• CVE-2022-43760: 0.71% estimated exploitation activity in the next 30 days; percentile 53.77 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact Multiple Cross-Site Scripting (XSS) vulnerabilities have been identified in the Rancher UI. Cross-Site scripting allows a malicious user 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. The affected areas include the Projects/Namespaces and Auth Provider sections. The attacker needs to be authenticated and have write access to those features in order to exploit the vulnerabilities. Some of the permissions (roles) required are: - Project Owner. - Restricted Admin. - Configure Authentication. - Administrator. - Custom RBAC Role that provides write access on Projects or External Authentication Providers. For users that suspect this vulnerability may have…

# Patch Next advisory brief: CVE-2022-43760

Advisory: Rancher UI has multiple Cross-Site Scripting (XSS) issues
IDs: CVE-2022-43760, GHSA-46v3-ggjg-qq3x
Record: https://patchnext.com/advisories/cve-2022-43760 (revision 1, source checked 26 Oct 2026, 15:05 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/rancher/rancher 2.7.4, 2.6.13. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/rancher/rancher: affected >= 2.6.0, < 2.6.13; >= 2.7.0, < 2.7.4; fixed in 2.6.13, 2.7.4

## Suggested inspection (read-only)
- Go github.com/rancher/rancher: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/rancher/rancher.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-46v3-ggjg-qq3x (GitHub-reviewed advisory GHSA-46v3-ggjg-qq3x lists affected ranges: Go github.com/rancher/rancher >=2.6.0 =2.7.0 <2.7.4)
