CVE-2024-5848 — A reflected cross-site scripting (XSS) vulnerability exists in multiple WSO2 products due to improper input validation

Medium CVSS 6.1

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.

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
