{"id":"AZL-91083","summary":"CVE-2026-57235 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, Nokogiri::XML::NodeSet#[] (and its alias #slice) checked the requested index against the node set's bounds using a 32-bit-truncated copy of the index. A large negative index could pass the check and then be used at full width, reading outside the node set's storage. On CRuby this is an out-of-bounds read that typically crashes the process; on JRuby it is not memory-unsafe but returns an incorrect node. This vulnerability is fixed in 1.19.4.","modified":"2026-08-28T17:48:11.998928616Z","published":"2026-06-25T15:16:40Z","upstream":["CVE-2026-57235"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57235"}],"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-91083.json"}}],"schema_version":"1.9.0"}
