CVE-2026-19550 Freeipa: ipa: freeipa: trust-fetch-domains uses trust-read aci to gate a privileged ad trust refresh, allowing unauthorized ldap writes

Description

A flaw was found in FreeIPA. The trust-fetch-domains command is gated by a read-only permission on the trust object rather than a trust-administration permission, allowing an authenticated, non-privileged IPA user to trigger a privileged Active Directory trust refresh using an attacker-supplied server and credentials, resulting in unauthorized, attacker-controlled modification of trusted-domain and ID-range identity data in the IPA LDAP directory.
