This vulnerability involves improper neutralization of input during web page generation in Studio Hyperset's The Great Firewords of China (<= 1.2), resulting in stored cross-site scripting (XSS). An attacker could inject malicious scripts that are stored and later executed in users' browsers. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring low privileges and user interaction, with a scope change and impacts on confidentiality, integrity, and availability at a low level.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to information disclosure, modification of data, or disruption of service. The impact is rated as medium severity with partial loss of confidentiality, integrity, and availability. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor for vendor updates. Until a fix is available, consider applying input validation or output encoding workarounds if feasible to mitigate stored XSS risks.
