Detailsinfo

A vulnerability was found in WSO2 API Manager up to 3.0.x and classified as critical. This issue affects some unknown processing of the component Destination Handler. The manipulation with an unknown input leads to a server-side request forgery vulnerability. Using CWE to declare the problem leads to CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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 arbitrary destinations for server-initiated requests. Successful exploitation allows an unauthenticated attacker to control the destination of server-initiated requests originating from the WSO2 API Manager. This direct control can enable unauthorized access to internal network resources or services that would typically be inaccessible from external networks.

It is possible to read the advisory at security.docs.wso2.com. The identification of this vulnerability is CVE-2026-2053 since 02/06/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available.

Upgrading to version 3.1.0, 3.1.0.360, 3.2.0.465, 3.2.1.84, 4.0.0.385 or 4.2.0.189 eliminates this vulnerability.
