Vulnerability Title
Novu Open Redirect Vulnerability in Sign-In with GitHub Functionality
Source: CVE Program / CVE List V5
Vulnerability Description
Novu provides an API for sending notifications through multiple channels. Versions prior to 0.16.0 contain an open redirect vulnerability in the "Sign In with GitHub" functionality of Novu's open-source repository. It could have allowed an attacker to force a victim into opening a malicious URL and thus, potentially log into the repository under the victim's account gaining full control of the account. This vulnerability only affected the Novu Cloud and Open-Source deployments if the user manually enabled the GitHub OAuth on their self-hosted instance of Novu. Users should upgrade to version 0.16.0 to receive a patch.
