AIsa Tavily

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward AIsa-backed web research helper that sends search queries or supplied URLs to AIsa, which fits its stated purpose.

Install only if you are comfortable using AIsa as a third-party research provider. Do not pass private document links, localhost/internal URLs, secret-bearing query strings, or sensitive searches unless you intend to share them with AIsa.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
88% confidence
Finding

The skill declares required environment variables and implicitly supports networked research, but it does not define an explicit tool scope such as allowed-tools or permissions. In an agent ecosystem, this can cause overbroad execution authority or ambiguous policy enforcement, increasing the chance that the skill is invoked with more capabilities than intended.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
85% confidence
Finding

The description uses broad activation terms like search, synthesis, competitor scans, and trend discovery, which can match many common user requests. This raises the risk of over-triggering the skill in contexts where web access, external data retrieval, or use of the API key is unnecessary, expanding attack surface and risking unintended data exposure.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
84% confidence
Finding

The 'When to use' section lists broad positive triggers but does not define boundaries or exclusion conditions. In agent routing systems, this ambiguity can cause the skill to be selected for generic research tasks, leading to unnecessary external calls, excess privilege use, and less predictable behavior.

External Transmission

Medium
Category
Data Exfiltration
Confidence
84% confidence
Finding

This code performs an outbound HTTPS request to an external API and includes user-provided URLs in the request body. While external transmission is expected for this skill's functionality, it is still security-relevant because it can leak sensitive targets or metadata to a third party if users are not clearly informed or if untrusted inputs are passed through unchecked.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The script transmits user-supplied URLs to a third-party service without any explicit disclosure, confirmation, or guardrail beyond basic CLI usage. In a research/extraction skill, URLs may contain sensitive internal endpoints, private document links, or query-bearing URLs, so silent forwarding to an external API creates a real data exposure and privacy risk.

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
