    CVE-2023-49802

    Published: 11 Dec 2023Last Modified: 28 Oct 2026

    Summary: MantisBT LinkedCustomFields Cross-site Scripting vulnerability

    Details: 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.
