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 · unedited
Active access tokens are not revoked or invalidated when a user account is locked within WSO2 Identity Server. This failure to enforce revocation allows previously issued, valid tokens to remain usable, enabling continued access to protected resources by locked user accounts. The security consequence is that a locked user account can maintain access to protected resources through the use of existing, unexpired access tokens. This creates a security gap where access control policies are bypassed, potentially leading to unauthorized data access or actions until the tokens naturally expire.

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 · high confidence

In WSO2 Identity Server, the account lockout mechanism fails to revoke active OAuth2/OIDC access tokens when a user account is locked. This occurs because token validity checking does not query the account lock status, allowing previously issued tokens to remain valid and usable until natural expiration, bypassing access control policies.

MitigationImplement token revocation checks that query account lock status during token validation, or trigger automatic token invalidation through the token management API when an account is locked.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed WSO2 Identity Server version
    Locate the version file in the WSO2 installation directory, typically in the product.xml or carbon.xml file found in the repository/conf directory, or check the product version displayed in the management console under About section
    Affected if The installed version is exactly 5.2.0
  2. Verify OAuth2/OIDC is enabled
    Check the deployment.toml file in the repository/conf directory for OAuth2 or OIDC configurations, look for sections like [oauth] or [oidc] that indicate these protocols are configured
    Affected if OAuth2 or OIDC authentication flows are enabled in the configuration
  3. Confirm account lockout is configured
    Inspect the identity-mgt.properties file or the account lockout configuration section in deployment.toml to verify that account lockout functionality is turned on
    Affected if Account lockout policy is enabled for user authentication attempts
  4. Test token validity after account lock
    Obtain a valid OAuth2 access token for a test user, then lock that user account through the management console or API, and attempt to use the existing token to access a protected resource
    Affected if The previously issued token continues to work after the account is locked, demonstrating tokens are not invalidated upon account lock

You are affected if running WSO2 Identity Server version 5.2.0 with OAuth2/OIDC enabled and account lockout configured, where tokens remain usable after user accounts are locked.
