The cornershop Better Section Navigation Widget suffers from a stored XSS vulnerability due to improper input neutralization during web page generation. This allows attackers with at least low privileges and requiring user interaction to inject malicious scripts that can affect confidentiality, integrity, and availability to a limited extent. The vulnerability affects all versions up to 1.6.1. No official patch or fix has been documented in the provided data.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to limited disclosure of information, modification of data, or disruption of service. The CVSS vector indicates network attack vector, low attack complexity, privileges required, user interaction needed, and a scope change, with low impact on confidentiality and integrity and low impact on availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with input handling and consider temporary mitigations such as input validation or output encoding if feasible. Monitor vendor communications for updates on patches or official mitigations.
