The OpenID Connect server implementation for MITREid Connect through 1.3.3 contains a Server Side Request Forgery (SSRF) vulnerability. The vulnerability arises due to unsafe usage of the logo_uri parameter in the Dynamic Client Registration request. An unauthenticated attacker can make a HTTP request from the vulnerable server to any address in the internal network and obtain its response (which might, for example, have a JavaScript payload for resultant XSS). The issue can be exploited to bypass network boundaries, obtain sensitive data, or attack other hosts in the internal network.

aurelia-path is part of the Aurelia platform and contains utilities for path manipulation. There is a prototype pollution vulnerability in aurelia-path before version 1.1.7. The vulnerability exposes Aurelia application that uses `aurelia-path` package to parse a string. The majority of this will be Aurelia applications that employ the `aurelia-router` package. An example is this could allow an attacker to change the prototype of base object class `Object` by tricking an application to parse the following URL: `https://aurelia.io/blog/?__proto__[asdf]=asdf`. The problem is patched in version `1.1.7`.

This affects all versions of package notevil; all versions of package argencoders-notevil. It is vulnerable to Sandbox Escape leading to Prototype pollution. The package fails to restrict access to the main context, allowing an attacker to add or modify an object's prototype. **Note:** This vulnerability derives from an incomplete fix in [SNYK-JS-NOTEVIL-608878](https://security.snyk.io/vuln/SNYK-JS-NOTEVIL-608878).

DOMPurify is a DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, MathML and SVG. DOMPurify was vulnerable to prototype pollution. This vulnerability is fixed in 2.4.2.
