The MediaView plugin for WordPress (versions up to 1.1.2) contains a reflected XSS vulnerability (CWE-79) via the 'id' parameter due to inadequate input validation and output escaping. This flaw allows unauthenticated attackers to inject malicious scripts that execute when a victim interacts with a crafted link. The vulnerability has a CVSS 3.1 base score of 6.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction needed, scope changed, and low impact on confidentiality and integrity. No patch or official remediation is currently available, and no exploits are known in the wild.

Successful exploitation can lead to execution of arbitrary scripts in the context of the victim's browser session, potentially allowing theft of sensitive information or session hijacking. The impact is limited to confidentiality and integrity with no availability impact. Since the attack requires user interaction and no privileges, the risk is moderate. 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 released, users should consider disabling or removing the MediaView plugin if feasible. Additionally, applying web application firewall (WAF) rules to detect and block suspicious input in the 'id' parameter may reduce risk. Monitor vendor channels for updates and apply patches promptly once available.
