X Actionbook Recap

Security checks for vulnerabilities and agentic risk

Overview

This skill provides a disclosed workflow for collecting public X posts, summarizing them, and posting only after confirmation.

Before installing, be aware that this skill is meant to operate through browser automation on X and can help publish posts. Review the target account, final text, and any attached image carefully before approving publication, and treat its language defaults as workflow preferences rather than security concerns.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
Findings (2)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The description says to 'produce Chinese working notes' as part of the workflow, which imposes a specific language requirement. This is a natural-language policy issue because the file does not offer the user a language choice or present the Chinese notes as optional.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The heading explicitly specifies "English, neutral," which is a natural-language locale constraint. Because the file does not offer an opt-in choice of language or explain a region-specific need, it appears to force English output by default, which matches the policy-violation category for language/locale constraints.
