CVE-2024-4867

Severity CVSS v4.0:
Pending analysis
Type:
CWE-79 Cross-Site Scripting (XSS)
Publication date:
16/04/2026
Last modified:

Description

The WSO2 API Manager developer portal accepts user-supplied input without enforcing expected validation constraints or proper output encoding. This deficiency allows a malicious actor to inject script content that is executed within the context of a user&amp;#39;s browser.<br /> <br /> By leveraging this cross-site scripting vulnerability, a malicious actor can cause the browser to redirect to a malicious website, make changes to the UI of the web page, or retrieve information from the browser. However, session hijacking is not possible as all session-related sensitive cookies are protected by the httpOnly flag.
