CVE-2026-76578: Ipa: freeipa: freeipa: unauthenticated ldap client can obtain administrator credentials via the self-managed-token aci

Noroxi assessment

Priority: Monitor (action score 39/100)

Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 1.2% (FIRST EPSS); higher than 68.1% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
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. The self-managed OTP token ACI does not require authentication and does not restrict which attributes may be added alongside the token entry. An unauthenticated LDAP client can exploit this, combined with a related flaw in the underlying directory server's ACI evaluation (tracked separately), to create an arbitrary attacker-controlled Kerberos principal and have it added to the administrators group. This allows a remote, unauthenticated attacker to obtain genuine FreeIPA administrator-group membership and perform administrative operations against the directory and, on SID-enabled deployments, other IdM services.
