Pub Discord

Security checks for vulnerabilities and agentic risk

Overview

The skill appears to be a broad SkillBoss API integration, but it is packaged as a Discord skill and includes powerful external actions like email, SMS, document processing, and model calls.

Review this carefully before installing. Treat it as a broad SkillBoss external API skill, not a Discord-only skill. Do not provide `SKILLBOSS_API_KEY` or run the examples unless you are comfortable sending prompts, media, document URLs, search queries, email contents, and phone numbers to the SkillBoss service and possibly downstream providers. Avoid the `run.mjs` examples unless you have verified exactly which executable will run.

# SkillBoss

One API key, 50+ models across providers (Bedrock, OpenAI, Vertex, ElevenLabs, Replicate, Minimax, and more). Call any model directly by ID, or use smart routing to auto-select the cheapest or highest-quality option for a task.

**Base URL:** `https://api.heybossai.com/v1`
**Auth:** `-H "Authorization: Bearer $SKILLBOSS_API_KEY"`

Technical Analysis

The package declares its name as discord and claims that it controls Discord, including sending messages, adding reactions, posting stickers, and uploading emojis. The implementation documentation instead describes a SkillBoss model-aggregation API hosted at api.heybossai.com.

No Discord endpoint, Discord authentication mechanism, or Discord operation is present in the audited files. The declared identity therefore does not accurately represent the behavior users and agents are being instructed to authorize. This is especially relevant because the skill requests Bash access and access to the SKILLBOSS_API_KEY environment variable.

The package is documentation-only and does not automatically transmit the credential merely by being loaded. The risk arises when an agent trusts the declared Discord identity and executes the documented Bash and cURL commands.

Attack Path

  1. A user or agent selects the package expecting a Discord-control skill.
  2. Based on the declared metadata, the pack ...[truncated 1155 chars]

Remediation Suggestions

  1. Rename the skill to accurately identify it as a SkillBoss or model-aggregation API integration.
  2. Replace the Discord-focused description with a precise list of the implemented model, search, scraping, email, SMS, and document-processing capabilities.
  3. If Discord support is intended, implement and separately document the relevant Discord endpoints, authentication model, permissions, and operations.
  4. Clearly disclose that user content is transmitted to api.heybossai.com and may be processed by downstream model providers.
  5. Document which operations may incur charges or cause external side effects, particularly email and SMS operations.
  6. Apply least privilege by limiting Bash access where possible and exposing narrowly scoped tools for individual API operations.

run.mjs --model mm/i2v --prompt "Zoom in slowly" --image "https://example.com/photo.jpg" --output video.mp4

Technical Analysis

The documentation repeatedly directs the agent to execute run.mjs as a bare command. The audited project does not contain a run.mjs file and does not identify a verified package, installation source, version, checksum, or absolute path that should provide the command.

A shell resolves a bare executable name by searching directories listed in the PATH environment variable. If an attacker can place a malicious executable named run.mjs in an earlier PATH directory, the legitimate-looking documented command will execute the attacker's program. The malicious process inherits the invoking agent's user privileges, environment variables, working directory access, and other process-l ...[truncated 1728 chars]

Remediation

Remediation Suggestions

  1. Bundle the reviewed run.mjs implementation within the project rather than relying on an unidentified global command.
  2. Invoke it through a fixed project-relative path, such as node ./scripts/run.mjs, after resolving and validating the project root.
  3. Do not add the current working directory or other user-writable directories to PATH.
  4. If the executable comes from a dependency, document its exact package name and trusted registry, pin an immutable version, and verify its integrity.
  5. Validate the executable's ownership and permissions before invocation, and reject tools located in writable or unexpected directories.
  6. Launch the command with a minimal environment containing only the variables required for the requested operation.
  7. Restrict filesystem and network privileges through sandboxing or containerization.
  8. Update every affected documentation example to use the same verified, explicit executable path.

Finding

The skill is labeled and described as a Discord-control integration, but the contents actually expose a broad third-party API with unrelated capabilities including chat, search, document parsing, email, and SMS. This is dangerous because it creates a severe scope mismatch: users or calling agents may grant trust and invoke the skill expecting limited Discord actions, while the skill actually enables outbound communications and transmission of arbitrary content to external services.
