Seafile Library

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Seafile library helper, but users should be careful because it can download files locally and upload or overwrite files in the connected Seafile library.

Install only if you intend to let the agent access the Seafile library covered by the repo token. Use the narrowest repo token available, confirm target paths before uploads or downloads, and avoid replace=1 unless overwriting the remote file is intentional.

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

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The skill enables both downloading remote files to the local filesystem and uploading local files to a remote Seafile server, but the description does not prominently warn about those side effects at the point where users decide whether to invoke it. That omission can cause an agent or operator to use the skill for 'search' while overlooking that the same skill also performs data exfiltration or local file writes, increasing the risk of unintended disclosure or filesystem modification.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The default prompt and description encourage use of the skill whenever an agent 'needs' Seafile access, but they do not impose narrow trigger conditions, approval requirements, or data-sensitivity constraints. Because the skill supports search, download, and upload using a repo token and implicit invocation is enabled, broad invocation wording increases the chance an agent will overuse it for file access operations that may expose or modify repository contents unnecessarily.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: This markdown file includes multipart upload examples, including replace=1, which can overwrite existing content in Seafile. The surrounding text does not warn the user that running the command may modify or replace remote data, so the skill description omits a safety-relevant disclosure for a data-affecting operation.
Content: No source excerpt is available for this finding.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 90% confidence
Finding: This markdown file describes how to upload files and notes that replace=1 overwrites an existing file with the same name, which can affect user data and system integrity. The section explains mechanics but does not include an explicit caution or warning to users about the overwrite risk.
Content: No source excerpt is available for this finding.

Missing User Warnings

Low

Category: Not specified by scanner
Confidence: 82% confidence
Finding: The example downloads remote content to LOCAL_FILE using -o, which performs a local file write and may overwrite an existing file. The documentation presents this as a copy-paste command pattern but does not disclose the local filesystem impact or advise checking the destination path first.
