Security audit

Pub Agent Browser

Security checks for vulnerabilities and agentic risk

Overview

This skill is a broad third-party API gateway mislabeled as a browser skill and includes email/SMS actions that need careful review before use.

Review this as a broad SkillBoss API integration, not just a browser skill. Only install it if you trust SkillBoss with the data you submit and you are comfortable with agents using the API key for external model calls; require explicit approval before any email, SMS, OTP, scraping, document, audio, or batch messaging action.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Context-Inappropriate Capability

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill is presented as a browser automation skill, but it also documents direct email sending and SMS/OTP workflows. Those capabilities enable external communication and account-verification actions unrelated to browsing, which materially expands abuse potential for spam, phishing, unwanted messaging, or unauthorized verification flows.

Finding

The file exposes broad image, video, TTS, STT, music, document, and search capabilities despite being labeled as an agent-browser skill. This scope mismatch increases the chance an agent or user invokes powerful third-party processing functions without understanding that data will be sent off-platform to unrelated providers.
