Description

Summary

Several cross-site scripting vulnerabilities existed in the deno_doc crate which lead to Self-XSS with deno doc --html.

Details & PoC

1.) XSS in generated search_index.js

deno_doc outputed a JavaScript file for searching. However, the generated file used innerHTML on unsanitzed HTML input.

https://github.com/denoland/deno_doc/blob/dc556c848831d7ae48f3eff2ababc6e75eb6b73e/src/html/templates/pages/search.js#L120-L144

2.) XSS via property, method and enum names

deno_doc did not sanitize property names, method names and enum names.

Impact

The first XSS most likely didn't have an impact since deno doc --html is expected to be used locally with own packages.
