WebDAV Cloud File Desk

• Outcome: Pass
• Latest audit: Oct 26, 2026 · 9:47 PM UTC
• Version: 1.0.1

Overview

This is a coherent, user-directed WebDAV file manager with documented deletion, version checks, and private local state.

Use credentials limited to the intended WebDAV collection and review exact deletion targets: version checks do not confirm intent or guarantee recovery. Protect the profile, credential environment variable and .mochilab state. Pin the installer version if reproducible installation matters.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Output Handling: Unvalidated Output Injection, Cross-Context Output, Unbounded Output
• MCP Least Privilege: Underdeclared Capability, Wildcard Permission, Missing Permission Declaration
• MCP Tool Poisoning: Hidden Instructions, Unicode Deception, Parameter Description Injection

Findings (8)

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 98% confidence

Finding

The delete and mkdir actions expose remote modification capabilities not stated in the description. Deletion is particularly material because it removes remote resources rather than listing, comparing, transferring, or checking them. The ETag requirement provides conflict protection but does not make deletion a declared capability. The remaining visible behavior aligns with the stated purpose.

Content

No source excerpt is available for this finding.

MCP server referenced without pinned version: 'npx clawhub'.

Medium

• Category: MCP Rug Pull
• Confidence: 92% confidence

Finding

The installation command uses npx clawhub@latest, allowing a changing npm release to execute with the installing user's privileges rather than selecting a reviewed version. If the package or its publishing account is compromised, installation could expose workspace files and any accessible WebDAV credentials; however, this README provides no evidence of malicious intent or an actual compromise. The finding incorrectly describes the CLI as an MCP server, but the unpinned execution concern remains valid.

MCP server referenced without pinned version: 'npx clawhub'.

Medium

• Category: MCP Rug Pull
• Confidence: 96% confidence

Finding

The documented command uses npx clawhub@latest, which can download and execute a changing npm package version without review or integrity verification. A compromised or malicious future release could execute code with the installing user's permissions; the WebDAV workflow may make local files and configured credentials valuable targets, although this README does not establish their availability during installation. The finding incorrectly describes ClawHub as an MCP server, but its underlying unpinned-execution concern is valid.

Content

No source excerpt is available for this finding.

Skill declares no tool scope ('permissions' or 'allowed-tools') but code capabilities were detected: env, file_read, file_write, network, shell.

Medium

• Category: MCP Least Privilege
• Confidence: 70% confidence

Finding

Without declared permissions the skill's intent is opaque and cannot be validated.

Content

No source excerpt is available for this finding.

The skill implements remote deletion, which is not disclosed in its manifest description.

Medium

• Category: Excessive Agency
• Confidence: 98% confidence

Finding

The manifest describes listing, comparison, transfers, version checks, and hashing, but the handler also exposes remote deletion. This undisclosed destructive capability could remove remote content using the configured profile's permissions; deletion is plausible in a file-management skill, but its omission prevents users from accurately understanding the skill's scope.

Content

No source excerpt is available for this finding.

Remote file deletion lacks a user warning or confirmation.

Medium

• Category: Output Handling
• Confidence: 88% confidence

Finding

The delete handler sends a WebDAV DELETE request when an ETag is supplied, without a visible warning or explicit confirmation gate. If-Match protects against deleting a changed resource, not against unintended deletion, so an erroneous or manipulated agent request could remove remote content; an independently enforced upstream approval mechanism could mitigate this, but none is shown.

Content

No source excerpt is available for this finding.

The file-writing helper silently replaces existing destination files without documenting the overwrite behavior.

Medium

• Category: Output Handling
• Confidence: 88% confidence

Finding

The atomic() helper writes data and uses os.replace(tmp, p), which replaces an existing destination and loses its previous contents. No confirmation, operation-specific log, docstring, or comment in the supplied file discloses this overwrite behavior.

Content

No source excerpt is available for this finding.

Scope Creep

Low

• Category: Excessive Agency
• Confidence: 70% confidence

Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
