Improper Token Revocation via SOAP Services in Multiple WSO2 Products Allows Retained Access Privileges

When internal roles are removed from a user within the WSO2 product, the system fails to invalidate any previously issued authentication tokens associated with that user. This vulnerability could allow users to retain their previous access privileges even after their roles have been revoked. As a result, a user can continue to perform unauthorized actions or access restricted resources until the expired tokens naturally expire.

Cross-Site Request Forgery via Ajax Processor Endpoints in Multiple WSO2 Products Enables Unauthorized Actions

The Ajax processor within the Carbon console fails to adequately protect state-changing operations from Cross-Site Request Forgery (CSRF) attacks. Specifically, it utilizes the HTTP GET method for these operations, and while the SameSite=Lax cookie attribute is employed for mitigation, this mechanism is bypassed as it permits cookies to be sent with cross-origin top-level navigation requests, including GET requests. This allows an attacker to trick an authenticated user's browser into unknowingl

Improper Implicit Association via User Store Initialization in WSO2 Identity Server [Identity Confusion / External IDP Use]

When secondary user stores are configured, the implicit-association resolver incorrectly initializes from a secondary user store and bypasses the primary user store during search and uniqueness checks. This allows a subject to be associated with an unintended local account if the same lookup claim (e.g., username or email) exists in both the primary and a secondary store. If duplicate claim values exist across user stores, this issue can lead to identity confusion due to incorrect implicit asso

Authorization Code issued for Deleted User reuse in Multiple WSO2 Products Allows Unauthorized Access

Unused authorization codes issued to deleted users are not being properly invalidated or removed from the system. This allows for the persistence of these codes, enabling them to be potentially reused. If an attacker possesses both the authorization code and the associated client credentials (client ID and client secret), they can leverage these unused codes to obtain access tokens on behalf of users who have already been deleted. This may lead to unauthorized access to sensitive resources and

Improper Token Invalidation in WSO2 Identity Server Allows Access After Account Lock

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
