• CVE-2023-46126: 0.67% estimated exploitation activity in the next 30 days; percentile 52.04 (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 The Fides web application allows users to edit consent and privacy notices such as cookie banners. These privacy notices can then be served by other integrated websites, for example in cookie consent banners. One of the editable fields is a privacy policy URL and this input was found to not be validated. The vulnerability makes it possible to craft a payload in the privacy policy URL which triggers JavaScript execution when the privacy notice is served by an integrated website. The domain scope of the executed JavaScript is that of the integrated website. Exploitation is limited to Admin UI users with the contributor role or higher. Patches The vulnerability has been patched in Fides version 2.22.1. Users are advised to upgrade to this version or later to secure their systems against this threat. Workarounds There are no workarounds.

# Patch Next advisory brief: CVE-2023-46126

Advisory: Fides JavaScript Injection Vulnerability in Privacy Center URL
IDs: CVE-2023-46126, GHSA-fgjj-5jmr-gh83
Record: https://patchnext.com/advisories/cve-2023-46126 (revision 2, source checked 26 Oct 2026, 13:12 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 3.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: ethyca-fides 2.22.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI ethyca-fides: affected < 2.22.1; fixed in 2.22.1

## Suggested inspection (read-only)
- `python -m pip show ethyca-fides`: prints the installed version. Run with the environment that serves production active.

## 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 ethyca-fides.
- 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.
