RSS Subscription and Reading Hub

• Outcome: Pass
• Latest audit: Oct 26, 2026 · 9:19 PM UTC
• Version: 1.0.1

Overview

The skill matches its feed-reader purpose, with disclosed local storage and reminders scheduled only when requested.

Expect subscriptions, cached articles and notification history to remain locally in .mochilab. Choose a fresh export filename to avoid replacing an existing file. Enable recurring delivery only for your intended schedule and chat. For reproducible installation, pin the installer and resolved dependency versions. The feed workflow does not require WebDAV credentials.

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

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 96% confidence

Finding

The reported authenticated WebDAV enumeration and caller-selected remote write operations exceed the documented RSS reader functionality and introduce an unexpected authority surface. If these operations are reachable with configured credentials, unintended requests could disclose remote collection contents or modify resources within the account's privileges; workspace isolation does not constrain that remote authority. This assessment relies on the static report because the implementation and its authorization checks were not provided.

Content

No source excerpt is available for this finding.

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

Medium

• Category: MCP Rug Pull
• Confidence: 94% confidence

Finding

The installation example uses npx clawhub@latest, which can download and execute a changing package version without a fixed, reviewed release. A compromised future release could execute code with the installing user's permissions, including access to workspace files and available credentials; however, this is an installation CLI, not an MCP server as the finding claims, and the README provides no evidence of malicious intent.

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

Medium

• Category: MCP Rug Pull
• Confidence: 95% confidence

Finding

The documented command uses npx clawhub@latest, allowing a mutable npm release to execute with the installing user's permissions rather than selecting a reviewed version. A compromised or malicious future release could access workspace data or credentials during installation. This is a CLI installation supply-chain risk, not an MCP-server reference as the detector claims; its placement in a legitimate installation guide makes execution plausible but does not establish malicious intent.

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.

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 80% confidence

Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

# Host scheduling and delivery

These scripts keep state and queues; Python by itself does not create a timer. For a user-requested recurring reminder, use the installed OpenClaw scheduler, inspect its current help, and create a job for THIS agent/workspace and the requested chat/account only. Get the timezone, frequency and recipient from the user's request; ask only for missing details. Verify the returned job ID and next run. Never reuse another agent's mailbox credentials or destination.

The job runs poll (email: sync) with the same private profile and workspace. If there are no pending notices, finish quietly. Deliver pending notices through the host's configured messaging tool. After each successful delivery, call ack with only its noticeId. If delivery fails, leave it pending. Maintain the noticeId in the host delivery ledger to avoid duplicate delivery after a retry; this is at-least-once delivery, not a cross-service transaction. Never acknowledge before sending. Manual tests

Atomic file writes can overwrite existing files without disclosure.

Medium

• Category: Output Handling
• Confidence: 86% confidence

Finding

The atomic helper writes to disk and unconditionally replaces the destination with os.replace, potentially discarding existing contents. No confirmation, action-specific log, or explanatory comment or docstring discloses this overwrite behavior in the provided file.

Content

No source excerpt is available for this finding.

The skill implements an authenticated WebDAV collection client, a capability outside the stated RSS reading-hub scope.

Medium

• Category: Excessive Agency
• Confidence: 90% confidence

Finding

L32-L41 enumerate remote WebDAV collection resources using PROPFIND, while L22-L24 expose authenticated requests with caller-selected HTTP methods and bodies. These are general remote-storage capabilities rather than RSS/Atom retrieval or OPML import/export, and the manifest does not declare WebDAV storage or synchronization.

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.

Unverifiable Dependency: feedparser has 10 known advisory(ies) (CVE-2011-1157 (feedparser Cross-site Scripting vulnerability); CVE-2009-5065 (feedparser Cross-site Scripting vulnerability); CVE-2011-1158 (feedparser Cross-site Scripting vulnerability) +7 more), but the manifest does not pin a version, so it is unknown whether the installed release is affected

Low

• Category: Supply Chain
• Confidence: 40% confidence

Finding

OSV returned advisories for this package, but its resolved version is unknown. A package-name lookup does not establish whether the installed release is affected by those advisories.
