Kirki family parameter permits arbitrary directory deletion

Kirki 6.0.13 and earlier trusts a caller-controlled family value while handling font data. An authenticated editor can supply a traversal or absolute path and cause directories outside the intended font location to be deleted, creating a direct availability and data-loss risk.

Weakness
CWE-22 — Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

This CVE was published Jul 17, 2026 and is one of 17 known issues for this plugin.

What to do

Update, patch or deactivate.

Update Kirki to a release newer than 6.0.13. Until then, reject traversal, absolute paths, and PHP-style stream wrappers in the family parameter.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
