Renovate before 44.60.1 contains an allowlist bypass vulnerability that allows repositories to set restricted environment variables by placing env inside a shared preset. Attackers controlling an externally sourced preset can override variables like PATH, LD_PRELOAD, NODE_OPTIONS, or GIT_SSL_CAINFO in child processes on self-hosted instances.
