CVE-2026-2445: WSO2 multiple products reflected XSS via URL parameter

CVE-2026-2445 · Severity: medium · CVSS 6.1 · Published 2026-07-20

WSO2 API and Identity management products are affected by a security flaw that allows attackers to run malicious scripts in a user's web browser. By tricking a user into clicking a specially crafted link, an attacker could redirect them to a fake website or modify what they see on the page. While the risk of full account takeover is reduced because session cookies are protected, the flaw could still be used for phishing or to steal other information visible in the browser.

Technologies: Wso2 API Control Plane, Wso2 API Manager, Wso2 Identity Server. Vendors: Wso2.

Technical details

A reflected cross-site scripting (XSS) vulnerability exists in multiple WSO2 products due to improper neutralization of user-supplied input in URL parameters. An unauthenticated remote attacker can exploit this by inducing a user to visit a malicious URL, leading to the execution of arbitrary JavaScript in the context of the victim's browser session. This can result in UI redressing, unauthorized redirection, or the theft of non-httpOnly browser data. The impact on session hijacking is mitigated by the use of the httpOnly flag on sensitive cookies. Patches are available via WSO2 updates or specific version increments.
