SKILL.md, lines 213–215
Vulnerability Type: Plaintext credential exposure through process arguments
Risk Level: MediumVulnerable Code:
bash skill configure --enable-canonical-auto-inject \ --wordpress-api-key="your-token" \ --verify-with-gscTechnical Analysis
The documented command instructs users to replace
your-tokenwith a WordPress API credential and pass it directly as a command-line argument. Command-line secrets can be exposed through shell history, process inspection utilities, command auditing, CI/CD logs, terminal capture, telemetry, and diagnostic output.Although the repository contains only documentation and no executable implementation, following this configuration example with a real credential would create a concrete secret-disclosure risk. The available access would depend on the permissions assigned to the exposed WordPress token.
Attack Path
- A user replaces
your-tokenwith a valid WordPress API token. - The user executes the documented command.
- The complete command and token are retained in shell history, captured in logs, or temporarily exposed through the operating system's process metadata.
- A local user, administrator, CI/CD log reader, monitoring service, or other party with access to those records obtains the token.
- The party authenticates to the associated WordPress API using the exposed credential.
- The party performs operations allowed by the token, potentially including unauthorized content or canonical-tag modification.
Impact Assessment
Successful exploitation exposes the privileges granted to the WordPress API token. Depending on its scope and associated account, an attacker could read protected site data, modify published content, alter canonical tags and SEO metadata, or perform other WordPress API operations. The impact is limited by the token's configured permissions but could affe ...[truncated 63 chars]

Remediation Suggestions
- Do not accept API credentials directly through command-line arguments.
- Retrieve the token from a protected environment variable, operating-system credential store, or dedicated secrets manager.
- Alternatively, request the token through an interactive prompt that disables terminal echo.
- Ensure application logs and diagnostic output redact credentials.
- Configure restrictive permissions for shell-history and CI/CD log files, and disable history recording for commands that may contain secrets.
- Issue a dedicated, least-privilege WordPress token limited to the operations required for canonical-tag management.
- Document credential rotation and immediate revocation procedures for potentially exposed tokens.
- Prefer a configuration pattern such as:
bash export WORDPRESS_API_TOKEN="..." skill configure --enable-canonical-auto-inject \ --wordpress-api-token-env="WORDPRESS_API_TOKEN" \ --verify-with-gsc
