CVE-2026-79678: Freeipa: idm: freeipa: idp-add eval() reachable before authorization check allows environment disclosure and denial of service

Noroxi assessment

Priority: Monitor (action score 32/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.88% (FIRST EPSS); higher than 58.9% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: ipa-client (AlmaLinux:10) 4.13.4-1.el10_2; ipa-client-common (AlmaLinux:10) 4.13.4-1.el10_2; ipa-client-encrypted-dns (AlmaLinux:10) 4.13.4-1.el10_2.

Low priority for now. Upgrade to ipa-client (AlmaLinux:10) 4.13.4-1.el10_2; ipa-client-common (AlmaLinux:10) 4.13.4-1.el10_2; ipa-client-encrypted-dns (AlmaLinux:10) 4.13.4-1.el10_2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
