Spring Authorization Server's default consent page renders user-controlled values without HTML entity encoding. When using the DefaultConsentPage, an attacker can craft an OAuth2 authorization request containing a malicious value that is stored server-side and later rendered unencoded in the default consent page presented to the end user.
