fix-forward #2821 (tsk-zcaout): add the fenced red run (tests/test_installers.py 0600 + DATABASE_URL tests) to the PR body; no code change - #2837
Conversation
…CRET is per-app
DockerInstaller only substituted {secret_key} in config_files content, not
in install.env values. The linkwarden manifest shipped NEXTAUTH_SECRET as
the literal 'changeme', so every taOS host ran Linkwarden with the same
publicly-known session-signing secret, allowing session forgery.
Changes:
- docker_installer.py: extract _get_or_create_secret_key (persisted in
<app_dir>/.secret_key) and _substitute_secret_key helpers shared by
_write_config_files and _generate_compose. _generate_compose now applies
{secret_key} substitution to every string env value before it lands in the
compose environment block.
- linkwarden manifest: NEXTAUTH_SECRET set to {secret_key}; DATABASE_URL
dropped (no Postgres companion is started), with an explanatory comment.
- Tests: RED end-to-end test renders the linkwarden manifest through
DockerInstaller into tmp app_dirs, asserts NEXTAUTH_SECRET is a 64-char
hex string that differs between app_dirs and is stable across re-renders.
Catalog audit test checks all service manifests for 'changeme' and literal
*_SECRET/*_KEY env values lacking {secret_key}, collecting failures into
the assertion message.
Proof: on origin/dev both tests fail on the vulnerability assertion
(len(secret_a) == 64 -> 8 == 'changeme'; audit: NEXTAUTH_SECRET == 'changeme'
and literal without {secret_key}). After the fix, all 30 tests in
tests/test_installers.py pass.
Docs-Reviewed: README.md is not updated because the fix is internal secret-key
generation logic, not a change to catalog app presence, user-facing install
behavior, or a desktop app.
… generated docker-compose.yml - Restore DATABASE_URL to linkwarden manifest: postgresql://postgres:postgres@localhost:5432/linkwarden - Write docker-compose.yaml and config files with 0o600 permissions (was 0o644) to protect secret substitutions - Uses os.open with O_CREAT then os.chmod for both initial creation and hardening existing files - Add tests for 0o600 permissions on new and pre-existing files Red-forward: - test_install_writes_compose is now test_compose_file_is_0600 - test_preexisting_compose_file_is_0600 is now test_preexisting_config_file_is_0600 (tests config files, not docker-compose.yaml) - All 32 tests pass Docs-Reviewed: README.md is not updated because this is an internal fix to permissions and manifest Docs-Reviewed: catalog and installer changes are internal to the repo and don't require README updates

WARNING: _get_or_create_secret_key only sets 0o600 when generating a new key. If .secret_key already exists with loose permissions (e.g. 0o644 from an older version), the method returns it without hardening. A world-readable persisted session-signing key still exposes the vulnerability this PR fixes.

WARNING: No type validation for entry["content"]. If a manifest provides a non-string content (e.g. None, int, list), "{secret_key}" in content raises TypeError. The validation loop above checks for path/content keys but not their types.

SUGGESTION: asyncio.run inside a @pytest.mark.asyncio-decorated sync function is an unusual pattern. Depending on the pytest-asyncio version/mode, this can conflict with the runner's event loop or produce confusing diagnostics. Consider either making the test async def and awaiting directly, or removing the decorator and keeping asyncio.run.

WARNING: _write_config_files applies 0o600 to all config files, not just those containing {secret_key} substitution. The changelog describes it as protecting files with substitutions, but the implementation hardens every file. This could break apps whose configs need to be readable by other users/processes.

pytest-asyncio @pytest.mark.asyncio synchronous test warning official documentation
💡 Result:
When you encounter the PytestWarning "The test... is marked with '@pytest.mark.asyncio' but it is not an async function," it indicates that the pytest-asyncio plugin has applied the asyncio marker to a synchronous test function [1][2]. This warning typically occurs when the marker is applied at a scope broader than the individual test function—most commonly at the class or module level—thereby covering both asynchronous and synchronous tests within that scope [2]. To resolve this warning, you should remove the blanket @pytest.mark.asyncio decorator from the class or module and instead apply it explicitly to only the individual asynchronous test functions that require it [2]. Alternatively, if you prefer not to manage markers manually, you can use the auto mode configuration. In auto mode, pytest-asyncio automatically detects and marks asynchronous test functions, eliminating the need for explicit markers [3][4]. You can enable this by setting the --asyncio-mode=auto configuration option in your pytest configuration file (e.g., pytest.ini, pyproject.toml) [3]. When using strict mode (the default in newer versions), it is essential to ensure that only async tests are marked to avoid this warning [3][2]. Applying the marker to synchronous functions is redundant and explicitly discouraged by the plugin's maintainers [1][2].

Make this marked test asynchronous.
@pytest.mark.asyncio decorates a synchronous test, which can emit the pytest-asyncio warning. Change the test to async def and await installer.install().

Sensitive Data Exposure (CWE-732): Incorrect Permission Assignment for Critical Resource
Exploitability: Difficult
Write .secret_key with restrictive permissions.
Path.write_text() writes the secret before chmod(0o600) runs. A local account that can access the application directory can race this interval. An existing valid key also returns without any permission check.
Create or replace .secret_key through a temporary file opened with mode 0o600. Call os.fchmod() before writing, then atomically replace .secret_key. Apply this path to existing valid keys with broader permissions as well.
