CVE-2023-49802

The LinkedCustomFields plugin for MantisBT allows users to link values between two custom fields, creating linked drop-d

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.
