How to Fix CVE-2024-32468

To remediate this vulnerability, upgrade all affected Deno doc dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

deno_doc fixed: 0.119.0 
Upgrade deno_doc to 0.119.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for deno_doc

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-32468, inspect your project dependencies for Deno doc:

inspect dependencies for deno_doc

Analyze the terminal output to locate any version of Deno doc in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.119.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Deno doc, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
