Nokogiri prior to version 1.13.6 does not type-check all inputs into the XML and HTML4 SAX parsers, allowing specially crafted untrusted inputs to cause illegal memory access errors (segfault) or reads from unrelated memory. Version 1.13.6 contains a patch for this issue. As a workaround, ensure the untrusted input is a `String` by calling `#to_s` or equivalent.","published_at":"2022-05-20T00:00:00Z","last_modified_at":null,"cvss_v3_score":8.2,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":true,"ssvc_technical_impact":"partial","cwes":["CWE-241"],"nvd_references":["https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-xh29-r2w5-wx8m","https://github.com/sparklemotion/nokogiri/commit/83cc451c3f29df397caa890afc3b714eae6ab8f7","https://github.com/sparklemotion/nokogiri/commit/db05ba9a1bd4b90aa6c76742cf6102a7c7297267","https://github.com/sparklemotion/nokogiri/releases/tag/v1.13.6","https://securitylab.github.com/advisories/GHSL-2022-031_GHSL-2022-032_Nokogiri"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:03:11.180710Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"sparklemotion","vendor_name":"sparklemotion","product_slug":"nokogiri","product_name":"nokogiri","version_start":"< 1.13.6","version_start_inclusive":true,"version_end":"< 1.13.6","version_end_inclusive":true,"cpe23_uri":"cve5:sparklemotion:nokogiri:< 1.13.6:< 1.13.6"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-xh29-r2w5-wx8m","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/sparklemotion/nokogiri/commit/83cc451c3f29df397caa890afc3b714eae6ab8f7","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/sparklemotion/nokogiri/commit/db05ba9a1bd4b90aa6c76742cf6102a7c7297267","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/sparklemotion/nokogiri/releases/tag/v1.13.6","source_type":"PATCH","tags":["patch"]},{"url":"https://securitylab.github.com/advisories/GHSL-2022-031_GHSL-2022-032_Nokogiri","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2022-05-20T00:00:00Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:22:08.449389Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:22:08.449389Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:22:08.449389Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:03:11.180710Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:03:11.180710Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:03:11.180710Z","label":"SSVC decision revised","source":"vulnrichment"}]}
