"Angular is a development platform for building mobile and desktop web
applications using TypeScript/JavaScript and other languages. Prior to
versions 19.2.16, 20.3.14, and 21.0.1, there is a XSRF token leakage
via protocol-relative URLs in angular HTTP clients. The vulnerability
is a Credential Leak by App Logic that leads to the unauthorized
disclosure of the Cross-Site Request Forgery (XSRF) token to an
attacker-controlled domain. Angular's HttpClient has a built-in XSRF
protection mechanism that works by checking if a request URL starts
with a protocol (http:// or https://) to determine if it is cross-
origin. If the URL starts with protocol-relative URL (//), it is
incorrectly treated as a same-origin request, and the XSRF token is
automatically added to the X-XSRF-TOKEN header. This issue has been
patched in versions 19.2.16, 20.3.14, and 21.0.1. A workaround for
this issue involves avoiding using protocol-relative URLs (URLs
starting with //) in HttpClient requests. All backend communication
URLs should be hardcoded as relative paths (starting with a single /)
or fully qualified, trusted absolute URLs.

This plugin only works with Tenable.ot.
