DescriptionCVE.org

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in FunnelKit Funnel Builder by FunnelKit allows Blind SQL Injection.

This issue affects Funnel Builder by FunnelKit: from n/a through 3.15.0.5.

AnalysisAI

Blind SQL injection in FunnelKit Funnel Builder for WordPress (versions up to and including 3.15.0.5) allows authenticated attackers with high privileges to inject arbitrary SQL queries against the underlying database. The flaw is reported by Patchstack and tracked as CWE-89; no public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV. The CVSS scope change combined with confidentiality impact indicates database contents beyond the plugin context can be exfiltrated one bit at a time via blind techniques.

Technical ContextAI

FunnelKit Funnel Builder (formerly WooFunnels) is a WordPress plugin used to build sales funnels, checkout flows, and order bumps on top of WooCommerce. The CWE-89 root cause is Improper Neutralization of Special Elements in an SQL Command: user-controlled input is concatenated into a SQL statement without parameterized queries or proper escaping via wpdb->prepare(). Because the resulting query runs against the shared WordPress database (wp_users, wp_options, wp_usermeta), a successful injection can read data far outside the plugin's own tables. The CPE cpe:2.3:a:funnelkit:funnel_builder_by_funnelkit covers all builds from initial release through 3.15.0.5.

RemediationAI

Upstream fix available (PR/commit); released patched version not independently confirmed from the supplied data - operators should upgrade FunnelKit Funnel Builder to the first release above 3.15.0.5 as soon as the vendor publishes it and consult the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/funnel-builder/vulnerability/wordpress-funnel-builder-by-funnelkit-plugin-3-15-0-5-sql-injection-vulnerability for the exact fixed build. Until a patched version is installed, restrict who holds Administrator and Shop Manager roles, audit existing privileged accounts, and enforce strong MFA on wp-admin to reduce the chance that the high-privilege precondition is met. A WordPress WAF (Wordfence, Patchstack mu-plugin, or equivalent) with a virtual patch for this CVE can block the malicious payloads at the request layer, at the cost of false positives on legitimate admin queries; database-layer monitoring for UNION/SLEEP/BENCHMARK patterns in plugin queries provides defense-in-depth detection.
