## What it is
HTTPLeaks is a single HTML file that enumerates all known ways a website can inadvertently leak HTTP requests through HTML elements and attributes. It is maintained by Cure53 and serves as a reference test page for detecting CSP bypasses and privacy leaks.

## Use cases
- test a browser's Content Security Policy for leak vectors
- check a webmail client for HTTP request leaks in HTML emails
- audit a web proxy for unrewritten resource-fetching elements
- verify that sanitized HTML does not fire external requests
- research which HTML elements and attributes can fetch external resources

## When to choose
- you need a comprehensive, community-maintained test page for HTTP leak vectors
- you are evaluating CSP implementations or HTML sanitizers
- you audit web proxies or webmail clients for privacy leaks

## When to avoid
- you need an automated security scanner rather than a manual test page
- you want a library or API to integrate into a test suite
- you need general vulnerability scanning beyond HTTP leak vectors

## Facets
- artifact type: dataset
- maturity: maintenance
- function: security, testing, browser-extension
- domain: security, web-development, privacy, developer-tools
- platform: browser
