DescriptionCVE.org

In versions of Spring Authorization Server 1.5.0 through 1.5.7, the authorization endpoint performs insufficient validation of the request_uri parameter. An attacker can craft a request containing an invalid request_uri paired with an unvalidated redirect_uri, which can result in an open redirect to an attacker-controlled site.

AnalysisAI

Open redirect in Spring Authorization Server 1.5.0-1.5.7 allows remote unauthenticated attackers to redirect victims to attacker-controlled sites by crafting authorization requests that pair an invalid request_uri with an unvalidated redirect_uri. The CVSS scope change (S:C) reflects that the redirect escapes the authorization server's security boundary, enabling high-trust phishing attacks because victims see the legitimate authorization server domain before being redirected. …

Risk Assessment CVSS 6.1 (Medium) with vector AV:N/AC:L/PR:N/UI:R/S:C correctly captures a network-exploitable, unauthenticated flaw of low operational complexity, but one gated on user interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade Spring Authorization Server to a version beyond 1.5.7 per the vendor advisory at https://spring.io/security/cve-2026-59355 - the exact fixed version is not specified in available intelligence and must be confirmed directly from the advisory before deployment. … Detailed patch versions, workarounds, and compensating controls in full report.
