[thi.ng/egf] Potential arbitrary code execution of `#gpg`-tagged property values
🔗 CVE IDs covered (1)
📋 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:
- Perform a regex search for
#gpg-tagged values in the EGF source file/string and check for backtick (`) chars in the encrypted value string - Replace/remove them or skip parsing if present...
