Strapi is an open-source content management system. By combining two vulnerabilities (an Open Redirect
and session token sent as URL query parameter
) in @strapi/plugin-users-permissions before version 4.24.2, is its possible of an unauthenticated attacker to bypass authentication mechanisms and retrieve the 3rd party tokens. The attack requires user interaction (one click). Unauthenticated attackers can leverage two vulnerabilities to obtain an 3rd party token and the bypass authentication of Strapi apps. Users should upgrade @strapi/plugin-users-permissions to version 4.24.2 to receive a patch.
A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
