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.

Update, patch or deactivate.

This archive could not verify a fixed version from the official author release notes reviewed on 2026-10-13. Disable the affected feature or component where practical until remediation for the deployed configuration is established. Until then, reject traversal, absolute paths, and PHP-style stream wrappers in the family parameter. Official author release notes: https://wordpress.org/plugins/kirki/.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

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.
