Security audit

AnyDB

Security checks for vulnerabilities and agentic risk

Overview

The AnyDB workflow has clear approval controls, but its setup fallback executes remote installers without verification or explicit user approval.

Review and approve the CLI installation separately before using this skill, including any bundled agent-skill changes. Prefer a pinned, verified installer and a narrowly scoped AnyDB connection. The remote installer's exact effects remain unverified; no malicious behavior was established in the bundled artifact.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied code performs remote script execution associated with Oomol rather than any visible AnyDB operation. Nothing in the supplied chunk establishes this installer as a supporting dependency for AnyDB. The downloaded script's contents and downstream effects are not available for assessment.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a mutable remote script directly into bash executes its contents without a prior integrity check or review; the PowerShell alternative has the same weakness. Compromise of the distribution endpoint or release process could execute attacker-controlled code with the invoking user's privileges, although this path is conditional on missing software and may be blocked by enforced tool restrictions.

The setup workflow executes downloaded installation scripts without warning about the system-level effects.

Medium
Category
Output Handling
Confidence
92% confidence
Finding

The missing-CLI fallback directs the agent to install software without explaining the local changes or requiring explicit installation approval. An AnyDB data request does not necessarily authorize executing an installer with the agent's local privileges, although the conditional setup path and declared Bash(oo *) restriction reduce exposure if that restriction is enforced.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
