WSO2 API Manager: Improper Privilege Management
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, potentiall
- 9.4 Critical severity
WSO2 Identity Server: Protection Mechanism Failure
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
- 7.5 High severity
WSO2 Enterprise Integrator: Protection Mechanism Failure
The account locking mechanism fails to trigger when secondary user stores are inaccessible. The software does not maintain a consistent state for account locking if it cannot reach all configured user stores, allowing an attacker to repeatedly attempt authenti
- 8.6 High severity
WSO2 Universal Gateway: Improper Neutralization
The throttling event handling mechanism in multiple WSO2 products accepts user-supplied JSON payloads without sufficient validation of their structure and content. This allows an unauthenticated remote attacker to inject malicious JSON data that can lead to a
- 7.3 High severity
WSO2 Identity Server: Authentication Bypass Using an Alternate Path or Channel
In multi-tenanted deployments, the application consent management mechanism fails to correctly isolate consent scopes between tenants. Consent granted by a user for a specific SaaS application within one tenant can be incorrectly applied to SaaS applications w
- 10.0 Critical severity
WSO2 API Manager: Server-Side Request Forgery
The WSO2 API Manager's message flow component, when processing WS-Addressing headers, does not sufficiently validate or restrict user-controlled input within these headers. This omission allows an attacker to manipulate WS-Addressing headers to specify arbitra
- 8.8 High severity
WSO2 API Control Plane: Improper Preservation of Permissions
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, poten
- 7.5 High severity
WSO2 API Manager: Improper Neutralization of Special Elements in Output Used by a Downstream Component
In Webhook API invocations, the component accepts user-supplied input for HTTP request headers without sufficient validation or sanitization, allowing these headers to be injected into HTTP responses. By exploiting this vulnerability, a malicious actor can inj
- 7.5 High severity
WSO2 API Manager: Improper Restriction of XML External Entity Reference
The component accepts XML input through the publisher without disabling external entity resolution. This allows malicious actors to submit a crafted XML payload that exploits the unescaped external entity references. By leveraging this vulnerability, a malicio
- 9.1 Critical severity
WSO2 API Manager: Improper Restriction of XML External Entity Reference
The XML parsers within multiple WSO2 products accept user-supplied XML data without properly configuring to prevent the resolution of external entities. This omission allows malicious actors to craft XML payloads that exploit the parser's behavior, leading to
- 8.1 High severity
WSO2 API Manager: Authentication Bypass by Spoofing
When the "Silent Just-In-Time Provisioning" feature is enabled for a federated identity provider (IDP) there is a risk that a local user store user's information may be replaced during the account provisioning process in cases where federated users share the s
