Error Message Checks
Summary: PortSwigger's BApp Store lists a Burp Suite extension called Error Message Checks, version 2.0.5, authored by August Detlefsen and last updated 15 August 2023, which passively reports detailed server error messages that are often not visible during normal testing. The listing rates its overall system impact as Medium and notes that extensions are written by third-party Burp users, with PortSwigger making no warranty about their quality or usefulness for any particular purpose.
Bottom line: Detailed server error messages routinely leak stack traces, paths, and internal detail, and this extension exists because those messages stay hidden during ordinary testing - meaning they can sit exposed in production until someone looks for them deliberately.
