WP Directory Kit public tree search permits SQL injection
WP Directory Kit before 1.5.6 passes public search_location or search_category values to wdk_treefield_select_ajax() when a non-default category or location search-field type is configured. Version 1.5.5 collects the selected values and interpolates their comma-joined IDs into SQL IN(...) and FIELD(...) clauses without integer conversion. An unauthenticated attacker can inject SQL and extract database information. Version 1.5.6 casts every selected item to an integer before building the query.

This CVE was published Aug 12, 2026 and is one of 31 known issues for this plugin.
Update, patch or deactivate.
Update to 1.5.6 or later. Review public tree-search requests and database logs for injection probes, and rotate secrets if database information may have been extracted.
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.
Technical description
