Nextcloud Integration Helper

Security checks for vulnerabilities and agentic risk

Overview

This skill is an instruction-only helper for planning Nextcloud support, with no executable code or hidden data access, though its automatic trigger terms are broader than ideal.

Before installing, be aware that the skill may activate on generic support or feature-request language. It is otherwise narrowly about Nextcloud support planning and does not ship code or request sensitive access.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill description uses broad activation terms such as 'software-and-data', 'enhancement', 'add', and 'support', which are common across many unrelated requests. This can cause unintended invocation, routing users into this skill when they did not ask for Nextcloud-specific help, creating context confusion and increasing the chance of irrelevant or unsafe downstream guidance.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The keyword list includes high-collision generic words like 'add', 'support', 'feature', 'request', 'related', and 'problem' without any scoping condition. In a skill-routing system, these broad triggers can match a large volume of unrelated prompts, causing accidental activation and misapplication of the skill's instructions.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The default prompt includes a broad invocation phrase tied to common terms like 'help,' 'support,' 'analysis,' and 'workflow,' which can cause the skill to activate in many unrelated conversations. This increases the chance of unintended routing of user requests and accidental exposure of the skill's behavior in contexts where the user did not explicitly ask for it.

Vague Triggers

Category
Not specified by scanner
Confidence
97% confidence
Finding

Enabling implicit invocation without clear constraints allows the skill to be triggered automatically based on vague matches rather than explicit user intent. In this skill, the broad enhancement-oriented description compounds that risk, making mis-invocation more likely and potentially causing unintended actions, recommendations, or data handling in unrelated sessions.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger phrase is broad enough to match ordinary user language about adding support or needing help, which can cause the skill to activate outside its intended scope. In an agent system, overly broad activation can misroute requests, cause irrelevant guidance to be injected, and increase the chance that a less-appropriate skill handles sensitive or unrelated tasks.
