The DyadyaLesha DL Leadback product suffers from a reflected cross-site scripting vulnerability due to improper input neutralization during web page generation. This vulnerability affects versions up to 1.2.1 and allows attackers to inject malicious scripts that execute when a user interacts with a crafted link or input, potentially compromising user data or session integrity. The CVSS v3.1 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this reflected XSS vulnerability could allow attackers to execute arbitrary scripts in the context of the victim's browser, potentially leading to theft of sensitive information, session hijacking, or disruption of service. The CVSS score reflects limited but meaningful impacts on confidentiality, integrity, and availability. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should apply standard XSS mitigations such as input validation and output encoding where possible.
