AI Media Generation

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward media-generation client that uses a disclosed AIsa API key and writes generated media locally when the user runs the commands.

Install only if you are comfortable sending prompts, referenced image URLs, task IDs, and generated-media requests to AIsa using your AISA_API_KEY. Avoid submitting sensitive or private content, and be careful with --download and --out because the script writes files locally and does not validate provider-returned download URLs or warn before overwriting a chosen path.

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

Tainted flow: 'req' from os.environ.get (line 65, credential/environment) → urllib.request.urlopen (network output)

Critical
Category
Data Flow
Confidence
90% confidence
Finding

Credentials or environment variables flow to a network sink. This is a high-confidence indicator of credential exfiltration.

Data Flow
Confidence
90% confidence
Finding

The downloader fetches an arbitrary URL returned by the remote task response and writes the response body directly to disk without validating the scheme, host, content type, or size. If the upstream service is compromised or returns attacker-controlled URLs, this can enable SSRF-style access to internal/local resources or untrusted file writes of unexpected content.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
93% confidence
Finding

The skill declares environment and network requirements and demonstrates outbound API usage, but it does not declare an explicit tool scope such as permissions or allowed-tools. That creates a governance gap: agents may be allowed to access secrets and make network calls without clear least-privilege boundaries, increasing the chance of unintended secret exposure or uncontrolled external requests.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

This markdown mixes English headings with core usage guidance in Chinese, including the introductory description and capability section. Because the skill does not offer an opt-in language choice or explain that it is intended for a Chinese-speaking audience, it may violate language/locale policy requirements.

External Transmission

Medium
Category
Data Exfiltration
Confidence
89% confidence
Finding

This example sends user prompts and the bearer token to an external third-party service, which is an actual data egress/security boundary crossing. In context, that is the intended function of the skill, so it is not inherently malicious, but it is still security-relevant because prompts or generated content may contain sensitive data and the API key is used for external transmission.

External Transmission

Medium
Category
Data Exfiltration
Confidence
90% confidence
Finding

The curl command performs a real outbound request carrying an authorization bearer token and user-supplied prompt to a remote service. This is expected for a media-generation skill, but it remains a true security-relevant behavior because it creates data exfiltration potential and dependency on an external provider's handling of submitted content.

External Transmission

Category
Data Exfiltration
Confidence
92% confidence
Finding

This command submits prompts, a referenced image URL, and an authorization token to an external video-generation API. Because the service also ingests an image URL, users may unknowingly send sensitive or private media references to a third party, making the egress risk more significant in practice.

Confidence
84% confidence
Finding

The polling request sends the bearer token and task identifier to the external service, which is still a real network transmission across a trust boundary. The payload is less sensitive than prompt/media submission, so impact is lower, but it still should be governed and disclosed.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

This markdown file describes sending user prompts and image URLs to external AIsa endpoints and downloading generated media, but it does not warn users that their prompts or referenced content will be transmitted to a third-party service. Under the markdown-specific missing-warning criterion, user-facing documentation should disclose behaviors that may affect privacy or data handling.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The natural-language content and usage instructions are presented in Chinese, which can amount to forcing a specific language for users without opt-in. The policy allows locale constraints when they are explicitly offered as a choice or clearly justified, which is not present here.

Content

No source excerpt is available for this finding.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
83% confidence
Finding

The code saves generated image bytes directly to a local path, but there is no confirmation prompt or user-facing disclosure at the point of write. While file output is part of the tool's purpose, the operation itself is silent and could affect user files if an explicit --out path is supplied.

Content

No source excerpt is available for this finding.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

When --download is used, the code automatically downloads the returned video URL and saves it to a local file, but there is no explicit runtime warning or confirmation before the write. Although the flag implies download intent, the code does not clearly disclose the destination write action to the user at execution time.
