Vida

Security checks for vulnerabilities and agentic risk

Overview

The Vida workflow is coherent, but automatic installation and undisclosed changes to other agent skills warrant review.

Review and install the CLI separately before using this skill, and decide whether OOMOL should manage additional agent skills. The publisher documents OO_SKILLS_SYNC_DISABLED=1 to disable startup synchronization. Connecting Vida entrusts OOMOL with its credentials and account access. The bundled instructions were fully inspected, but the remote installers and released binary 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
Vulnerability Patterns

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
95% confidence
Finding

The supplied chunk runs an Oomol installer and contains no Vida search or reading functionality. Although dependency installation can be a supporting implementation detail, nothing supplied establishes this installer's relationship to Vida. The remote script's contents are unavailable, so its additional behavior cannot be determined.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
85% confidence
Finding

The supplied chunk only invokes a login command; it contains no Vida search or read operations and establishes no connection between oo and Vida. Authentication could be a supporting implementation detail, but the supplied code presents it as the entire behavior rather than as part of the declared functionality.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a mutable remote script directly into bash executes its contents with the agent process's local privileges without prior verification or review. HTTPS protects transport but does not prevent a compromised publisher or distribution endpoint from serving malicious code; the PowerShell setup command has the same underlying risk.

The setup workflow executes downloaded installation scripts without warning the user about remote code execution and local system changes.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The fallback instructs the agent to execute remotely supplied shell or PowerShell code without first explaining the local changes or obtaining explicit installation approval. Although installation supports the legitimate connector workflow and occurs only when the CLI is missing, a read-oriented Vida request should not implicitly authorize arbitrary local installer execution.

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.
