CVE-2022-4068 — A user is able to enable their own account if it was disabled by an admin while the user still holds a valid session

High CVSS 7.6

A user is able to enable their own account if it was disabled by an admin while the user still holds a valid session. Moreover, the username is not properly sanitized in the admin user overview. This enables an XSS attack that enables an attacker with a low privilege user to execute arbitrary JavaScript in the context of an admin's account.

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.
