CVE-2024-34091 — An issue was discovered in Archer Platform 6 before 2024.04

High CVSS 7.3

An issue was discovered in Archer Platform 6 before 2024.04. There is a stored cross-site scripting (XSS) vulnerability. A remote authenticated malicious Archer user could potentially exploit this vulnerability to store malicious HTML or JavaScript code in a trusted application data store. When victim users access the data store through their browsers, the malicious code gets executed in the background of the application and renders content inaccessible. 6.14 P3 (6.14.0.3) is also a fixed release.

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.
