CVE-2022-43756Network attack vector

Authenticated resource exhaustion via unvalidated Git credentials

Published Feb 7, 2023 · Updated Mar 25, 2025

Injection in Rancher Wrangler allows remote authenticated users to exhaust CPU and memory via crafted Git credentials. The Git command wrapper interpolates the password into an unquoted shell command and passes repository fields without option terminators. Low-privileged access that submits credentials for either public or private repository operations is sufficient to exhaust application resources.
