CVE-2026-115221

The ipa-enrollment SLAPI plugin in FreeIPA has a null pointer dereference vulnerability. A remote authenticated client can send a malformed LDAP extended operation, omitting the request value for JOIN_OID, causing a server crash and denial of service.

FreeIPA 4.x with API version 2.213 allows remote authenticated users to bypass intended account-locking restrictions via an unlock action with an old session ID (for the same user account) that had been created for an earlier session.

FreeIPA might display user data improperly via vectors involving non-printable characters.

FreeIPA uses a default password policy that locks an account after 5 unsuccessful authentication attempts. This allows remote attackers to cause a denial of service by locking out the account in which system services run on.

FreeIPA version 4.4.0 allows remote attackers to request an arbitrary SAN name for services.

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.

A flaw was found in FreeIPA. When a trust relationship is configured with Active Directory, AD users can bypass authentication for FreeIPA services by impersonating a client name in the TGS due to missing PAC certificate verification. This could allow an authenticated AD user to escalate privileges within the FreeIPA domain.

A privilege escalation from host to domain vulnerability was found in FreeIPA. The lack of uniqueness validation for the `krbCanonicalName` attribute of the admin account allows creating a service with the same canonical name as the REALM admin. A successful attack lets the attacker obtain a Kerberos ticket with admin@REALM credentials.

In FreeIPA before version 4.2.2, the ipa-kra-install script places the CA agent certificate and private key in /etc/httpd/alias/kra-agent.pem, which is world readable.

A DOM-based Cross-Site Scripting (XSS) vulnerability exists in the FreeIPA/IdM Web UI password reset page. An unauthenticated remote attacker can exploit it by enticing a victim to click a crafted link and complete a password reset, allowing injection and execution of arbitrary JavaScript in the victim's session.
