Security audit

Teable

Security checks for vulnerabilities and agentic risk

Overview

Teable data changes require approval, but first-time setup directs the agent to execute unverified remote software without a separate approval step.

Review the setup before installing. Approve and verify the CLI separately, including any additional agent skills it installs; the remote installers could not be inspected. OOMOL mediates access to your connected Teable account, so limit that connection to the permissions needed. Keep the documented approval steps for edits and deletions.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
95% confidence
Finding

The supplied chunk performs remote installer execution, not Teable data operations. Although dependency installation can be a supporting implementation detail, nothing supplied establishes this installer's role in accessing Teable. The downloaded script is not included, so its additional behavior cannot be assessed.

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

- `create_records` — Create one or more records in a Teable table using provider-defined field values. [write]
- `delete_record` — Permanently delete one Teable record by table ID and record ID. [destructive]
- `get_current_user` — Get the Teable user associated with the connected personal access token.
- `get_record` — Get one Teable record by table ID and record ID.
- `list_bases` — List the Teable bases in a space accessible to the connected token.
- `list_records` — List records in a Teable table with optional projection, view, filtering, sorting, and offset pagination.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an HTTPS response directly into bash executes mutable remote code with the invoking user's privileges, without a pinned version or independent integrity verification. A compromised distribution endpoint or malicious installer update could access local data or modify the system; the missing-CLI condition reduces exposure frequency but does not remove this supply-chain risk.

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

Medium
Category
Output Handling
Confidence
93% confidence
Finding

The fallback directs the agent to execute a remote installer without explaining its local execution privileges or requiring approval for software installation. Although conditional on a missing dependency, this expands a Teable data request into local system changes that the user may not have authorized; the declared oo-only tool restriction may constrain execution but is not an installation-consent safeguard.

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.
