CVE-2022-43760 — Suse Rancher security vulnerability

High CVSS 8.4

An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in SUSE Rancher allows users in some higher-privileged groups to to inject code that is executed within another user's browser, allowing the attacker to steal sensitive information, manipulate web content, or perform other malicious activities on behalf of the victims. This could result in a user with write access to the affected areas being able to act on behalf of an administrator, once an administrator opens the affected web page. This issue affects Rancher: from >= 2.6.0 before < 2.6.13, from >= 2.7.0 before < 2.7.4.

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.
