Important Dates and Holidays

Security checks for vulnerabilities and agentic risk

Overview

The skill’s local date tracking, calendar exports, and user-requested reminders fit its stated purpose, with routine installation and file-overwrite cautions.

Keep the .mochilab data private. Verify reminder recipients, time zones, and schedules, and disable scheduled jobs when no longer needed. Choose a fresh export filename to avoid replacing an existing file. Use reviewed installer and dependency versions in the documented virtual environment.

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

Findings (9)

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

Medium
Category
MCP Rug Pull
Confidence
92% confidence
Finding

The recommended command uses npx clawhub@latest, which downloads and executes a mutable package version rather than an explicitly reviewed release. A compromised or malicious future release could execute with the installing user's permissions and access workspace data or available credentials. This is an optional installation-time supply-chain risk, not evidence of malicious behavior; the finding's description of ClawHub as an MCP server is unsupported by this README.

MCP Rug Pull
Confidence
96% confidence
Finding

The installation command uses npx clawhub@latest, which downloads and executes a mutable package version rather than a reviewed, pinned release. A compromised future release could execute code with the installing user's permissions and access workspace data or available credentials. Although the static finding incorrectly describes this CLI as an MCP server, the underlying dependency-pinning risk is real; this is an optional installation instruction, not evidence of malicious behavior.

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, 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

File-writing helper silently replaces existing destination files without disclosing the overwrite.

Medium
Category
Output Handling
Confidence
86% confidence
Finding

The atomic helper writes data and calls os.replace(tmp, p), which replaces an existing destination file. Neither this helper nor its writejson wrapper provides a confirmation, action-specific log, or docstring/comment explaining that existing contents will be overwritten.

Content

Credential-environment access is unrelated to the declared important-dates functionality.

Medium
Category
Excessive Agency
Confidence
95% confidence
Finding

The secret() helper reads a configuration-selected environment variable and returns its value, explicitly treating it as a credential. Tracking dates, generating advance alerts, and exporting calendars do not inherently require credential retrieval, and the manifest declares no authenticated service integration. This file implements the capability but does not show it being invoked.

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: icalendar has 2 known advisory(ies) (CVE-2026-55099 (icalendar has Algorithmic Complexity in Equality); CVE-2026-55099 (icalendar has Algorithmic Complexity in Equality)), 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.

Unpinned Dependencies

Low
Category
Supply Chain
Confidence
50% confidence
Finding

Dependencies lack version pinning, allowing potential malicious package updates. Consider pinning versions.
