This vulnerability in WofficeIO Woffice (<= 5.4.30) involves improper neutralization of input during web page generation, resulting in a reflected Cross-site Scripting (XSS) flaw. The CVSS 3.1 base score is 7.1 (High), with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L, indicating network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability. The vulnerability allows an attacker to inject malicious scripts that execute in the victim's browser session, potentially leading to session hijacking or other script-based attacks. No patch or official fix information is currently available.

Successful exploitation can lead to execution of arbitrary scripts in the context of the victim's browser, potentially compromising user session data and causing limited confidentiality, integrity, and availability impacts. The reflected XSS requires user interaction and can affect all users accessing vulnerable versions of Woffice. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider applying web application firewall (WAF) rules to detect and block reflected XSS attempts and educate users to avoid clicking suspicious links. Monitor vendor channels for updates and apply patches promptly once available.
