The Kirki WordPress plugin before 6.0.13 does not properly sanitise and escape a value taken from the request before using it in a SQL statement, allowing unauthenticated attackers to perform SQL injection attacks.
Articles & Coverage 1
AnalysisAI
SQL injection in the Kirki WordPress plugin before version 6.0.13 enables unauthenticated remote attackers to read arbitrary data from the underlying WordPress database by injecting malicious SQL through an unsanitized request parameter. The CVSS vector scores this 8.6 with a scope change reflecting potential access to the database tier beyond the web application boundary, with high confidentiality impact but no integrity or availability impact - consistent with a read-only injection primitive. A public proof-of-concept exploit exists per WPScan, though the EPSS score of 0.18% (7th percentile) indicates low observed exploitation probability relative to the theoretical severity, and the vulnerability has not been added to the CISA KEV catalog.
Technical ContextAI
Kirki is a WordPress plugin that extends the WordPress Theme Customizer API, providing a framework for theme developers to build rich customization interfaces. The affected code path accepts a value directly from the HTTP request and interpolates it into a SQL statement without sanitization or parameterization, a textbook CWE-89 (Improper Neutralization of Special Elements used in a SQL Command) defect. WordPress plugins interact with the WordPress-managed MySQL database via the wpdb class, which provides prepared statement helpers; the failure to use these helpers or equivalent escaping functions is the root cause. The CPE string cpe:2.3:a:unknown:kirki:*:*:*:*:*:*:*:* covers all versions of Kirki up to (exclusive) 6.0.13, as confirmed by EUVD entry EUVD-2026-51432.
RemediationAI
Update the Kirki WordPress plugin to version 6.0.13 or later, which contains the vendor-released fix for this SQL injection. The WPScan advisory at https://wpscan.com/vulnerability/4cba3900-9f29-4928-811c-163827358052/ provides further detail. If immediate patching is not feasible, a compensating control is to deactivate the Kirki plugin entirely until the update can be applied - this eliminates the attack surface at the cost of disabling theme customization functionality. An alternative short-term measure is to deploy a web application firewall (WAF) rule blocking SQL metacharacter patterns in requests to WordPress endpoints, though WAF rules can be bypassed by encoding or obfuscation and should not substitute for patching. No other mitigations specific to this parameter are identifiable from the available data.
