Bocha Web Search

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward web-search skill that discloses its Bocha API use, with privacy cautions around broad search activation but no evidence of hidden, persistent, or destructive behavior.

Before installing, understand that search terms derived from user prompts will be sent to Bocha's external API using your BOCHA_API_KEY. Use concise, non-sensitive queries and avoid searching secrets, credentials, private documents, or confidential business details unless you intend to disclose that content to the provider.

  • 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

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The skill explains that it performs web searches but does not clearly warn that user query content will be sent to an external provider. Without an explicit disclosure, users or higher-level agents may unknowingly transmit sensitive prompt contents off-platform, creating a privacy and data handling risk.

No source excerpt is available for this finding.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill instructs the agent to use web search whenever information is missing and even says to search when uncertain, which can cause unnecessary transmission of user queries to a third-party service. In contexts where user prompts may contain sensitive, personal, or proprietary information, this broad activation guidance increases privacy and data exposure risk even though the skill appears intended for normal search functionality.

External Transmission

Medium
Category
Data Exfiltration
Confidence
88% confidence
Finding

The skill is explicitly designed to send requests to an external endpoint, which is expected for a web search tool, but still constitutes a real data egress boundary. Because the transmitted payload contains user-derived queries, any sensitive information included in those queries may be exposed to the third-party API if not minimized or filtered.

Natural-Language Policy Violations

Low
Category

Confidence
81% confidence
Finding

The instruction hard-codes the fallback reply as a specific Chinese phrase with an English gloss, rather than letting the response match the user's chosen language. This can violate language-choice policy because it forces a locale-specific response without explicit user opt-in.
