Critical 9.8
Privilege Escalation via Token Endpoint in WSO2 API Manager (APIM 4.x/IS as Resident Key Manager)
This issue only impacts deployments where WSO2 Identity Server is configured as a Resident Key Manager with database sharing. In such environments, a self-registered user may gain access to the System REST APIs of WSO2 API Manager by obtaining a token from th…

Critical 9.4
Broken Access Control via System REST APIs in Multiple WSO2 Products Allows Unauthorized Administrative Actions
The System REST APIs do not correctly enforce access control mechanisms, allowing users with lower privilege roles to execute administrative actions that should be restricted. This weakness permits unauthorized operations on the affected product. Successful e…

Critical 9.1
Remote Code Execution via JDBC User Store Configuration in Multiple WSO2 Products Allows Arbitrary Code Execution
The Management Console fails to properly validate input related to the configuration of JDBC user stores. This weakness allows an attacker to supply specially crafted input that can lead to the execution of arbitrary code on the affected server. Successful ex…

Critical 9.1
Arbitrary File Upload via System REST API in Multiple WSO2 Products Allows Remote Code Execution
The System REST API accepts user-supplied file uploads without enforcing sufficient validation on the file type or destination, allowing files to be written to arbitrary server-accessible locations. Exploitation requires authenticated administrative access wi…

Critical 9.0
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…

Critical 10.0
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 acce…

Critical 9.8
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, potential…
-
Critical 9.4
Account Takeover via Conditional Authentication Script Logic in Multiple WSO2 Products
The Conditional Authentication (Adaptive Authentication) script does not correctly enforce the completion of all required authentication steps when a specific multi-step pattern involving certain authenticators is configured. This allows an attacker to bypass…
-
Critical 9.1
Authenticated arbitrary file upload via a System REST API requiring administrator permission.
A malicious actor with administrative privileges can upload an arbitrary file to a user-controlled location within the deployment via a system REST API. Successful uploads may lead to remote code execution. By leveraging the vulnerability, a malicious actor m…

Critical 9.8
Improper Certificate-Based Authentication Enforcement in Multiple WSO2 Products
A missing authentication enforcement vulnerability exists in the mutual TLS (mTLS) implementation used by System REST APIs and SOAP services in multiple WSO2 products. Due to improper validation of client certificate–based authentication in certain default co…
-
Critical 9.8
Improper Privilege Management in Multiple WSO2 API Manager via keymanager-operations DCR Endpoint
An improper privilege management vulnerability exists in WSO2 API Manager due to missing authentication and authorization checks in the keymanager-operations Dynamic Client Registration (DCR) endpoint. A malicious user can exploit this flaw to generate access…
-
Critical 9.8
Potential Broken Access Control in Multiple WSO2 Products via System REST APIs
Due to an insufficient access control implementation in multiple WSO2 Products, authentication and authorization checks for certain REST APIs can be bypassed, allowing them to be invoked without proper validation. Successful exploitation of this vulnerability…
-
Critical 9.1
An XML External Entity (XXE) vulnerability in Multiple WSO2 Products
Due to the improper configuration of XML parser, user-supplied XML is parsed without applying sufficient restrictions, enabling XML External Entity (XXE) resolution in multiple WSO2 Products. A successful XXE attack could allow a remote, unauthenticated attac…
