CVE-2025-55469
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIncorrect access control in youlai-boot v2.21.1 allows attackers to escalate privileges and access the Administrator backend.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceyoulai-boot v2.21.1 contains an incorrect access control vulnerability that allows unauthenticated or low-privilege attackers to escalate their privileges and gain unauthorized access to the Administrator backend. The CVSS 9.8 score indicates complete compromise of confidentiality, integrity, and availability via this privilege escalation flaw.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed youlai-boot versionCheck the application JAR/WAR file manifest, pom.xml dependency version, or the boot log output at startup for the exact youlai-boot version numberAffected if The installed version is exactly 2.21.1
-
Locate authentication configurationInspect the security configuration files such as SecurityConfig.java, WebSecurityConfig.java, or application.yml/properties files for role-based access control (RBAC) definitions and endpoint access rulesAffected if No role-based access control rules are defined or admin endpoints lack explicit role requirements
-
Test admin endpoint accessibilitySend unauthenticated or low-privilege HTTP requests to known admin paths such as /admin/, /system/, or /manage/ and observe if access is granted without authentication credentialsAffected if Admin endpoints respond with successful access (200 OK) when requested without valid authentication tokens or session cookies
-
Review authentication filter chainExamine the Spring Security filter chain configuration in the application codebase, specifically looking for filter order, permitAll() rules, and authorization configurations for privileged pathsAffected if Security filters permit unauthenticated access to administrative routes or lack proper authorization checks before executing privileged operations
-
Check user role assignment logicInspect the code that handles role assignment or privilege elevation, looking for any logic that assigns Administrator roles without proper validation or role verificationAffected if The codebase contains logic that allows automatic role escalation or assigns elevated privileges based on insecure conditions
The environment is affected if youlai-boot version 2.21.1 is running AND admin endpoints are accessible without proper authentication or low-privilege users can escalate to Administrator access.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to a patched version of youlai-boot if available; otherwise, implement proper role-based access control (RBAC) checks on all administrative endpoints and verify authentication middleware is correctly enforced across all privileged paths.
