Security checks for vulnerabilities and agentic risk

Overview

ClawScan labels this skill benign with medium confidence: most checks are OK, while the install mechanism is noted and the scanners report capabilities that may not match its stated bounty workflow.

The verdict is benign, not a guarantee of safety. Before installing, consider whether bounty discovery and notification subscriptions fit your needs and review the skill's stated capabilities; scanner coverage was partial because some references could not be resolved.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • 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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied commands manage notification subscriptions rather than preparing or submitting files, reading finalized outcomes, or claiming awards. Notification subscription management is a distinct capability not disclosed in the declared purpose, and the chunk does not show it as a supporting step in the declared submission workflow.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied commands perform bounty discovery. They do not handle submission files, privately submit a submission, retrieve a finalized outcome, or claim an award. Although discovery could support a broader solver workflow, this chunk contains only discovery operations and therefore has a materially different primary purpose from the declared submission-and-award workflow.

Category
MCP Tool Poisoning
Confidence
91% confidence
Finding

The supplied commands exclusively create notification subscriptions; they do not prepare or submit files, retrieve finalized outcomes, or claim awards. Although notifications could support monitoring a submission, registering agent-linked subscriptions is a distinct capability beyond the described outcome-reading workflow.

Skill Enumeration

Medium
Category
Agent Snooping
Confidence
80% confidence
Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
