CVE-2022-43758 is a medium-severity command injection vulnerability in github.com/rancher/rancher (go), affecting versions >= 2.5.0, < 2.5.17. It is fixed in 2.5.17, 2.6.10, 2.7.1.
Impact An issue was discovered in Rancher from versions 2.5.0 up to and including 2.5.16, 2.6.0 up to and including 2.6.9 and 2.7.0, where a command injection vulnerability is present in the Rancher Git package. This package uses the underlying Git binary available in the Rancher container image to execute Git operations. Specially crafted commands, when not properly disambiguated, can cause confusion when executed through Git, resulting in command injection in the underlying Rancher host. This issue can potentially be exploited in Rancher in two ways: Adding an untrusted Helm catalog, in the Catalogs menu, that contains maliciously designed repo URL configuration in Helm charts. Modifying the URL configuration used to download KDM (Kontainer Driver Metadata) releases. By default, only the Rancher admin has permission to manage both configurations for the local cluster (the cluster where Rancher is provisioned). Note: More information about this category of issue in version control system (VCS) tools are available in Snyk's blog post. Workarounds Except for only adding trusted catalogs and the KDM URL to Rancher, there is no other workaround besides updating Rancher to a patched version. Patches Patched versions include releases 2.5.17, 2.6.10, 2.7.1 and later versions. It is also important to update to a patched version in case Rancher or its standalone Git package implementation is used as a Go library instead of the application itself. Otherwise, this vulnerability might affect your dependent code.

Verify our support matrix and product support lifecycle.
Untrusted input is inserted into a command that is later executed by the application, allowing the attacker to alter the intent of that command. Typical impact: arbitrary command execution in the application's environment.
CVE-2022-43758 has a CVSS score of 6.8 (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 (2.5.17, 2.6.10, 2.7.1). 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.

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.
