CVE-2018-17567
Jekyll through 3.6.2, 3.7.x through 3.7.3, and 3.8.x through 3.8.3 allows attackers to access arbitrary files by specifying a symlink in the "include" key in the "_config.yml" file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.19%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
