@decocms/blocks-cli@7.62.3
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 shown to be malware, but it contains a concrete user-invoked command-injection vulnerability. Automatic installation, persistence, and exfiltration were not found.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A caller runs deco-sync-blocks-to-kv with a crafted --since value.
Impact
Commands can execute with the invoking user's permissions.
Mechanism
Unescaped CLI input is interpolated into execSync.
AI rationale
The package is not shown to be malware, but it contains a concrete user-invoked command-injection vulnerability. Automatic installation, persistence, and exfiltration were not found.
Evidence
scripts/sync-blocks-to-kv.tspackage.json
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Critical Vulnerability with low false-positive risk.
Evidence for warning
- The user-controlled --since value is interpolated into an execSync shell command without escaping.
- The vulnerable script is exposed as the deco-sync-blocks-to-kv CLI.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- Cloudflare token use is confined to an explicit content-sync CLI operation.
- No source evidence shows automatic credential exfiltration, stealth persistence, or install-time execution.
