issues. This flaw allows authenticated users, irrespective of their privilege level, to exploit a constrained eval() call before LDAP access control checks are applied. Consequently, the attacker can enumerate and access sensitive environment variables of the server process, which may result in service disruption due to memory exhaustion, posing a significant risk to the stability and security of the affected systems.
