Searcher Os

Security checks for vulnerabilities and agentic risk

Overview

The skill matches its stated deal-management purpose, but it can change important business records and hide or advance deal workflow items without clear per-action user confirmation.

Review this before installing if you want every business-record change to require approval. The skill is coherent for Searcher OS users, but you should be comfortable with an agent reading sensitive deal/email/CIM data and performing some remote workflow updates without an additional confirmation prompt.

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

Finding

The skill exposes several state-changing operations that explicitly require no confirmation, including updating deal metadata and logging interactions. In an agent setting, this enables the model to make consequential business-record changes based on ambiguous prompts, hallucinated context, or prompt injection from untrusted email/CIM content, without an explicit user approval step.

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.

feed_dismiss_deal is auto-approved by default, letting the agent hide or discard candidate deals without an explicit user decision. In this M&A workflow context, silently dismissing opportunities can cause missed business opportunities and can be abused by malicious prompt content to bias or suppress results.

Finding

The task_update tool allows changing task state without confirmation, and the documentation notes that completing the last task may auto-advance the deal stage. That creates an indirect state-transition path where an agent can materially alter workflow status without a deliberate user approval, increasing the risk of unintended operational actions.

### Tasks
- **task_list** — List tasks for deals. Returns incomplete tasks by default. Params: `opportunity_id?` (uuid, filter to single deal), `stage?` (pipeline stage filter), `include_completed?` (default false), `limit?` (default 50, max 100), `offset?`
- **task_update** — Update a task. Mark complete/incomplete, change priority, set due date, or rename (manual tasks only). Completing the last task in a stage may auto-advance the deal. No confirmation needed. Params: `task_id` (uuid, required), `completed?` (boolean), `title?` (manual tasks only, max 500), `priority?` (1=High, 2=Medium, 3=Normal, manual tasks only), `due_date?` (YYYY-MM-DD|null)
