CVE-2026-2053

Severity CVSS v4.0:
Pending analysis
Type:
CWE-918 Server-Side Request Forgery (SSRF)
Publication date:
26/06/2026
Last modified:

Description

The WSO2 API Manager&amp;#39;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.<br /> <br /> 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.
