Seedance Video Generation

ReviewAudited by ClawScan on May 10, 2026.

Overview

The core video-generation function is coherent, but review is recommended because the artifacts include an unsafe macOS shell auto-open path and an under-declared Feishu chat-upload workflow using app credentials.

Install only if you are comfortable sending prompts and selected images to Volcengine. Avoid using unusual download paths on macOS until the auto-open shell call is fixed, and do not let the agent send generated videos to Feishu unless you have explicitly confirmed the recipient, file, and message.

Findings (4)

Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.

Concern

ASI05: Unexpected Code Execution

What this means

A crafted download path could cause unintended local shell command execution when the generated video is downloaded.

Why it was flagged

After a successful download, the tool automatically invokes a shell command built from the download path. Because the download directory can be user-supplied, shell metacharacters in the path could be interpreted on macOS.

Skill content

if sys.platform == "darwin":
    os.system(f'open "{filepath}"')

Recommendation

Replace os.system with a non-shell call such as subprocess.run(["open", str(filepath)]) or require explicit user confirmation before opening downloaded files.

Concern

ASI03: Identity and Privilege Abuse

What this means

If followed, generated videos may be uploaded to Feishu CDN and sent into a chat using configured Feishu app authority, potentially to an unclear recipient.

Why it was flagged

The bundled guide instructs sending generated videos through Feishu using OpenClaw Feishu app credentials. This external chat-upload capability is not part of the skill's stated description or declared credential/capability metadata.

Skill content

message(
  action="send",
  channel="feishu",
  filePath="/root/.openclaw/workspace/seedance_cgt-...mp4",
  message="视频说明文字"
)
...
使用配置在 OpenClaw 中的 `feishu.app_id` 和 `feishu.app_secret`。

Recommendation

Treat Feishu sending as a separate, explicit action: confirm the destination chat/recipient, file path, and user intent before uploading or sending any video.

Note

ASI03: Identity and Privilege Abuse

What this means

The skill needs access to a Volcengine Ark API key to create and manage video-generation tasks.

Why it was flagged

The tool requires an ARK_API_KEY and sends it as a bearer token to the Volcengine Ark API. This is expected for the stated Seedance integration, but the registry metadata says no required env vars or primary credential.

Skill content

key = os.environ.get("ARK_API_KEY")
...
"Authorization": f"Bearer {api_key}"

Recommendation

Use a scoped API key if available, keep it out of shared logs, and ensure the metadata accurately declares ARK_API_KEY as a required credential.

Note

ASI07: Insecure Inter-Agent Communication

What this means

Prompts and selected images may be sent to Volcengine for video generation.

Why it was flagged

When the user supplies a local image, the tool base64-encodes it and submits it to the external Seedance/Volcengine API as part of the generation request. This is purpose-aligned but involves sending selected local content to a provider.

Skill content

with open(p, "rb") as f:
    b64 = base64.b64encode(f.read()).decode("ascii")
...
result = api_request("POST", BASE_URL, body)

Recommendation

Only provide images and prompts you are comfortable sending to the Seedance/Volcengine service.
