CVE-2026-123373

2.3 LOW Fix listed Other Library

What it is

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.2.0 until 0.25.0, compose-lint follows a project-controlled symbolic link used as the Compose file outside the project. The same issue affects compose.override.yml and a COMPOSE_FILE entry from 0.22.0, and an env_file target from 0.23.0. If an external Compose-related target fails YAML parsing, the error quotes an attacker-uncontrolled line into standard error, JSON errors, and SARIF notifications, while an external env_file can expose credential-like key names through CL-0020 and CL-0021 findings. The attacker selects the target path but not the exact parser-failure line, values from env_file are not printed, and the pass or fail result is unchanged. This issue is fixed in version 0.25.0.
