Reflected cross-site scripting (XSS) in Rukovoditel CRM 3.6.4's Zadarma telephony API endpoint allows remote attackers to execute arbitrary JavaScript in victim browsers without authentication. The vulnerability stems from direct reflection of the 'zd_echo' GET parameter without sanitization. With CVSS 9.3 (Critical), changed scope (S:C), and no authentication required (PR:N), this enables session hijacking and account takeover via malicious links. No public exploit identified at time of analysis, though proof-of-concept is trivial given the code-level disclosure. EPSS data not available.
