Webshare

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for Webshare read access, but its first-time setup tells users to run unverified remote installer scripts with local shell privileges.

Review the oo CLI installation path before installing. Prefer a pinned, signed, or checksum-verified installer from trusted documentation rather than piping remote content directly into a shell. Once installed and connected, the skill appears limited to Webshare read actions, but it can expose account profile, proxy configuration, proxy lists, and usage statistics through the connected OOMOL account.

Vulnerability Patterns

Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
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
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

External Script Fetching

High

Category: Supply Chain
Confidence: 97% confidence
Finding: The skill instructs users to install software via a remote script piped directly to a shell (curl ... | bash), which executes unreviewed code from the network with the user's privileges. If the install server, transport, DNS, or hosting is compromised, this becomes an immediate remote code execution path, and placing it inside a skill increases the chance an agent or user follows it without scrutiny.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The description says to use this skill for "ANY Webshare request" and "Whenever a task involves Webshare," which is very broad and lacks scope boundaries or exclusion conditions. This can overlap with many ordinary references to Webshare and does not clearly define when the skill should not activate.
