Summary

Impact A vulnerability has been identified within Rancher UI that allows a malicious actor to perform a Stored XSS attack through the cluster description field. Please consult the associated MITRE ATT&CK - Technique - Drive-by Compromise for further information about this category of attack. Patches The fix introduces new changes in the directives responsible for sanitizing HTML code before rendering. We replaced the v-tooltip directive with the v-clean-tooltip directive. Patched versions include releases 2.9.4 and 2.10.0. Workarounds There are no workarounds for this issue. Users are recommended to upgrade, as soon as possible, to a version of /Rancher Manager which contains the fixes. Credits This issue was identified and reported by Bhavin Makwana from Workday’s Cyber Defence Team.

Impact

What is cross-site scripting (XSS)?

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.

Severity and exposure

CVE-2024-52281 has a CVSS score of 8.9 (High). The vector is network-reachable, low 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 (2.9.4). 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 instead of chasing every advisory.

Kodem's runtime-powered SCA identifies whether CVE-2024-52281 is reachable in your applications. Explore open-source security for your team.

CVE-2024-52281 is a high-severity cross-site scripting (XSS) vulnerability in github.com/rancher/rancher (go), affecting versions >= 2.9.0, < 2.9.4. It is fixed in 2.9.4. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.

How severe is CVE-2024-52281?

CVE-2024-52281 has a CVSS score of 8.9 (High). 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 github.com/rancher/rancher are affected by CVE-2024-52281?

github.com/rancher/rancher (go) versions >= 2.9.0, < 2.9.4 is affected.

Is there a fix for CVE-2024-52281?

Yes. CVE-2024-52281 is fixed in 2.9.4. Upgrade to this version or later.

Is CVE-2024-52281 exploitable, and should I be worried?

Whether CVE-2024-52281 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-2024-52281 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-2024-52281?

Upgrade github.com/rancher/rancher to 2.9.4 or later.
