CVE-2025-71346

A flaw was found in Nokogiri, which packages a vulnerable version of libxml2. This heap-based buffer under-read vulnerability, located in the xmlSchemaIDCFillNodeTables function, can be triggered when processing untrusted XML Schemas or documents. A remote attacker could exploit this by providing...

CVE-2023-54354

A flaw was found in Nokogiri, specifically in its bundled libxml2 library when processing XML schemas. An attacker can exploit this by providing a specially crafted XML schema, leading to a NULL pointer dereference. This can cause the application to crash, resulting in a denial of service...

CVE-2022-50999
