Reflected XSS via unescaped GET parameters

Published Aug 10, 2023 · Updated Apr 28, 2026

Reflected XSS in Teplitsa of Social Technologies Leyka 3.30.2 and earlier allows remote attackers to inject scripts through crafted URLs. Several GET parameters are reflected into generated pages without sufficient input sanitization or output escaping. Execution requires a user to follow an attacker-crafted link, after which the script runs in the affected site's origin and can read or alter browser-accessible data.
