Stored script execution via undisclosed input handling

Published Dec 21, 2023 · Updated May 20, 2026

Stored cross-site scripting in Uyumsoft LioXERP before 146 allows remote authenticated users to execute script in another user’s browser. Public records do not identify the affected input, storage field, rendering path, or missing output-encoding operation. Exploitation requires an authenticated user to store attacker-controlled content and another user to view it, limiting execution to the viewer’s browser context.
