spring-security-oauth2-authorization-server is vulnerable to Cross-Site Scripting (XSS)
82
High Risk
This Affects:
spring-security-oauth2-authorization-serverTL;DR
spring-security-oauth2-authorization-server default consent page renders user-controlled OAuth2 values without HTML entity encoding. An attacker can store a malicious value in an authorization request and have it execute in the consent page shown to the end user. Custom consent pages configured with consentPage(...) are not affected. The patch encodes those values before rendering.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you use the default OAuth2 consent page.
Background info
spring-security-oauth2-authorization-server is vulnerable to Cross-Site Scripting (XSS) in versions 7.0.0 - 7.0.6 and 7.1.0 - 7.1.0.
How to fix this
Upgrade the org.springframework.security:spring-security-oauth2-authorization-server library to the patch version.
