Log Analyzer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward log analysis guide, but users should handle logs as sensitive data and pin example dependencies in real projects.

Install is reasonable for log debugging workflows. Use it only on logs you are authorized to inspect, avoid printing or sharing sensitive fields, redact personal data and secrets before exporting results, and pin dependency versions when adapting the structured logging examples.

A.I.G

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

Vulnerability Details

File Location: SKILL.md:266
Vulnerability Type: Unpinned third-party dependency
Risk Level: Medium

Vulnerable Code

javascript
// npm install pino

Technical Analysis

The Skill recommends installing pino without specifying an exact version, lockfile, integrity hash, or trusted registry. Consequently, the package resolved at installation time can differ from the version originally reviewed.

This creates supply-chain exposure if the package, one of its transitive dependencies, or the configured npm registry is compromised. npm installation can execute package lifecycle scripts, so malicious package content may run before the dependency is used by the example application.

Attack Path

  1. An attacker compromises a future package release, a transitive dependency, or the package source used by the environment.
  2. A user or Agent follows the instruction and runs npm install pino.
  3. npm resolves the current unpinned dependency graph rather than a previously reviewed version.
  4. Malicious lifecycle code executes during installation, or malicious library code executes when the application imports and uses the package.
  5. The payload operates with the privileges and environmental access of the process performing the installation or running the application.

Impact Assessment

Successful exploitation could permit arbitrary code execution under the installing user's account. The resulting access may include readable source code, log files, environment variables, application credentials, and files writable by that account. The Skill does not request elevated privileges, so the direct impact is normally limited to the privileges of the user or Agent executing the command.

Remediation

Remediation Suggestions

  • Specify an exact, reviewed package version rather than installing the latest release implicitly.
  • Commit and enforce a lockfile containing dependency versions and npm integrity metadata.
  • Use npm ci for reproducible installation from the reviewed lockfile.
  • Configure an approved registry and prevent unexpected registry overrides.
  • Review transitive dependencies and package lifecycle scripts before installation.
  • Run dependency installation in a restricted, non-privileged environment without production credentials.
  • Add automated supply-chain scanning and update dependencies through reviewed change requests.

Unpinned Python Dependency Installation

Vulnerability Details

File Location: SKILL.md:289
Vulnerability Type: Unpinned third-party dependency
Risk Level: Medium

Vulnerable Code

python
# pip install structlog

Technical Analysis

The Skill recommends installing structlog without an exact version, hash verification, constraints file, or explicit trusted package index. This causes pip to resolve whichever compatible package and transitive dependencies are available at installation time.

If a package release, transitive dependency, configured index, or package-distribution account is compromised, installation or subsequent import may expose the environment to attacker-controlled code. The absence of hashes also prevents pip from verifying that downloaded artifacts match artifacts approved during review.

Attack Path

  1. An attacker compromises a package release, a transitive dependency, or the Python package index configured in the target environment.
  2. A user or Agent follows the instruction and runs pip install structlog.
  3. pip resolves an unpinned dependency graph and downloads artifacts that were not fixed during the Skill review.
  4. Attacker-controlled build or package code executes during installation or when the package is imported.
  5. The payload gains the permissions and accessible environment of the Python installation or application process.

Impact Assessment

Successful exploitation could result in arbitrary code execution with the installing user's privileges. Accessible assets may include application files, logs, environment variables, tokens, and other data readable or writable by that account. No privilege-escalation instruction is present, so the direct scope is limited to the permissions already held by the invoking process.

Remediation

Remediation Suggestions

  • Pin structlog and every transitive dependency to reviewed versions.
  • Use a requirements or constraints file generated with cryptographic hashes.
  • Install with hash enforcement, such as pip install --require-hashes -r requirements.txt.
  • Explicitly configure an approved package index and disable unintended extra indexes.
  • Prefer pre-reviewed wheels and avoid untrusted source builds.
  • Perform installation in an isolated virtual environment or restricted container without production secrets.
  • Scan dependencies continuously and apply updates only after security review.

Missing User Warnings

Confidence
92% confidence
Finding

This markdown file includes concrete commands that extract and display sensitive fields from logs, such as .context.userId and message contents, but it does not warn users that logs may contain personal data, identifiers, or secrets. Because SQP-2 applies to markdown files when descriptions omit warnings about behaviors affecting privacy, this is a user-disclosure gap.

Missing User Warnings

Finding

The examples explicitly log fields like userId, user_id, and ip, which can affect user privacy and data handling obligations. The markdown does not include any caution about minimizing sensitive fields in logs or obtaining appropriate authorization for such logging.
