CVE-2025-6170 (opens in a new tab)How to fix?
Upgrade nokogiri to version 1.18.9 or higher.
Overview
nokogiri is a gem for parsing HTML, XML, SAX, and Reader.
Affected versions of this package are vulnerable to Stack-based Buffer Overflow due to unsafe use of strcpy() in the xmllint interactive shell command tool. An attacker can cause a crash by providing an overly long argument to any shell command during an interactive session.
Note:
This vulnerability affects only the interactive shell and requires that an attacker can influence or control the command input to xmllint, which is uncommon in typical deployments.
