Prior to 6.2.0, OpenIdConnectAuth in social_core/backends/open_id_connect.py uses get_and_store_nonce to place the OpenID Connect nonce in a shared OpenIdConnectAssociation table, and get_nonce and validate_claims verify only that the nonce exists and has not expired rather than binding it to the browser session and OAuth state that initiated the login. An attacker who obtains a victim&#39;s unused authorization code can start a separate login to obtain valid state for the attacker&#39;s browser, submit the victim&#39;s code with that state, and pass nonce validation because the victim nonce is globally available. With DEFAULT_USE_PKCE disabled in the default OpenIdConnectAuth configuration, the attacker can be logged in as the victim. This issue is fixed in version 6.2.0.</p> <p><strong>Affected:</strong> python-social-auth social-core</p> <p>Python Social Auth is a social authentication and registration mechanism.
