# cordova-plugin-advanced-http: redirects leak session cookies to third-party hosts

cordova-plugin-advanced-http versions 1.5.0 through 3.3.1 forward Cookie headers to other hosts when a request is redirected. An attacker who controls or influences a redirect can capture the user's cookies and hijack their sessions.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed version in the project's `package.json` or `config.xml` for `cordova-plugin-advanced-http` between `1.5.0` and `3.3.1`
- Look for `cordova-plugin-advanced-http` in `package-lock.json` or `yarn.lock` to confirm the resolved version

## Fix

- `cordova-plugin-advanced-http`: move to a version later than `3.3.1` (the advisory's patch link is on GitHub; the exact fixed version is unknown from the sources)

## Documents

- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/cordova-plugin-advanced-http-through-3.3.1-cookie-leak-via-cross-origin-redirects
- [fix] Patch: github.com https://github.com/silkimen/cordova-plugin-advanced-http/commit/777a6f10939fd76ddf7f9fe029ae3fcaed850ca1

## From the sources

cordova-plugin-advanced-http 1.5.0 through 3.3.1 contains an information disclosure vulnerability that leaks cookies to third-party hosts because the JavaScript layer passes jar-built Cookie headers as ordinary request headers. When a request is redirected to another host via an open or attacker-influenced redirect, native iOS and Android stacks forward the Cookie header, letting attackers hijack user sessions.
