Vulnerability from cvelistv5 – Published: 2026-08-27 18:04 – Updated: 2026-08-28 22:47

Title

Spring Authorization Server Default Consent Page is vulnerable to Cross-Site Scripting (XSS)

Summary

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. Spring Authorization Server 1.5.0 - 1.5.8 Spring Authorization Server 1.4.0 - 1.4.11

Severity

8.2 (High)
