dasyl
Dasyl is a fast, opinionated CLI for creating, configuring, and releasing modern development projects in seconds.
This report shows the evidence for dasyl@2.1.3. 0 of 5 known versions are blocked or flagged. See all versions.
AI Security Review
scanned 11d ago · by lpm-firewall-aiThe source shows conditional credential exposure because an unrestricted DASYL_API_URL override receives the saved token without a recipient-specific guard. The default endpoint appears package-aligned, so this supports a warning rather than a block.
Static reason
One or more suspicious static signals were detected.
Trigger
Any CLI process exit starts the detached telemetry helper when a saved token exists.
Impact
If DASYL_API_URL points to an unrelated endpoint, that recipient receives the saved token. No recipient-specific consent guard is shown.
Mechanism
The helper reads the token from the local Dasyl configuration and sends it as a bearer credential to DASYL_API_URL, which has no destination allowlist.
AI rationale
The source shows conditional credential exposure because an unrestricted DASYL_API_URL override receives the saved token without a recipient-specific guard. The default endpoint appears package-aligned, so this supports a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest points to a CLI entrypoint and contains no install lifecycle hook.
- The CLI starts a detached telemetry helper whenever process.exit is called.
- The helper reads the saved Dasyl API token and sends it as a bearer token to the configured API base URL, without a recipient allowlist or separate consent check.
- Login accepts a Dasyl token and verifies it against the same configurable API base URL before saving it.
- Account queries and build telemetry also use the configured Dasyl API; build events include the project name and framework.
Evidence against
- The default API host is used consistently for Dasyl login, account queries and telemetry, which is consistent with the package’s service.
- The telemetry helper sends command status, platform and Node version; inspected source does not establish a default transfer of hostnames, home paths or secrets.
- The credential exposure depends on DASYL_API_URL being set to an unrelated endpoint; the source does not show that override being set by default.
