Answer in brief
CVE-2025-8591 records a Medium severity (CVSS 6.1) vulnerability in Reflected Cross-Site Scripting via URL Parameter in Multiple WSO2 Products Enables UI Modification. The current sources do not mark it as known exploited. The current feed maps WSO2/WSO2 API Control Plane (generic), WSO2/WSO2 API Manager (generic), WSO2/WSO2 Identity Server (generic), WSO2/WSO2 Identity Server as Key Manager (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.

The software accepts user-supplied input via a URL parameter without adequate output encoding before reflecting it back to the user's browser. This condition allows an attacker to inject malicious script content into pages served by the application. By leveraging this weakness, an attacker can cause the user's browser to redirect to a malicious website, modify the UI of the webpage, or retrieve information from the browser. However, the impact is mitigated by the use of httpOnly flags on session-related cookies, preventing session hijacking.
