The WP fancybox WordPress plugin by Noor Alam suffers from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This flaw allows an attacker with low privileges to inject malicious scripts that execute in the context of other users, potentially leading to data disclosure or other impacts. The issue affects all versions up to 1.0.3. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with impacts on confidentiality, integrity, and availability rated as low to low to low respectively.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability. However, exploitation requires the attacker to have low privileges and the victim to interact with malicious content. No known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or fix information is available, users should monitor the vendor's communications for updates. Until a fix is released, consider restricting plugin usage or applying temporary mitigations such as input validation or disabling the plugin if feasible.
