The vulnerability CVE-2025-46542 in ThemeXpert Xpert Tab (<= 1.3) is a stored cross-site scripting (XSS) flaw caused by improper input neutralization during web page generation. This allows an attacker with low privileges and requiring user interaction to inject malicious scripts that persist and execute in the context of other users' browsers, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS 3.1 score of 6.5 reflects network attack vector, low attack complexity, required privileges, and user interaction with scope changed. No patch or official remediation information is currently available.

Successful exploitation can lead to execution of arbitrary scripts in the context of affected users, potentially allowing theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability to a limited degree. The vulnerability requires user interaction and low privileges, limiting the ease of exploitation. No known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
