Issuefinder Tool

Security checks for vulnerabilities and agentic risk

Overview

This vehicle-log tool has useful, disclosed log workflows, but it automatically replaces itself with unverified code from a server and keeps executing that home-directory copy later.

Install only if you trust the IssueFinder server and are comfortable sending vehicle logs, VINs, and timestamps to that service. Avoid custom or HTTP servers, use --skip-version-check if running it anyway, and treat archives and downloaded outputs as untrusted until the updater, cached-script override, and path-validation issues are fixed.

Restrict update metadata and payload retrieval to a hardcoded, trusted HTTPS origin. 3. Reject HTTP and other non-HTTPS schemes. 4. Distribute a signed update manifest containing the version and a cryptographic payload hash. 5. Verify the manifest and payload with a pinned public signing key before installation. 6. Download to a securely created temporary file and validate it before atomically replacing any installed version. 7. Require explicit user approval before installing or executing an update. 8. Perform update checks only after argument validation and avoid forwarding sensitive operational arguments to a newly downloaded program. 9. Provide `--skip-version-check` behavior as the default until a verifiable update mechanism exists. ]]>

Persistent Unverified Home-Directory Script Overrides the Packaged Tool<![CDATA[ ## Vulnerability Details **File Location**: `scripts/issuefinder-tool.py`, lines 1285–1297 **Vulnerability Type**: Persistent cached-script execution and tool replacement **Risk Level**: Critical ### Vulnerable Code ```python if __name__ == "__main__": # Check if there's a newer version in ~/.issuefinder/ home_dir = os.path.expanduser("~") updated_tool = os.path.join(home_dir, ".issuefinder", "issuefinder-tool.py") current_script = os.path.abspath(__file__) # If we're not already running from ~/.issuefinder/ and the updated version exists if updated_tool != current_script and os.path.exists(updated_tool): # Check if updated version is newer by comparing file modification time # or if it's different from current script try: # Re-execute with the updated version os.execv(sys.executable, [sys.executable, updated_tool] + sys.argv[1:]) except Exception: pass # If re-execution fails, continue with current version sys.exit(main()) ``` ### Technical Analysis Whenever the packaged tool is invoked, it checks whether `~/.issuefinder/issuefinder-tool.py` exists and executes that file instead. Despite the comments, no version or modification-time comparison is performed. The file is trusted solely because it exists at a predictable user-writable location. Its cryptographic signature, hash, ownership, permissions, provenance, and expected version are not checked. This creates a persistent tool-hijacking path and makes the reviewed package subordinate to unaudited code stored outside the project. This behavior combines with the automatic updater: once a malicious update is written to the home directory, future invocations continue to execute it even if the packaged Skill remains unchanged. ### Attack Path 1. A malicious file is placed at `~/.issuefinder/issuefinder-tool.py`, either through the unsigned updater or another process with access to the user's files. ...[truncated 821 chars]
Remediation
<![CDATA[ ## Remediation Suggestions 1. Remove the automatic preference for `~/.issuefinder/issuefinder-tool.py`. 2. Always execute the packaged, reviewed implementation unless the user explicitly selects another installation. 3. If cached updates are required, verify a cryptographic signature and expected hash before every execution. 4. Validate that the file is a regular file owned by the expected user and is not writable by group or other users. 5. Store trusted updates in a controlled installation location rather than treating an arbitrary home-directory file as authoritative. 6. Record and validate the expected version and provenance; existence alone must never establish trust. 7. Remove any previously downloaded unverified copy from `~/.issuefinder/` during migration. ]]>

Treat both POSIX and Windows path separators and drive prefixes as unsafe when processing remote names. 5. Reject empty names, NUL characters, and special path components. 6.

Context-Inappropriate Capability

High
Confidence
99% confidence
Finding
The self-update mechanism contacts a remote endpoint, downloads a new script, writes it to disk, marks it executable, and immediately replaces the current process with it. This is a high-risk software supply-chain pattern because compromise of the update source or transport yields arbitrary code execution on the client machine, and the skill's stated purpose does not justify this undeclared execution capability.

