Bug Bounty Report Template

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward bug bounty report template generator with disclosed, user-directed file output and no evidence of hidden or harmful behavior.

Before installing, understand that the skill runs a local Python script and may overwrite a file if you pass an existing path with --output. It does not appear to access credentials, contact the network, install dependencies, or persist changes beyond the report file you ask it to create.

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
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

MCP Least Privilege
Confidence
89% confidence
Finding
The skill invokes a local script and explicitly supports writing output to a file via the `--output FILE` option, but the manifest does not declare any tool scope such as `permissions` or `allowed-tools`. This creates an authorization gap where a consumer may not have clear, enforceable limits on file-writing behavior, increasing the risk of unintended file modification or data clobbering if the skill is run in a broader agent environment.

Excessive Permissions

Low
Category
Privilege Escalation
Content
An attacker can:
- [Impact 1 — e.g., Access other users' private data]
- [Impact 2 — e.g., Perform actions on behalf of other users]
- [Impact 3 — e.g., Escalate privileges to admin]

## Remediation
Confidence
80% confidence
Finding
Skill requests more permissions than appear necessary for its stated functionality. Review if elevated access is justified.
