This vulnerability (CVE-2026-54195) affects Jetmonsters JetFormBuilder versions up to and including 3.6.0.1. It is an unauthenticated cross-site scripting (XSS) issue caused by improper neutralization of input during web page generation (CWE-79). The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability. No vendor advisory or patch information is currently available, and no known exploits have been reported.

Successful exploitation allows an unauthenticated attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to user session hijacking, defacement, or redirection to malicious sites. The vulnerability impacts confidentiality, integrity, and availability at a low level but can facilitate further attacks due to the cross-site scripting nature.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider applying temporary mitigations such as input validation and output encoding on affected inputs if possible. Monitor vendor communications for updates and apply patches promptly once available.
