rxdb-premium@17.5.0
RxDB Premium
AI Security Review
scanned 13d ago · by lpm-firewall-aiThe package automatically downloads and executes remote code during installation, establishing a concrete install-time remote code execution path. This supports blocking publication as install-hook abuse.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package with lifecycle scripts enabled.
Impact
The downloaded code can execute with the privileges of the package installation process.
Mechanism
The postinstall script fetches JavaScript from premium.rxdb.info, writes it to scripts/installer.js, and the package lifecycle command invokes that file.
Attack narrative
During postinstall, the package retrieves executable JavaScript from a remote host and writes it into the package directory. The lifecycle command then runs that file, allowing remote content to execute during installation.
AI rationale
The package automatically downloads and executes remote code during installation, establishing a concrete install-time remote code execution path. This supports blocking publication as install-hook abuse.
