Pane Skill

Security checks for vulnerabilities and agentic risk

Overview

This Pane integration is mostly disclosed, but its delayed cron follow-ups can keep acting later in a workspace session without fresh approval.

Install only if you want an agent to use your paired Pane Gateway token to create, edit, and inspect Pane workspace content. Confirm PANE_GATEWAY_URL points to your trusted local gateway, protect PANE_GATEWAY_TOKEN, avoid insecure TLS outside development, and be aware that the skill may schedule one-shot follow-up actions for multi-step Pane session work.

Vulnerability Patterns
  • 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
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Tool Parameter Abuse

Tool Misuse
Confidence
60% confidence
Finding

Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Description-Behavior Mismatch

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill description says it can create notes, tasks, and projects, but the API reference explicitly states the corresponding resource endpoints do not exist and that such operations must instead be routed through conversational session flow. This mismatch can cause agents to improvise by sending free-form instructions to an LLM-backed session to perform actions indirectly, reducing determinism, auditability, and policy control over what operations are actually executed.

## Unreachable/blocked-in-v1 endpoints

These do **not** exist on the gateway and should never be constructed:
`POST/GET/PUT/DELETE /v1/notes*`, `/v1/tasks*`, `/v1/projects*`,
`/v1/folders*`. Requests to any of these hit the router's fallback handler
(404). Use the conversational session flow in `SKILL.md` instead.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
85% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

text

**2. Skip verification (dev only).** If `PANE_GATEWAY_INSECURE_TLS=1` is set,
use `-k`/`--insecure`. Do not default to this silently — only use it when the
env var is explicitly set, and mention to the user that verification is
skipped.

External Transmission

Medium
Category
Data Exfiltration
Confidence
79% confidence
Finding

This sends arbitrary user-supplied content into a privileged Pane session where Pane's in-app AI may invoke internal tools such as creating or editing notes, tasks, or projects. Because the skill explicitly relies on natural-language interpretation by another agent-like component, prompt injection or ambiguous instructions can cause unintended state-changing actions inside the user's workspace.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The skill expands its scope from operating a local Pane gateway to scheduling future autonomous actions via openclaw cron add. That creates persistence and delayed execution beyond the user's immediate request, which can be abused to continue acting in the same session without fresh confirmation and increases the blast radius if prompts are ambiguous or malicious.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The documented POST /v1/chat/completions capability is broader than the skill metadata suggests, enabling arbitrary stateless LLM interactions outside the Pane session/history model. This expands the effective authority of the skill and can mislead users or higher-level policy into granting a tool more capability than advertised, which is a scope/intent mismatch with security implications.

Description-Behavior Mismatch

Low
Category
Not specified by scanner
Confidence
82% confidence
Finding

The manifest centers the skill on creating/managing Pane content via chat sessions and managing AI sessions. The direct POST /v1/chat/completions proxy is a more general-purpose LLM completion capability outside Pane sessions, which goes beyond the stated session-oriented Pane operation scope.
