Overview

@thi.ng/egf is an Extensible Graph Format

Affected versions of this package are vulnerable to Arbitrary Code Execution via gpg-tagged property values (only if decrypt: true option is enabled). By default the EGF parse functions do not attempt to decrypt values (since GPG is only available in a non-browser env).
