Bug Report: [security] — Review for hardcoded secrets in src/cleveragents/services

Severity Assessment

  • Impact: Hardcoded secrets could lead to unauthorized access to external services.
  • Likelihood: Unknown without code access.
  • Priority: High

Location

  • File: All files in src/cleveragents/services
  • Function/Class: N/A
  • Lines: N/A

Description

A manual review of the src/cleveragents/services module is required to ensure that no hardcoded secrets (e.g., API keys, passwords) are present in the code.

Per the project's architectural design:

  • The Config Service is responsible for multi-level configuration resolution, meaning service modules may interact with configuration values that could inadvertently contain hardcoded credentials.
  • The architecture integrates with external LLM providers, MCP tool servers, and A2A agents, all of which require authentication tokens or API keys that must be sourced from environment variables or a secure vault — never hardcoded.
  • The Service Layer Pattern encapsulates business logic and external integrations, making it a likely location for credential usage that must be audited.

Evidence

N/A (code not accessible at time of filing)

Expected Behavior

The code should not contain any hardcoded secrets. Secrets should be loaded from environment variables or a secure vault (e.g., via os.environ, a secrets manager, or the Config Service's secure resolution chain).

Actual Behavior

Unknown without code access. Compliance with secrets management standards has not been verified for this module.

Suggested Fix

Manually review all files in src/cleveragents/services and:

  1. Search for any string literals that resemble API keys, passwords, tokens, or other credentials.
  2. Verify that all secrets are loaded from environment variables or a secure configuration source.
  3. Replace any hardcoded secrets with environment variable lookups or Config Service calls.
  4. Add or update documentation to clarify the expected secrets management approach for this module.

Metadata

  • Branch: fix/security-hardcoded-secrets-services
  • Commit Message: fix(services): remove hardcoded secrets and enforce secure credential loading in services module
  • Milestone: v3.7.0 (TUI)
  • Parent Epic: #400

Subtasks

  • Audit all files in src/cleveragents/services for string literals resembling API keys, passwords, tokens, or other credentials
  • Identify any direct use of hardcoded secrets passed to external service clients (LLM providers, MCP servers, A2A agents, etc.)
  • Verify that all credential values are sourced from environment variables or the Config Service's secure resolution chain
  • Replace any hardcoded secrets with os.environ lookups or Config Service calls
  • Ensure no secrets are logged, printed, or otherwise exposed in error messages or debug output
  • Review test fixtures and mocks in features/mocks/ to ensure test credentials are clearly synthetic and not real secrets
  • Tests (Behave): Add/update scenarios verifying that services raise appropriate errors when required secrets are missing from the environment
  • Tests (Behave): Add/update scenarios verifying that services correctly load credentials from environment variables
  • Verify coverage >= 97% via nox -s coverage_report
  • Run nox (all default sessions), fix any errors

Definition of Done

This issue is complete when:

  • All subtasks above are completed and checked off.
  • No hardcoded secrets (API keys, passwords, tokens, or other credentials) exist anywhere in src/cleveragents/services.
  • All secrets are loaded from environment variables or the Config Service's secure resolution chain.
  • No secrets are exposed in logs, error messages, or debug output.
  • A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly, followed by a blank line, then additional lines providing relevant details about the implementation.
  • The commit is pushed to the remote on the branch matching the Branch in Metadata exactly.
  • The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.
  • All nox stages pass
  • Coverage >= 97%

MoSCoW classification: MoSCoW/Must Have

Priority classification: Priority/High

Rationale: A security audit for hardcoded secrets in the services module is essential. The specification defines the Service Layer as the integration point for external LLM providers, MCP tool servers, and A2A agents — all of which require authentication tokens. Hardcoded secrets in this module would be a critical security vulnerability. Per the spec, all credentials must be sourced from environment variables or the Config Service's secure resolution chain. This audit is a Must Have for any release.

Label compliance fix applied:

  • Removed conflicting label: Priority/Medium (repo-level duplicate)
  • Kept: Priority/High (org-level canonical label)
  • Reason: Issue had two conflicting Priority/* labels. Per CONTRIBUTING.md, each issue must have exactly one Priority/* label. Priority/High is consistent with the MoSCoW/Must have classification for a security review.
