CVE-2026-57234 | BDVDB-2026-343391 Detail

sparklemotionnokogiri

Description#

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, the NONET parse option, which Nokogiri turns on by default for Nokogiri::XML::Schema (see CVE-2020-26247), was not correctly enforced on the JRuby implementation. As a result, a schema parsed with default options could still cause external resources to be fetched over the network, potentially enabling SSRF or XXE attacks. This vulnerability is fixed in 1.19.4.

Impact#

Per CVSS v3.1: confidentiality impact low, integrity impact none, availability impact none. Attack vector: network.

Weaknesses#

CWE-178 Improper Handling of Case Sensitivity
CWE-184 Incomplete List of Disallowed Inputs
CWE-611 Improper Restriction of XML External Entity Reference
