CVE-2022-31690

Spring Security, versions 5.7 prior to 5.7.5, and 5.6 prior to 5.6.9, and
older unsupported versions could be susceptible to a privilege escalation
under certain conditions. A malicious user or attacker can modify a request
initiated by the Client (via the browser) to the Authorization Server which
can lead to a privilege escalation on the subsequent approval. This
scenario can happen if the Authorization Server responds with an OAuth2
Access Token Response containing an empty scope list (per RFC 6749, Section
5.1) on the subsequent request to the token endpoint to obtain the access
token.
