The package koa-remove-trailing-slashes before 2.0.2 are vulnerable to Open Redirect via the use of trailing double slashes in the URL when accessing the vulnerable endpoint (such as https://example.com//attacker.example/). The vulnerable code is in index.js::removeTrailingSlashes(), as the web server uses relative URLs instead of absolute URLs.

Spring Security OAuth versions 2.3 prior to 2.3.6, 2.2 prior to 2.2.5, 2.1 prior to 2.1.5, and 2.0 prior to 2.0.18, as well as older unsupported versions could be susceptible to an open redirector attack that can leak an authorization code. A malicious user or attacker can craft a request to the authorization endpoint using the authorization code grant type, and specify a manipulated redirection URI via the redirect_uri parameter. This can cause the authorization server to redirect the resource owner user-agent to a URI under the control of the attacker with the leaked authorization code.

An issue in Outline <= v0.76.1 allows attackers to redirect a victim user to a malicious site via intercepting and changing the state cookie.

In OAuth2 Proxy from version 5.1.1 and less than version 6.0.0, users can provide a redirect address for the proxy to send the authenticated user to at the end of the authentication flow. This is expected to be the original URL that the user was trying to access. This redirect URL is checked within the proxy and validated before redirecting the user to prevent malicious actors providing redirects to potentially harmful sites. This has been fixed in version 6.0.0.

An open redirect vulnerability in the administrative interface of the B. Braun Melsungen AG SpaceCom device Version L81/U61 and earlier, and the Data module compactplus Versions A10 and A11 allows attackers to redirect users to malicious websites.
