Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Nokogiri versions before 1.13.2 are vulnerable because they bundle libxslt before 1.1.35 and libxml2 before 2.9.13 when using the packaged libraries (not system libraries). An attacker can cause denial of service by supplying untrusted XSL stylesheets for transformation. A libxml2 issue (CVE-2022-23308) may allow denial of service, memory disclosure, or code execution when untrusted documents are parsed with DTDVALID enabled and NOENT disabled. Upgrade to Nokogiri 1.13.2 or later.

Written 8 Nov 2026.
