ClawBrain Recall

Security checks for vulnerabilities and agentic risk

Overview

This is a simple recall skill that clearly describes searching past conversations, with no bundled code or hidden install behavior.

Install this only if you are comfortable with the agent searching prior conversation memory when you ask recall-style questions. Review the Chinese documentation first and disable or avoid the skill if automatic memory lookup would be unwelcome.

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
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The manifest description and all user-facing instructions are presented only in Chinese, with no indication that language is configurable or limited to a Chinese-speaking context. This can violate a language/locale policy when the skill implicitly assumes a single language without user opt-in.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The listed trigger phrases are common conversational expressions that users may naturally say outside an intent to invoke the skill. This can cause unintended automatic activation, leading to unnecessary access to historical conversation data and surprising retrieval of prior context the user did not explicitly request through a clear command boundary.
