@ehsandeep I am able to reproduce the issue. I am using alpine linux docker container which installs the latest version of go (apk add go) and Nuclei as per Nuclei documentation.

@Teicu , I have uploaded fix along with other edge cases to issue-2979-url-panic branch . can you try installing nuclei again with following command

go install -v  github.com/projectdiscovery/nuclei/v2/cmd/nuclei@issue-2979-url-panic 

and share if you are facing same issue .
