Authenticated directory deletion via family path traversal
Published Jul 17, 2026 · Updated Jul 17, 2026
Path traversal in Themeum Kirki 6.0.13 and earlier allows remote authenticated users to delete arbitrary server directories. The font-deletion path uses the family parameter to select a filesystem directory without constraining traversal outside the intended font-storage path. Editor-level access or higher is required, and successful exploitation removes directories accessible to the web-server process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
