Security audit

AnySearch

Security checks for vulnerabilities and agentic risk

Overview

The search functions fit the stated purpose, but setup can execute unverified software and introduce persistent agent changes without clear user control.

Review and install the CLI separately before enabling automatic use. Verify the release and review or disable its automatic skill synchronization. Search inputs pass through OOMOL and AnySearch, and usage may incur charges. The bundled instructions were fully inspected; the remote installers and resulting binaries were not verified.

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

Findings (5)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied code contains no AnySearch interaction. Instead, it executes an external installation script from cli.oomol.com, with no demonstrated connection to the declared AnySearch functionality. This is a material behavioral mismatch, not an established supporting implementation detail. The remote script's contents and resulting system changes are not available for assessment.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
80% confidence
Finding

The supplied chunk performs only a login operation and contains no AnySearch search, reading, or identifiable integration. Authentication could be a supporting implementation detail if connected to AnySearch, but no such connection is established in the supplied code; as presented, its primary behavior differs from the declared purpose.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

Piping a mutable remote installer directly into Bash executes its contents without independent integrity verification or an opportunity for review. A compromised distribution endpoint or malicious installer update could execute arbitrary code with the agent process's permissions; HTTPS and the legitimate setup context do not eliminate this supply-chain risk.

The setup workflow executes downloaded installer scripts without warning about system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

The missing-CLI recovery path directs the agent to execute remotely downloaded shell or PowerShell code without explaining the system changes or requiring explicit installation approval. Although conditional and plausibly legitimate, this turns a search task into host-level code execution with the invoking user's permissions; it overlaps with SC2 rather than representing an independent exploit.

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.
