compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From version 0.30.0 until 0.32.0, the compose-lint GitHub Action prints the resolved directory from a failed sarif-file subdirectory creation without effective command suppression. Version 0.30.0 has no stop-commands window, while version 0.31.0 prints this error outside its stop-commands window. A pull request can place a committed symlink on that path to a directory whose name contains a newline followed by a workflow command, causing the SARIF-directory error to issue commands in the job log. Only the Action with sarif-file pointing into a subdirectory is affected; a workspace-root SARIF file, the compose-lint package, the pre-commit hook, and the Docker image do not expose this message. This issue is fixed in version 0.32.0.

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. In version 0.31.0, compose-lint does not neutralize the Azure Pipelines ##vso[ logging-command opener on any output path. A pull request can place that opener in a Compose value or file name, allowing output from the package, pre-commit hook, or Docker image to issue logging commands when printed to an Azure Pipelines job log. The maintainer did not reproduce the behavior on an Azure Pipelines agent. The GitHub Action is not affected because it runs only on GitHub Actions, and releases before 0.31.0 are outside this advisory because they did not claim Azure Pipelines coverage. This issue is fixed in version 0.32.0.

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. In version 0.31.0, compose-lint's argument parser writes rejected repository paths to stderr without the output sanitizer when a path is passed without a preceding -- separator. A pull request can supply a path containing workflow-command syntax; a carriage return can position that command at the start of a new line recognized by the GitHub Actions runner, allowing the package, Docker image, or a pre-commit hook with misconfigured args to issue the command in the job log. The default pre-commit configuration includes -- and is not affected, the GitHub Action is not affected, and the lint pass or fail result is unchanged. This issue is fixed in version 0.32.0.

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. In version 0.31.0, compose-lint does not sanitize the ##[ workflow-command opener inside strings written by --format json or --format sarif to stdout. A pull request can place that opener in a service name or other Compose value, and the GitHub Actions runner recognizes it even in the middle of a serialized line when the package, pre-commit hook, or Docker image prints JSON or SARIF to the job log. Writing the output to a file and using the compose-lint GitHub Action are not affected, and the flaw does not change the lint pass or fail result. This issue is fixed in version 0.32.0.

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. In version 0.31.0, compose-lint escapes GitHub Actions workflow-command openers only after ASCII spaces and tabs, while the runner strips all leading Unicode whitespace before interpreting a line. Untrusted Compose values or repository paths beginning with Unicode whitespace followed by :: can therefore reach the text report, fix guidance, the fix dry-run diff, and stderr diagnostics as workflow commands when the package, pre-commit hook, or Docker image runs directly in CI. The GitHub Action is not affected because it disables command processing, and the flaw does not change the lint pass or fail result. This issue is fixed in version 0.32.0.

Nov 9, 2026compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment.CVE-2026-123796 · Other software · tmatens · reported by GitHubLow 2.3
compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.32.0 until 0.33.0, compose-lint's incomplete remediation for .env secret disclosure checks the 20,000-finding limit before replacing resolved values with their variable references. A pull request can combine a secret-referencing image field with aliased content that produces more than 20,000 findings, causing the early-stop path to emit already graded findings with the resolved secret value in text, JSON, SARIF, and Code Scanning output. Exploitation requires a workflow that writes secrets into the sibling .env and lints untrusted changes, and the run exits 2 unless --allow-partial-coverage is used. This issue is fixed in version 0.33.0.

Nov 9, 2026compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment.CVE-2026-123373 · Other software · tmatens · reported by GitHubLow 2.3
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.

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.22.0 until 0.32.0, compose-lint substitutes values from a sibling .env file into image fields and quotes the resolved value in CL-0004 and CL-0019 finding messages and fix text. In a workflow that writes secrets into that file and then lints untrusted pull-request content, an attacker can reference a secret variable so its whole value reaches the job log, JSON output, SARIF artifacts, and Code Scanning alerts. Fork pull requests normally lack secrets, so exploitation requires a secret-bearing workflow such as pull_request_target, same-repository branches, or a retained .env on a self-hosted runner, and the pass or fail result is unchanged. This issue is fixed in version 0.32.0.

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.2.0 until 0.32.0, compose-lint automatically follows a .compose-lint.yml policy-file symbolic link outside the project and includes part of the target line when that external file fails YAML parsing. A pull request can point the policy file at a runner credential file, causing about 30 characters around an attacker-uncontrolled parse position to appear in standard error, JSON errors, and SARIF tool execution notifications uploaded by the GitHub Action. The run exits with an error and the attacker cannot select the exact disclosed line, but public logs or Code Scanning output can reveal part of the target. This issue is fixed in version 0.32.0.

Nov 9, 2026compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment.CVE-2026-123370 · Other software · tmatens · reported by GitHubMedium 5.1
compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.9.0 until 0.18.0, compose-lint's YAML parser recognizes lone carriage returns and Unicode line separators U+0085, U+2028, and U+2029 as line breaks while fix position conversion counts only newline characters. A pull request can place one of these separators in a quoted value so fix --apply shifts each later edit and deletes the line after the selected target, including an unselected network or other security setting. The resulting Compose file can remain valid, post-edit checks can pass, and the command can report a successful fix even though the dry-run diff was the only place showing the extra deletion. This issue is fixed in version 0.18.0.

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. Prior to 0.31.0, compose-lint prints attacker-controlled service names, environment keys, file lines, and other Compose text without neutralizing GitHub Actions and Azure Pipelines workflow-command openers. When a workflow processes a pull request, legacy ##[ commands or a line-leading double-colon command can create false annotations, hide log regions, mask selected strings, or invoke other commands recognized by the runner. The affected text report paths do not alter the compose-lint exit code or pass or fail result, but they can misrepresent the CI output presented to reviewers. This issue is fixed in version 0.31.0.

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.22.0 until 0.31.0, compose-lint follows a sibling .env symbolic link outside the project without applying its normal containment check. From 0.28.0, the same gap also affects an include project_directory link outside the project. A pull request can reference a variable from the linked file, causing substitution to place runner file or process-environment data into finding messages written to logs, JSON, SARIF artifacts, and Code Scanning alerts. Reading /proc/self/environ can expose the remainder of the linter process environment because NUL-separated entries are treated as one value, although disclosure requires a workflow that processes untrusted changes with useful environment data and GitHub normally withholds secrets from fork pull requests. The pass or fail result is not changed. This issue is fixed in version 0.31.0.
