Repliz Api

Security checks for vulnerabilities and agentic risk

Overview

The skill is a straightforward Repliz API reference, but it enables public posting, comment replies, and irreversible scheduled-post deletion without documented confirmation safeguards.

Install only if you are comfortable giving the agent Repliz API credentials that can manage connected social accounts. Before using it, require the agent to list the exact account, post, comment, or schedule item and ask for explicit confirmation before posting, replying, or deleting anything.

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
  • Tool MisuseTool Parameter Abuse, Chaining Abuse, Unsafe Defaults
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Tool Misuse
Confidence

Finding

The DELETE /public/schedule/{_id} endpoint gives the skill direct authority to remove scheduled posts, which is a powerful state-changing capability. Without strict confirmation, scoping, and validation of the target ID, an agent could be manipulated into deleting arbitrary scheduled content across connected accounts.

Missing User Warnings

Confidence
91% confidence
Finding

The skill enables actions that can publish content to connected social media accounts and reply publicly to comments, but the top-level description does not prominently warn users about these outward-facing, reputation-affecting effects. This increases the chance of accidental posting or engagement when an agent invokes the skill with insufficient user awareness or confirmation.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill documents an irreversible deletion endpoint but only notes the consequence inline, without a prominent safety warning or confirmation requirement. In an agent setting, this creates a real risk of accidental or unauthorized deletion of scheduled content, causing operational and reputational harm.
