Vulnerability CVE-2023-49802
Published: 2023-12-11   Modified: 2023-12-14

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.

Type:

CWE-79

 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'))

Affected software
Mantisbt -> Linked custom fields
