Poyo Wan 2 7 Image

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed PoYo image-generation helper that uses a user-provided API key and sends chosen payloads to PoYo only when requested.

Install only if you intend to use PoYo for Wan 2.7 image generation. Treat POYO_API_KEY as a secret, review payload JSON before submission, and avoid sending confidential prompts, private source image URLs, or private callback URLs unless you trust PoYo and the callback receiver.

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

Text-to-Image Example

bash
curl --fail-with-body --request POST \
  --url "https://api.poyo.ai/api/generate/submit" \
  --header "Authorization: Bearer YOUR_API_KEY" \
  --header "Content-Type: application/json" \

External Transmission

Medium
Category
Data Exfiltration
Confidence
88% confidence
Finding

The script transmits user-supplied JSON content from a local file to an external third-party service using curl, along with a bearer token for authentication. In a skill context with no explicit justification or user-consent flow, this creates a real data exfiltration risk because arbitrary contents of the provided payload file may be sent off-host.

Content

Scanner excerpt · scripts/submit_wan_2_7_image.sh (reported line 13)May include surrounding context.

sh
payload_file="$1"

curl --fail-with-body --request POST \
  --url "https://api.poyo.ai/api/generate/submit" \
  --header "Authorization: Bearer ${POYO_API_KEY}" \
  --header "Content-Type: application/json" \

External Transmission

Medium
Category
Data Exfiltration
Confidence
85% confidence
Finding

The hardcoded remote endpoint confirms that the script is designed to send data outside the local environment to api.poyo.ai. Even over HTTPS, sending potentially sensitive local payload data to a third party is a genuine security concern when the skill's purpose and data handling expectations are not clearly established.

Content

Scanner excerpt · scripts/submit_wan_2_7_image.sh (reported line 14)May include surrounding context.

sh
payload_file="$1"

curl --fail-with-body --request POST \
  --url "https://api.poyo.ai/api/generate/submit" \

  --header "Content-Type: application/json" \
  --data @"${payload_file}"

Context-Inappropriate Capability

Low
Category
Not specified by scanner
Confidence
79% confidence
Finding

No manifest is available, so the skill has no stated purpose or declared need for sensitive credential handling. The script requires POYO_API_KEY from the environment and uses it to authenticate an external API request, which is a capability that is not justified by any provided description.
