Reflected XSS in Persian WooCommerce SMS Plugin

The افزونه پیامک ووکامرس | Persian WooCommerce SMS WordPress plugin before 7.3.2 does not sanitise and escape a parameter before reflecting it back into an HTML attribute, leading to Reflected Cross-Site Scripting that is executed in the browser session of a logged-in privileged user who is tricked into submitting a crafted cross-site request.

Casky was already ahead

This CVE exploits attack patterns that Casky's 323matched 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

The Persian WooCommerce SMS WordPress plugin versions before 7.3.2 contain a reflected Cross-Site Scripting (XSS) vulnerability stemming from improper input sanitization and output encoding. An attacker can craft a malicious URL containing unescaped parameters that, when clicked by an authenticated administrator or privileged user, executes arbitrary JavaScript in their browser session. This is particularly dangerous for WordPress installations serving Persian-speaking merchants, as it enables attackers to hijack administrator credentials, inject malicious code into the site, modify SMS configurations, or exfiltrate sensitive customer data. The vulnerability requires user interaction but specifically targets privileged users whose compromised sessions have broad site permissions.

Casky's Claude-powered analysis maps this vulnerability to MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance), identifying the attack chain where adversaries probe for unpatched plugin instances and craft phishing campaigns to trigger the XSS. Practitioners using Casky would see 323 matching skills flagging multiple detection vectors: input validation gaps where user-supplied parameters bypass sanitization functions, output encoding failures in HTML attribute contexts, and browser-based execution patterns indicative of stored/reflected XSS. The platform's extended reasoning capability helps security teams distinguish this reflected XSS from stored variants, pinpoint the exact parameter requiring escaping (likely SMS-related fields), and correlate exploitation attempts with authentication logs showing privileged user engagement—enabling rapid response before malicious scripts execute with admin privileges.
