[thi.ng/egf] Potential arbitrary code execution of `#gpg`-tagged property values

Impact

Potential for arbitrary code execution in #gpg-tagged property values (only if decrypt: true option is enabled)

Patches

A fix has already been released as v0.4.0

Workarounds

By default, EGF parse functions do NOT attempt to decrypt values (since GPG is only available in non-browser env).

However, if GPG encrypted values are used/required:

1. Perform a regex search for #gpg-tagged values in the EGF source file/string and check for backtick (`) chars in the encrypted value string
2. Replace/remove them or skip parsing if present…
