There is no fixed version for RHEL:10 sssd.

NVD Description

Note: Versions mentioned in the description apply only to the upstream sssd package and not the sssd package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

It was found that sssd's sysdb_search_user_by_upn_res() function before 1.16.0 did not sanitize requests when querying its local cache and was vulnerable to injection. In a centralized login environment, if a password hash was locally cached for a given user, an authenticated attacker could use this flaw to retrieve it.