Missing User Warnings

High
Confidence
98% confidence
Finding
The tool performs automatic self-update and immediate execution without an explicit warning, consent prompt, or integrity verification. Users invoking a log utility would not reasonably expect it to replace itself and run new code on its own, making this a severe trust and code-execution issue.

    except Exception as e:
        if verbose:
Confidence
99% confidence
Finding
The tool downloads replacement Python code from a remote server into ~/.issuefinder and immediately re-executes it with os.execv, with no signature verification, hash pinning, or user confirmation. That creates an arbitrary code execution path controlled by the update endpoint or anyone able to tamper with traffic/server content, which is especially dangerous because this behavior is unrelated to simple log parsing and happens automatically.

Context-Inappropriate Capability

High
Confidence
98% confidence
Finding
The script automatically executes a copy from ~/.issuefinder if it exists, introducing hidden persistence and alternate code loading behavior beyond the advertised functionality. Because the location is user-writable and populated by the self-update path, this creates a durable trust bypass where unreviewed code can take over future executions.

        except Exception:
            pass  # If re-execution fails, continue with current version
Confidence
98% confidence
Finding
On startup, the script checks ~/.issuefinder/issuefinder-tool.py and prefers executing that file instead of the current script. This implicitly trusts previously downloaded code in a user-writable location, enabling persistence and code hijacking if that file is replaced by a malicious local actor or was poisoned by the insecure self-update flow.

Medium
Category
MCP Least Privilege
Confidence
94% confidence
Finding
The skill advertises and instructs use of capabilities including environment variables, file read/write, shell execution, and network access, but it declares no explicit tool scope or permissions boundary. In a skill that downloads remote vehicle logs, extracts archives, updates itself, and writes to user-controlled paths, this omission prevents users and platforms from enforcing least privilege and increases the risk of overbroad access or abuse.

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The natural-language documentation forces a single language presentation throughout the skill file. Under the stated policy, language constraints should either offer user choice or be explicitly documented and justified as region-specific.

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The documentation instructs users to send VINs, timestamps, and vehicle log data to IssueFinder/cloud services, but it does not clearly warn that potentially sensitive telemetry and diagnostic data will be transmitted to remote systems. Because vehicle logs can contain identifiers, operational details, and other sensitive data, users may expose regulated or confidential information without informed consent.

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The documentation explicitly promotes cloud log download and automated analysis of vehicle logs, but provides no warning about the sensitivity of those logs or the privacy/security implications of transmitting them. Vehicle logs can contain VINs, timestamps, device state, crash data, and other sensitive operational information, so normalizing upload/download workflows without disclosure increases the risk of inadvertent data exposure or mishandling.

Natural-Language Policy Violations

Medium
Confidence
94% confidence
Finding
This file contains natural-language documentation and runtime messages in Chinese only, such as the module docstring and later printed status/error text. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale restriction is justified or optional, which is not shown here.

Finding
Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.

Missing User Warnings

Medium
Confidence
87% confidence
Finding
This function reads arbitrary local files and uploads their full contents to a remote server, but the tool does not provide a strong data-transmission warning or consent checkpoint beyond the generic upload mode. In the context of vehicle logs, uploaded data may contain sensitive operational, location, or personal information, so silent or weakly disclosed transmission increases privacy and compliance risk.

Confidence
86% confidence
Finding
Downloaded filenames from the remote environment are joined directly with the local output directory and intermediate directories are created without validating the resulting path. If the server returns names containing ../ or absolute-path elements, the tool can write files outside the intended output directory, enabling overwrite of arbitrary user-accessible files and potentially planting persistent code or configuration.

Confidence
80% confidence
Finding
The code uploads selected local files to a cloud environment, which is core functionality, but it still constitutes off-host data exfiltration from a security perspective. In a vehicle-log context this is somewhat expected, yet still sensitive because archives may contain credentials, proprietary telemetry, or personally identifiable information and the upload is coupled to an external service.

Missing User Warnings

Low
Confidence
80% confidence
Finding
The skill promotes automatic extraction of zip, tar.gz, and 7z archives without warning that extracted contents will be written to disk and may consume space or introduce unsafe filenames/paths. In a log-processing workflow, users may handle untrusted archives, so silent extraction increases the chance of filesystem overwrite, path traversal exposure in downstream tooling, or accidental processing of malicious content.

Natural-Language Policy Violations

Low
Confidence
91% confidence
Finding
A language or locale policy violation applies to all file types when a skill effectively forces a specific language without user opt-in. This file presents all instructions in Chinese and does not indicate that users may choose another language or that the skill is restricted to a Chinese-speaking context.
