What is CVE-2024-5848?

CVE-2024-5848 is a medium-severity cross-site scripting vulnerability in Wso2 Api Manager, published on 27 Feb 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

Official description

A reflected cross-site scripting (XSS) vulnerability exists in multiple WSO2 products due to improper input validation. User-supplied data is directly included in server responses from vulnerable service endpoints without proper sanitization or encoding, allowing an attacker to inject malicious JavaScript.

Successful exploitation could lead to UI manipulation, redirection to malicious websites, or data exfiltration from the browser. While session-related sensitive cookies are protected with the httpOnly flag, mitigating session hijacking risks, the impact may vary depending on gateway-level service restrictions.
