CVE-2026-14476

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.

What this means for your business

  • An attacker can use it remotely, over a network, with an administrator login, and without anyone at your company clicking anything.
  • FIRST's prediction model gives it a 0.7% chance of attack attempts being seen in the next 30 days, ranking above 49% of all known flaws.

What to do

  1. 1Ask your IT team or provider whether any of your systems use the affected product.
  2. 2If you do, follow the vendor's guidance. No patch reference has been published yet.
