CVE-2019-11879 describes a directory traversal vulnerability in the WEBrick gem 1.4.2 for Ruby, affecting ruby-lang webrick. This medium-severity vulnerability (CVSS 5.5) requires local access to create a symlink, allowing an attacker to read files outside the web root. While the vendor considers it analogous to Apache's Options FollowSymlinks and "not a problem," it could lead to high confidentiality impact. There is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed on CISA's KEV catalog.
