Detailsinfo

A vulnerability, which was classified as problematic, was found in Okta Access Gateway up to 2026.9.0. Affected is some unknown processing of the component Kerberos configuration handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The Okta Access Gateway Kerberos configuration handler does not validate file paths specified in event payloads before writing file contents. The path from the event payload is used directly as the write destination, resulting in files being written to unintended locations on the appliance filesystem.

The advisory is shared for download at trust.okta.com. This vulnerability is traded as CVE-2026-78620 since 08/24/2026. The exploitability is told to be easy.
