Description The issue allows attackers to access arbitrary files by specifying a symlink in the include key in the config.yml file.

Recommendations For Jekyll versions 3.6.2 and earlier, update to a version later than 3.6.2. For Jekyll versions 3.7.x through 3.7.3, update to a version later than 3.7.3.
