2DescriptionCVE.org
The ElementsKit Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 's' parameter of the Advanced Search REST endpoint in all versions up to, and including, 4.10.1 due to insufficient input sanitization and output escaping. The REST endpoint at /wp-json/elementskit/v1/advanced-search uses permission_callback set to __return_true, allowing unauthenticated access. Search terms are stored in the ekit_advanced_search_popular_keyword WordPress option via update_option(). While sanitize_text_field() is applied, it does not encode double quotes, and the stored keywords are rendered in HTML attributes via sprintf without esc_attr(), allowing attribute injection. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user triggers the "no results" popular keywords view on pages using the Advanced Search widget.
AnalysisAI
Stored Cross-Site Scripting in ElementsKit Pro for WordPress allows unauthenticated attackers to persistently inject arbitrary JavaScript via the Advanced Search REST endpoint, affecting all versions through 4.10.1. The flaw combines an authentication bypass (permission_callback set to __return_true) with inadequate output escaping: sanitize_text_field() permits double-quote characters to pass through, and stored keywords are later rendered into HTML attributes using sprintf() without esc_attr(), enabling attribute injection. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The target site must have ElementsKit Pro version 4.10.1 or earlier installed and activated, and the Advanced Search widget must be placed on at least one publicly accessible page. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 6.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) is technically accurate but understates operational risk in several ways. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update ElementsKit Pro to a version beyond 4.10.1 once WPMet releases a patched build; no specific fixed version number has been confirmed in the available references - monitor the plugin changelog and roadmap at https://wpmet.com/plugin/elementskit/roadmaps/ for release announcements. … Detailed patch versions, workarounds, and compensating controls in full report. |
