Whilst using the Source Mapper extension in BurpSuite we noticed a few bugs and some opportunities for improvements. You can read more about the plugin in our earlier blog post. The improvements in this version include:
- More granular configuration
- Defaulting to injecting a SourceMap HTTP header instead of the SourceMap content comment in order to prevent conflicts with Sub-Resource Integrity (SRI) hashes
- It now also does CSS file source map injection
In principal this Burp Extension enables the workflow as it previously did, just now with fewer bugs and more configuration options.
You will find the source code here:
It will also be integrated in the Burp Suite BApp store any day now.
And credit where it is due..! This version of the extension was led by Mia.
