Disclosure: I used an LLM to help organize and edit this description. The investigation, ideas, and technical conclusions are my own.

Closes SEM-210.

This PR also supersedes #3865 (fix(db): SQL CreateTemplate must return persisted vault IDs). The template persistence changes include the same hydration-order fix—assigning the generated template ID before calling FillTemplate—and add regression coverage confirming that CreateTemplate returns persisted vault IDs.

Summary

Adds an optional repository-relative working directory for Ansible templates.

When configured, Semaphore runs ansible-playbook and related Ansible commands from that directory. Templates without a working directory continue to run from the repository root.

The validation also closes a mixed-separator repository escape for working-directory values such as x\y\z/../../external.sh. On POSIX, x\y\z is one valid directory name rather than three path components, so the two .. components would escape the repository root even though the Windows interpretation remains contained. Semaphore now validates both interpretations independently and rejects the path if either can escape.

Changes

  • Add an Ansible-only Working directory field to the template form.
  • Expose working_directory through the template API.
  • Persist the nullable field through migration v2.20.2.
  • Return it from template create, read, list, and update operations.
  • Validate paths lexically and independently under both POSIX and Windows path semantics:
    • reject absolute paths;
    • reject paths escaping the repository, including mixed-separator paths whose interpretation differs by platform;
    • reject empty or whitespace-only values;
    • reject working directories on non-Ansible templates.
  • Recheck containment using runner-native path semantics before execution.
  • Set the Ansible process directory to the configured repository subdirectory.
  • Keep playbook and file-inventory paths relative to their repository roots by resolving them to absolute paths before invoking Ansible.
  • Document the field in the API specification.

Validation is lexical only. Semaphore does not require the directory to exist during template validation and does not resolve symlinks.

Behavior

Given:

Repository root:   /tmp/project
Working directory: ansible/deploy
Playbook:          playbooks/site.yml
Inventory:         inventories/prod.ini
Arguments:         --extra-vars @vars.yml

Semaphore runs Ansible with:

Process directory: /tmp/project/ansible/deploy
Playbook:          /tmp/project/playbooks/site.yml
Inventory:         /tmp/project/inventories/prod.ini
Extra-vars file:   resolved by Ansible from the working directory

This enables working-directory-based discovery of:

  • ansible.cfg
  • roles and collections configured through ansible.cfg
  • relative extra-vars files
  • relative private-key paths
  • other relative Ansible CLI arguments

Compatibility

  • Existing templates are unchanged because working_directory defaults to null.
  • Playbook paths remain repository-relative.
  • File inventories remain relative to their template or inventory repository.
  • The feature is available only for Ansible templates.

Testing

Added coverage for:

  • POSIX and Windows lexical path validation
  • Ansible-only field validation
  • database create/read/list/update/clear round trips
  • default repository-root execution
  • configured working-directory resolution
  • repository escape rejection
  • repository-rooted playbook and inventory arguments
  • persisted vault IDs during template creation

End-to-end integration coverage verifies:

  1. ansible.cfg discovery and role loading
  2. relative --extra-vars @vars.yml resolution
  3. relative --private-key key.pem resolution

Summary by CodeRabbit

  • New Features

    • Ansible templates can now specify a repository-relative working directory.
    • Added an optional working-directory setting to the template form, with validation.
    • Ansible commands now run from the configured directory while remaining within the repository.
    • Template APIs support reading and updating the working-directory setting.
  • Bug Fixes

    • Improved playbook and inventory path resolution using repository-rooted paths.
    • Added validation to reject absolute paths and paths outside the repository.

- persist and validate repository-relative working directories
- expose the option only for Ansible templates
- refactor template writes with Squirrel
- return persisted vault associations after creation
Pass the configured directory to the Ansible runner and use it as the
command working directory while preserving the repository-root default.
Enforce lexical repository containment, document the API field, and add
persistence and path-resolution tests.
Resolve playbook and inventory file paths before invoking
ansible-playbook so a configured working directory does not change which
files are used.

Extract dedicated path-resolution helpers and add coverage for
repository-rooted command arguments.

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds nullable, repository-relative working directories for Ansible templates. It validates and stores the value, applies it to Ansible commands, resolves task paths from the repository root, and adds form controls and API documentation.

Changes

Working directory support

Layer / File(s) Summary
Template contract, validation, and persistence
api-docs.yml, db/Template.go, db/working_directory_path.go, db/sql/..., db/Migration.go, db/Inventory.go
Template definitions and storage now support working_directory. Validation rejects unsupported, empty, absolute, or repository-escaping paths.
Ansible command working directory
db_lib/AnsiblePlaybook.go, db_lib/AppFactory.go, db_lib/AnsiblePlaybook_test.go
Ansible commands resolve the working directory below the repository root and propagate resolution errors.
Repository-rooted task paths
services/tasks/local_executor.go, services/tasks/local_executor_test.go, services/tasks/TaskRunner_test.go
Playbook and inventory paths now use repository-rooted paths, and inventory arguments use --inventory.
Template form controls
web/src/components/TemplateForm.vue, web/src/lang/en.js
Ansible templates now have a working-directory toggle and required field with localized text.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 86b52

The new working-directory setting can cause Ansible to run from outside the repository when a repository path is a symlink, potentially exposing deployment credentials and inputs to an unintended location. Related template updates can also fail after the execution directory has already been saved, leaving runtime behavior changed despite an error response; these issues should be addressed before merging.

Security review

Outcome: No medium, high, or critical vulnerabilities identified in the added/modified code.

Scope reviewed: working_directory template field (API, DB, Ansible runner), playbook/inventory path resolution changes, and related validation.

Prior threads: No previous automation security-review threads were found on this PR.

Areas checked

Area Assessment
Path traversal (working_directory) MitigatedValidateWorkingDirectoryLexically() at save time plus filepath.Rel + filepath.IsLocal at execution time (db/working_directory_path.go, db_lib/AnsiblePlaybook.resolveWorkingDirectory)
Playbook/inventory path handling Improved — playbook and file inventory paths are now rooted under the repository via filepath.Join, which is safer when a custom working directory changes process CWD
Authz OK — template create/update requires CanManageProjectResources (api/router.go)
SQL injection (squirrel refactor) OK — parameterized inserts/updates
Command injection OK — paths passed as exec.Command argv elements, not shell-joined
XSS (TemplateForm) OK — standard v-text-field binding

Notes (below reporting threshold)

Lexical validation intentionally does not resolve symlinks; a repo-contained symlink could make the effective process CWD differ from the composed path. This requires template-management permission and control of repo contents, and is consistent with existing playbook execution trust boundaries.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject whitespace-only working directories in the form.

Line 280 treats " " as valid because whitespace is truthy. The backend rejects whitespace-only paths, so the form can pass validation and then fail during save. Use a trimmed non-empty check.

Proposed fix

+              :rules="[
