Summary
Fides JavaScript Injection Vulnerability in Privacy Center URL
Workarounds
There are no workarounds.
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.
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.
CVE-2023-46126 has a CVSS score of 3.9 (Low). The vector is network-reachable, high privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.22.1); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2023-46126? CVE-2023-46126 is a low-severity cross-site scripting (XSS) vulnerability in ethyca-fides (pip), affecting versions < 2.22.1. It is fixed in 2.22.1. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- How severe is CVE-2023-46126? CVE-2023-46126 has a CVSS score of 3.9 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of ethyca-fides are affected by CVE-2023-46126? ethyca-fides (pip) versions < 2.22.1 is affected.
- Is there a fix for CVE-2023-46126? Yes. CVE-2023-46126 is fixed in 2.22.1. Upgrade to this version or later.
- Is CVE-2023-46126 exploitable, and should I be worried? Whether CVE-2023-46126 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2023-46126 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2023-46126? Upgrade
