CVE-2023-31180Network attack vector

Unauthenticated browser script execution

Published May 8, 2023 · Updated Jan 29, 2025

Reflected XSS in Wjj Software InnoKB Server 2.2.1 through 2.2.2 allows remote attackers to execute script in a user’s browser. The CNA and vendor do not identify the request, parameter, or response-generation path that reflects untrusted input without safe output encoding. Exploitation is unauthenticated over the network but requires a user to follow a crafted request, allowing script execution in that user’s web context.
