CVE-2017-17042 not yet assigned priority: Debian including 1 source packages (yard), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
lib/yard/core_ext/file.rb in the server in YARD before 0.9.11 does not block relative paths with an initial ../ sequence, which allows attackers to conduct directory traversal attacks and read arbitrary files.
