Access Control Bypass via Publisher REST APIs in Multiple WSO2 Products Allows Cross-Tenant Operations

In multi-tenant deployments, the Publisher REST APIs fail to enforce tenant isolation correctly. This allows a user in one tenant, possessing sufficient privileges to invoke these APIs, to perform operations that impact other tenants. The vulnerability allows a privileged user to perform publisher operations such as exposing or modifying API Metadata in another tenant environment. This impact is only realized in multi-tenant deployments.

Authentication Bypass via JWT Algorithm Mismatch in Multiple WSO2 Products Allows Account Takeover

The JWT authentication mechanism accepts tokens signed with algorithms other than those explicitly configured or supported. This allows an attacker to craft a JWT with an unsupported algorithm, which is then incorrectly validated, leading to unauthorized access. Successful exploitation of this vulnerability may result in unauthorized access to the system, including the potential compromise of administrative accounts and full account takeover. The CVSS score is adjusted to 9.8 (CVSS:3.1/AV:N/AC:

Privilege Escalation via System REST APIs in Multiple WSO2 Products Permits Admin Account Takeover

Tokens issued to a low-privileged user are not sufficiently restricted, allowing them to be used to access product-level Admin REST APIs. Exploitation of this vulnerability allows a low-privileged user to invoke the Admin REST APIs of WSO2 products, potentially leading to full administrative account takeover. This requires the attacker to already possess a low-privileged user account and be able to obtain a valid token for it.

Improper Access Control via Gateway API in Multiple WSO2 Products Allows Unauthorized Operations

The software fails to enforce role-based access controls for certain Gateway API invocations. Users with the 'Internal/Everyone' role can invoke these APIs, bypassing intended permission checks. This same vulnerability also affects Internal Service APIs, potentially exposing them in WSO2 APIM 3.x versions. A malicious actor with a valid user account on a vulnerable deployment can perform sensitive operations against the Gateway REST API regardless of their actual roles or privileges. This could
