This flaw stems from inadequate input sanitization of the \u003ccode\u003epost-author\u003c/code\u003e parameter and insufficient preparation within the existing SQL query structure. Specifically, all versions of the plugin up to and including version 4.2.3 are affected. An unauthenticated attacker can exploit this vulnerability by injecting malicious SQL code into the \u003ccode\u003epost-author\u003c/code\u003e parameter. Successful exploitation allows the attacker to manipulate database queries and extract sensitive information without requiring authentication. This vulnerability poses a significant risk to e-commerce sites using the WCAPF plugin, as attackers could potentially access customer data, administrative credentials, or other confidential information.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn unauthenticated attacker identifies a WooCommerce website using a vulnerable version (\u0026lt;=4.2.3) of the WCAPF plugin.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious HTTP request targeting an endpoint that utilizes the vulnerable \u003ccode\u003epost-author\u003c/code\u003e parameter.\u003c/li\u003e\n\u003cli\u003eThe crafted request includes SQL injection payload within the \u003ccode\u003epost-author\u003c/code\u003e parameter, designed to extract data using time-based techniques.

Furthermore, administrative credentials could be stolen, allowing the attacker to gain full control over the website. This can result in significant financial losses, reputational damage, and legal liabilities for the affected e-commerce business. While the exact number of affected websites is unknown, any online store using the WCAPF plugin versions 4.2.3 or earlier is potentially at risk.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUpgrade the WCAPF plugin to a version greater than 4.2.3 to patch CVE-2026-3396 (references: CVE-2026-3396).\u003c/li\u003e\n\u003cli\u003eDeploy the Sigma rule \u003ccode\u003eDetect WooCommerce SQL Injection Attempt\u003c/code\u003e to identify potential exploitation attempts in web server logs (references: Sigma rule).\u003c/li\u003e\n\u003cli\u003eImplement input validation and sanitization on the \u003ccode\u003epost-author\u003c/code\u003e parameter to prevent SQL injection attacks (references: Attack Chain).\u003c/li\u003e\n\u003cli\u003eMonitor web server logs for suspicious requests containing SQL injection payloads, particularly those targeting WCAPF plugin endpoints (references: Sigma rule, Attack Chain).\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-04-08T12:16:21Z","date_published":"2026-04-08T12:16:21Z","id":"/briefs/2026-04-woocommerce-sqli/","summary":"The WCAPF - WooCommerce Ajax Product Filter plugin is vulnerable to time-based SQL Injection (CVE-2026-3396) due to insufficient escaping and SQL query preparation, allowing unauthenticated attackers to extract sensitive information from the database in versions up to 4.2.3.","title":"WooCommerce Ajax Product Filter Plugin Vulnerable to SQL Injection (CVE-2026-3396)","url":"https://feed.craftedsignal.io/briefs/2026-04-woocommerce-sqli/"}],"language":"en","title":"CraftedSignal Threat Feed — Cve-2026-3396","version":"https://jsonfeed.org/version/1.1"}
