Security audit

Zalo 3-Layer Anti-Ban Delivery (Zalo-Flow)

Security checks for vulnerabilities and agentic risk

Overview

This skill documents Zalo-Flow messaging safeguards and provides a related status check, with no hidden execution or unrelated data access.

Installing this skill alone does not enforce the advertised protections or guarantee account safety. Confirm that your Zalo-Flow deployment actually enforces them. The required personal access token is unused in the supplied example; clarify its need before providing it.

A.I.G

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

Description-Behavior Mismatch

High

Category: MCP Tool Poisoning
Confidence: 99% confidence
Finding: The only supplied operation is a remote system-status query. Although status checks could support a broader automation system, this chunk provides no connection to or implementation of the three declared protection layers, so its observable purpose materially differs from the description.
Content: No source excerpt is available for this finding.
