Vulnerability Type: Supply-chain risk from an unpinned dependency
Risk Level: MediumVulnerable Code
text - **If not installed**, prompt: use npx -y @alipay/agent-payment@latest install to install and enable the Alipay AI wallet capability, then enable the Alipay payment functionThe original instruction contains the executable command:
bash npx -y @alipay/agent-payment@latest installTechnical Analysis
The Skill directs the Agent to retrieve and execute the mutable
latestrelease of@alipay/agent-payment. The-yoption suppresses the normal confirmation prompt. The reviewed project does not pin an exact package version and provides no lockfile, integrity hash, signature requirement, or vendored source through which the executed package can be verified.Consequently, the code executed during installation may differ from the code available when this Skill was audited. This creates a supply-chain boundary in which a compromised package publisher account, registry compromise, or malicious future release could cause arbitrary package lifecycle or CLI code to run locally.
Attack Path
- A user invokes the Skill while the required Alipay capability is unavailable.
- The Skill instructs the Agent to install the missing capability.
- The Agent runs
npx -y @alipay/agent-payment@latest install. - npm resolves
latestat execution time and downloads the corresponding third-party package. npxexecutes the downloaded package without an interactive confirmation prompt.- If that release is compromised, its code executes with the operating-system permissions and environmental access of the Agent process.
Impact Assessment
A malicious dependency release could execute arbitrary code with the privileges of the account running the Agent. Depending on that account's permissions and runtime environment, this could permit access to readable files, enviro ...[truncated 339 chars]

Remediation Suggestions
-
Replace
@latestwith an exact, reviewed package version, for example:bash npx @alipay/agent-payment@X.Y.Z install -
Verify the selected release's provenance, publisher, signatures where supported, and registry integrity metadata before execution.
-
Maintain a lockfile or equivalent approved-dependency manifest with integrity hashes.
-
Remove
-yso installation requires explicit confirmation. -
Clearly disclose that installation executes third-party code and obtain informed user approval before running it.
-
Run installation with least privilege in a sandbox or restricted environment, without unnecessary secrets or filesystem access.
-
Establish a controlled dependency-update process in which new versions are reviewed and tested before changing the pinned version.
