@decocms/blocks-cli@7.55.2
Deco codegen (generate-blocks, generate-schema, generate-invoke) and Fresh-to-TanStack migration tooling
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package is not malicious by static inspection, but two user-controlled CLI values reach shell commands unsafely. Downgrade pending remediation because exploitation can yield local command execution during explicit use.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs the affected CLI with a crafted --since or --branch argument.
Impact
An attacker who controls CLI arguments can run commands with the invoking user's permissions.
Mechanism
Shell command injection through interpolated CLI arguments.
AI rationale
The package is not malicious by static inspection, but two user-controlled CLI values reach shell commands unsafely. Downgrade pending remediation because exploitation can yield local command execution during explicit use.
Evidence
scripts/sync-blocks-to-kv.tsscripts/deco-migrate-cli.ts
Decision evidence
public snapshotAI called this Suspicious at 93.0% confidence as Critical Vulnerability with low false-positive risk.
Evidence for warning
- The KV sync CLI interpolates the user-controlled --since value into an execSync shell command.
- The migration helper interpolates an optional --branch value into a git clone shell command.
- The manifest exposes these tools as user-invoked CLI commands.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- The reviewed network and environment use is tied to explicit deployment and cache-purge options, not automatic execution.
- The dynamic require and package-manager spawn findings are test-only fixtures.
