CVE-2023-50069 — WireMock with GUI versions 3.2.0.0 through 3.0.4.0 are vulnerable to stored cross-site scripting (SXSS) through the recording feature

Medium CVSS 6.1

WireMock with GUI versions 3.2.0.0 through 3.0.4.0 are vulnerable to stored cross-site scripting (SXSS) through the recording feature. An attacker can host a malicious payload and perform a test mapping pointing to the attacker's file, and the result will render on the Matched page in the Body area, resulting in the execution of the payload. This occurs because the response body is not validated or sanitized.

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.
