Vulnerability Type: Unsafe dependency resolution and Python module hijacking
Risk Level: Highpython # Import SubAgent system sys.path.insert(0, str(Path(__file__).parent.parent.parent)) from subagent import SubAgentManager, AgentStatusTechnical Analysis
The batch analyzer prepends a broad ancestor directory to
sys.pathbefore importing the externalsubagentmodule. Because index zero has the highest import precedence, Python will load a module namedsubagentfrom that ancestor location before considering normally installed or framework-provided packages.The imported dependency is not included in the audited project and is not pinned to a specific package version or validated source. Python executes module-level code immediately upon import. Consequently, any party able to place a malicious
subagent.pyfile orsubagentpackage in the searched ancestor directory can execute arbitrary Python code whenbatch_product_analyzer.pystarts.This is a dependency-hijacking condition caused by unsafe import-path manipulation. Exploitation requires write access to the selected ancestor directory or another mechanism capable of introducing a module there.
Attack Path
- An attacker identifies the directory inserted into
sys.path, resolved fromPath(__file__).parent.parent.parent. - The attacker obtains write access to that directory, such as through a shared workspace, compromised extraction process, insecure deployment permissions, or another component writing files there.
- The attacker creates a malicious
subagent.pyfile orsubagent/__init__.pypackage in that directory. - A user or OpenClaw process launches
batch_product_analyzer.py. - Python searches the attacker-controlled ancestor directory first and imports the forged module.
- Module-level malicious code executes immediately with the privileges and environment of the proc ...[truncated 775 chars]

Remediation Suggestions
-
Remove the ancestor-directory modification:
python sys.path.insert(0, str(Path(__file__).parent.parent.parent)) -
Import
subagentthrough the OpenClaw framework's supported package or plugin mechanism rather than dynamically expanding Python's search path. -
Declare the dependency explicitly and pin it to an approved version and integrity hash where the deployment system supports hash verification.
-
Package the project as a proper Python module and use explicit package imports. Avoid relying on ambient files outside the project or installed dependency environment.
-
If framework constraints make custom resolution unavoidable:
- Resolve the expected module to a fixed, trusted directory.
- Verify that the resolved path remains within that directory.
- Reject symlinks and unexpected ownership or writable permissions.
- Validate the dependency's cryptographic hash or signature before loading it.
- Avoid adding the location globally to
sys.path.
-
Run the Skill with a least-privileged service account and ensure application, framework, and ancestor directories are not writable by untrusted users or unrelated processes.
-
Add an automated test that inspects
subagent.__file__and fails when the dependency resolves outside the approved OpenClaw installation path.
