Description

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...
