Impact

Attackers can steal session cookies, redirect users to malicious sites, deface content, or perform actions on behalf of authenticated users. With a CVSS score of 4.3 (MEDIUM), this represents a moderate risk.
Exploit ScenarioDerived

An attacker injects a JavaScript payload into a vulnerable input field. When another user views the page, the script executes in their browser, stealing their session token.

AnalysisAIv1 – Mar 14, 2026

A stored cross-site scripting (XSS) vulnerability exists in the Management Console of multiple WSO2 products due to insufficient input validation in the Rich Text Editor within the registry section. To exploit this vulnerability, a malicious actor must have a valid user account with administrative access to the Management Console. If successful, the actor could inject persistent JavaScript payloads, enabling the theft of user data or execution of unauthorized actions on behalf of other users.

While this issue enables persistent client-side script execution, session-related cookies remain protected with the httpOnly flag, preventing session hijacking.

RemediationAI

Encode all user-supplied output contextually (HTML, JS, URL). Implement Content Security Policy (CSP) headers. Use HTTPOnly and Secure cookie flags.
