Old response in Repeater if a custom tab is selected

Tomáš | Last updated: Jun 13, 2023 02:26PM UTC

Hi, I've been working on an extension for Burp and noticed if you have a custom tab selected (IMessageEditorTab) in Repeater for a response and you issue a different request, the old response is still shown in all the tabs for the response. You can try it for example with a popular extension JSON Web Tokens: 1) Go to Repeater 2) Visit https://pastebin.com/raw/ankfyFGN and notice e.g. the Date header 3) Select the JSON Web Tokens extension in the response 4) Change the request to https://pastebin.com/raw/hhuPwhz5 5) Observe you still have the old response in all the tabs (e.g. by looking at the Date header in the Raw tab)

Hi. Thanks for this information. We've replicated this issue and raised a bug report for this behavior. We're looking into getting this resolved. If there's anything else we can help with, then please let us know.

Hi We wanted to update the thread to inform everyone that we have released a fix for this issue (The extension-generated editor tab does not get updated with new content) in Early Adopter v2023.7.
