NodeJS/oauth2-server/2.4.1

Code Injection in oauth2-server

oauth2-server (aka node-oauth2-server) through 3.1.1 implements OAuth 2.0 without PKCE. It does not prevent authorization code injection. This is similar to CVE-2020-7692. NOTE: the vendor states 'As RFC7636 is an extension, I think the claim in the Readme ofRFC 6749 compliantis valid and not misleading and I also therefore wouldn't describe this as avulnerabilitywith the library per se.'

oauth2-server through 3.1.1 vulnerable to Open Redirect

In oauth2-server (aka node-oauth2-server) through 3.1.1, the value of the redirect_uri parameter received during the authorization and token request is checked against an incorrect URI pattern ([a-zA-Z][a-zA-Z0-9+.-]+:) before making a redirection. This allows a malicious client to pass an XSS payload through the redirect_uri parameter while making an authorization request. NOTE: this vulnerability is similar to CVE-2020-7741.
