CVE-2026-62100: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in kutethemes KuteShop

This vulnerability, identified as CWE-79, affects KuteShop versions <= 4.2.9 and involves improper neutralization of input during web page generation, leading to unauthenticated cross-site scripting (XSS). The CVSS 3.1 base score is 7.1, reflecting a network attack vector with low attack complexity, no privileges required, but requiring user interaction. The vulnerability has a scope change and impacts confidentiality, integrity, and availability at a low level. No patch or remediation information is provided in the available data.

Successful exploitation of this vulnerability can allow an unauthenticated attacker to execute arbitrary scripts in the victim's browser when they visit the affected web pages. This can lead to disclosure of sensitive information, modification of web content, and potential disruption of service. The CVSS score indicates a significant risk but does not confirm active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider applying input validation and output encoding controls as temporary mitigations to reduce the risk of XSS. Monitor vendor channels for updates and patches.
