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

A flaw was found in Nokogiri. An integer overflow vulnerability in packaged libxml2 buffer handling functions allows a remote attacker to cause out-of-bounds memory writes. By crafting specially designed, large XML files, an attacker can trigger buffer overflows, leading to potential information...

CVE-2022-50998

A flaw was found in Nokogiri, a Ruby gem for parsing XML and HTML documents.

This could lead ...

CVE-2026-79772

A flaw was found in Nokogiri. This vulnerability occurs because the canonicalize method fails to properly check the return value from an internal XML processing function, returning an empty string on failure instead of an error. A remote attacker could exploit this by providing specially crafted...
