AI-suggested
A fix is available and included in the Red Hat Enterprise Linux 9.8 update. Administrators should apply the update to remediate this vulnerability. Until the fix is applied, restricting the "System: Read Trust Information" permission can serve as an interim workaround, though this may impact SSSD subdomain support. No other mitigation steps are recommended by the vendor.
Description
CVE-2026-19550 is a medium-severity authorization vulnerability in FreeIPA on Red Hat Enterprise Linux 9. It allows an authenticated, non-privileged user to trigger a privileged Active Directory trust refresh using attacker-supplied server and credentials. This can lead to unauthorized modification of trusted-domain and ID-range identity data in the IPA LDAP directory. The vulnerability affects only IdM/FreeIPA servers with established cross-forest trusts with Active Directory. A fix is available upstream and included in Red Hat Enterprise Linux 9.8 updates.
