• CVE-2023-32193: 0.47% estimated exploitation activity in the next 30 days; percentile 40.47 (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 A vulnerability has been identified in which unauthenticated cross-site scripting (XSS) in Norman's public API endpoint can be exploited. This can lead to an attacker exploiting the vulnerability to trigger JavaScript code and execute commands remotely. The attack vector was identified as a Reflected XSS. Norman API propagates malicious payloads from user input to the UI, which renders the output. For example, a malicious URL gets rendered into a script that is executed on a page. The changes addressed by this fix are: - Encode input that comes from the request URL before adding it to the response. - The request input is escaped by changing the URL construction that is used for links to use url.URL. - The request input is escaped by escaping the JavaScript and CSS variables with attribute encoding as defined by OWASP.

# Patch Next advisory brief: CVE-2023-32193

Advisory: Norman API Cross-site Scripting Vulnerability
IDs: CVE-2023-32193, GHSA-r8f4-hv23-6qp6
Record: https://patchnext.com/advisories/cve-2023-32193 (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: High (CVSS 8.3)
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/norman 0.0.0-20240207153100-3bb70b772b52. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/rancher/norman: affected < 0.0.0-20240207153100-3bb70b772b52; fixed in 0.0.0-20240207153100-3bb70b772b52

## Suggested inspection (read-only)
- Go github.com/rancher/norman: 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/norman.
- 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
