CVE-2023-49802 Information

Description

The LinkedCustomFields plugin for MantisBT allows users to link values between two custom fields creating linked drop-downs. Prior to version 2.0.1 cross-site scripting in the MantisBT LinkedCustomFields plugin allows Javascript execution when a crafted Custom Field is linked via the plugin and displayed when reporting a new Issue or editing an existing one. This issue is fixed in version 2.0.1. As a workaround one may utilize MantisBT’s default Content Security Policy which blocks script execution.
