AI-Generated

The Spring Authorization Server's default consent page is vulnerable due to improper HTML entity encoding of user-controlled values, allowing attackers to inject malicious content into OAuth2 authorization requests. This could lead to cross-site scripting (XSS) attacks, compromising user data and potentially allowing unauthorized actions. Organizations utilizing Spring Authorization Server versions 1.4.0 to 1.5.8 should prioritize patching this vulnerability to safeguard their applications and users.
