SQL Injection in YITH WooCommerce Product Add-Ons

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in YITH YITH WooCommerce Product Add-Ons allows Blind SQL Injection. This issue affects YITH WooCommerce Product Add-Ons: from n/a through 4.29.0.

Casky was already ahead

This CVE exploits attack patterns that Casky's 301matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

This vulnerability is a blind SQL injection flaw in the YITH WooCommerce Product Add-Ons plugin, affecting versions through 4.29.0. Blind SQL injection allows attackers to extract sensitive database information without seeing direct query results, instead inferring data through response timing or boolean-based techniques. This is particularly dangerous for WooCommerce sites because attackers can access customer data, payment information, and product details stored in the database. Any site running the vulnerable plugin versions is at risk, especially if the plugin processes user input in product customization fields without proper parameterization or input validation.

Casky's 301 mapped skills help practitioners detect this vulnerability by identifying the underlying attack patterns tied to MITRE techniques TA0001 (Initial Access) and TA0043 (Reconnaissance). Claude AI's extended reasoning capabilities enable detection of suspicious SQL query patterns, unusual database timing responses, and characteristic blind SQL injection probes in network traffic and application logs. Practitioners using Casky would observe findings related to abnormal database query structures, unexpected input parameter handling in product add-on requests, and potential exploitation attempts that deviate from normal WooCommerce query behavior. The platform's skill mapping to CWE-89 (Improper Neutralization of Special Elements) helps security teams correlate these detection patterns across their environment and prioritize remediation of input validation failures in custom plugin code.
