Hi,

The following vulnerabilities were published for sssd.

CVE-2026-14474[0]:
| A flaw was found in SSSD's LDAP sudo provider. When the
| ldap_sudo_search_base option is not explicitly configured, SSSD
| searches the entire LDAP directory tree for sudoRole objects. An
| authenticated attacker with write access to any subtree can inject a
| sudoRole object granting root-level sudo privileges on all SSSD-
| enrolled hosts.


CVE-2026-14476[1]:
| A path traversal flaw was found in SSSD's AD GPO provider. The
| ad_gpo_extract_smb_components() function does not sanitize ..
| sequences in the gPCFileSysPath LDAP attribute, allowing an attacker
| with AD GPO management access to write files outside the GPO cache
| directory as root. On default RHEL configurations with SELinux
| enforcing, this can be used to inject Kerberos configuration leading
| to authentication bypass.


If you fix the vulnerabilities please also make sure to include the
CVE (Common Vulnerabilities & Exposures) ids in your changelog entry.
