CVE-2024-27140 — Apache Archiva security vulnerability

Medium CVSS 5.4

** UNSUPPORTED WHEN ASSIGNED ** Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Apache Archiva. This issue affects Apache Archiva: from 2.0.0. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users. Alternatively, you could configure a HTTP proxy in front of your Archiva instance to only forward requests that do not have malicious characters in the URL. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

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.
