CVE-2022-43760 is a medium-severity cross-site scripting (XSS) vulnerability in github.com/rancher/rancher (go), affecting versions >= 2.6.0, < 2.6.13. It is fixed in 2.6.13, 2.7.4.
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 targeted their Rancher instance, we recommend rotating all API Keys and Kubeconfig tokens. It's also advised to review logs and possibly rotate credentials stored as secrets in Rancher and downstream cluster, if you believe that users' credentials to access Rancher and its clusters might have been compromised. Patches Patched versions include releases 2.6.13, 2.7.4 and later versions. Workarounds There is no direct mitigation besides updating Rancher to a patched version.

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-2022-43760 has a CVSS score of 8.4 (Medium). 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 (2.6.13, 2.7.4). Upgrading removes the vulnerable code path.

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-2022-43760 is reachable in your applications. Explore open-source security for your team.

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.
