Inner Warden Security

Security checks for vulnerabilities and agentic risk

Overview

This skill is coherent for managing Inner Warden, but it needs review because it recommends root-level installation and repair actions, including a mutable GitHub installer run with sudo.

Install only if you are comfortable giving the skill host-administration authority for Inner Warden. Review the installer source and prefer a pinned, signed release or package-manager install before running anything with sudo; also verify exact remediation commands before approving service restarts, ACL changes, config edits, or log compression.

Vulnerability Patterns

Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Tool Hijacking and SpoofingModifies or replaces tools so legitimate-looking calls execute attacker logic
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
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

External Transmission

Medium

Category: Data Exfiltration
Confidence: 95% confidence
Finding: The skill instructs downloading and then executing a remote install script with sudo from GitHub. Even with manual inspection and checksum discussion for later binaries, this pattern creates a high-risk remote code execution path because the script itself is not pinned to a specific version or cryptographically verified before privileged execution.
Content: Scanner excerpt · SKILL.md (reported line 30)May include surrounding context.
To install, first download and inspect the install script:

text
curl -fsSL https://github.com/InnerWarden/innerwarden/releases/latest/download/install.sh -o /tmp/innerwarden-install.sh less /tmp/innerwarden-install.sh

Sudo/Root Execution

Medium

Category: Privilege Escalation
Confidence: 97% confidence
Finding: Running 'sudo bash /tmp/innerwarden-install.sh' executes a downloaded script with full root privileges. If the script source, transport, GitHub account, release pipeline, or local temporary file is compromised, this grants immediate complete system compromise.
Content: Scanner excerpt · SKILL.md (reported line 36)May include surrounding context.
Then run it:

text
sudo bash /tmp/innerwarden-install.sh

The install script downloads binaries from GitHub Releases and verifies each

Intent-Code Divergence

Medium

Category: Not specified by scanner
Confidence: 84% confidence
Finding: The text says the skill 'NEVER transmits credentials off-host' and emphasizes localhost-only API calls, creating a strong impression of strictly local-only operations. Earlier instructions direct use of curl to GitHub to fetch an installer, which contradicts that local-only framing in the documentation even if credentials themselves are not sent.
Content: No source excerpt is available for this finding.

Sudo/Root Execution

Medium

Category: Privilege Escalation
Confidence: 92% confidence
Finding: The ACL remediation uses a placeholder path and grants access with sudo based on a generic 'permission denied' diagnosis. If an agent or user substitutes an attacker-influenced or unsafe path, this can broaden file access to the service account and expose sensitive logs or files beyond the intended scope.
Content: Scanner excerpt · SKILL.md (reported line 158)May include surrounding context.
Fix: permission denied on log files

bash
sudo setfacl -m u:innerwarden:rx /path/to/log/file sudo systemctl restart innerwarden-sensor

Sudo/Root Execution

Medium

Category: Privilege Escalation
Confidence: 90% confidence
Finding: The bulk gzip command performs a recursive privileged modification across application data files older than seven days. Without safeguards, it can alter files currently relied on by the service, affect forensic retention, or follow unsafe assumptions about file types and state, causing data loss or service issues.
Content: Scanner excerpt · SKILL.md (reported line 165)May include surrounding context.
Fix: disk space

bash
sudo du -sh /var/lib/innerwarden/ sudo find /var/lib/innerwarden/ -name "*.jsonl" -mtime +7 -exec gzip {} \;

System status

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 88% confidence
Finding: The trigger condition "check everything" or "health check" is described in natural language without scope limits or negative examples. These phrases are broad enough to match common conversational requests and could cause the skill to run a full diagnostic workflow when the user intended something narrower.
Content: No source excerpt is available for this finding.

Context-Inappropriate Capability

Low

Category: Not specified by scanner
Confidence: 77% confidence
Finding: The manifest describes a security partner that validates commands, monitors server health, and diagnoses or fixes issues in Inner Warden. Reading /etc/innerwarden/agent.env to extract INNERWARDEN_DASHBOARD_USER is not obviously necessary for those core functions, especially since the file contains authentication-related configuration and the skill already notes most functionality works without API auth.
Content: No source excerpt is available for this finding.
