Security audit

Lingvanex Translation API

Security checks for vulnerabilities and agentic risk

Overview

The translation workflow is appropriate, but setup executes unverified remote code and can add other agent skills without explaining those changes.

Review and verify the CLI installation before allowing automatic setup. Its installer contents remain unverified. If additional agent skills are unwanted, the publisher documents OO_SKILLS_SYNC_DISABLED=1 to prevent startup skill writes; configure it before running oo. [CLI controls](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md) Submit only text you intend OOMOL and Lingvanex to process.

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

  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Findings (5)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command performs remote script execution for an apparently unrelated CLI installation. It contains no Lingvanex API interaction, and nothing provided establishes this installation as a supporting dependency. The downloaded script's further behavior cannot be determined from this chunk.

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
91% confidence
Finding

The supplied code performs a login operation rather than the declared Lingvanex data-access functionality. Authentication could be a supporting implementation detail, but this chunk provides no evidence that the oo login supports Lingvanex or that the declared functionality is implemented.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The setup command pipes a remotely fetched, mutable script directly into Bash without integrity verification or an opportunity for inspection. Compromise of the installer distribution path could execute arbitrary code with the invoking user's privileges, exposing local files and credentials; conditional execution when the CLI is missing reduces exposure but does not remove the risk.

The action workflow sends supplied text to an external translation service without a privacy warning.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The workflow instructs the agent to submit action payloads through the OOMOL connector to Lingvanex, but does not warn that translation or language-detection inputs leave the user's environment. Labeling untagged actions as safe reads on line 46 overlooks this disclosure risk, even though those actions do not change provider state.

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.
