What is CVE-2026-110867?

An allowlist bypass vulnerability exists in Renovate versions prior to 44.60.1, allowing attackers to manipulate environment variables. By utilizing a shared preset sourced externally, malicious actors can override critical variables such as PATH, LD_PRELOAD, NODE_OPTIONS, and GIT_SSL_CAINFO in child processes on self-hosted instances. This enables unauthorized access and potential exploitation of the system's environment settings.
