Apify Threads Replies

• Outcome: Review
• Latest audit: Sep 16, 2026 · 5:42 AM UTC
• Version: 0.1.1

Overview

The skill does what it claims, but its examples put the user's Apify API token in URLs, which can leak through logs or diagnostics.

Review before installing or using. The skill appears purpose-aligned for collecting public Threads replies, but change the examples to use an Authorization header, use a narrowly scoped Apify token, avoid shell tracing around commands, and rotate any token that may already have appeared in logs or shared output.

A.I.G

Vulnerability Patterns

• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
