{"id":"AZL-91080","summary":"CVE-2026-57234 affecting package rubygem-nokogiri for versions less than 1.19.4-1","details":"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.","modified":"2026-08-28T17:48:12.194358869Z","published":"2026-06-25T15:16:40Z","upstream":["CVE-2026-57234"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57234"}],"affected":[{"package":{"name":"rubygem-nokogiri","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/rubygem-nokogiri"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.19.4-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-91080.json"}}],"schema_version":"1.9.0"}
