The vulnerability CVE-2025-64383 affects Qode Qi Blocks (versions up to 1.4.3) and is caused by improper neutralization of input during web page generation, leading to stored cross-site scripting (XSS). This allows an attacker with at least low privileges and user interaction to inject malicious scripts that can execute in the context of other users. The CVSS 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-medium.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of affected users, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability. The CVSS score of 6.5 reflects a medium impact level. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — no official fixes or vendor advisories are currently available. Users of Qode Qi Blocks should monitor vendor communications for updates and apply any future patches promptly. Until a fix is available, consider restricting user input or applying web application firewall rules to detect and block potential XSS payloads.
