Hi,
The following vulnerability was published for ruby-nokogiri.
CVE-2020-26247[0]:
| Nokogiri is a Rubygem providing HTML, XML, SAX, and Reader parsers
| with XPath and CSS selector support. In Nokogiri before version
| 1.11.0.rc4 there is an XXE vulnerability. XML Schemas parsed by
| Nokogiri::XML::Schema are trusted by default, allowing external
| resources to be accessed over the network, potentially enabling XXE or
| SSRF attacks. This behavior is counter to the security policy followed
| by Nokogiri maintainers, which is to treat all input as untrusted by
| default whenever possible. This is fixed in Nokogiri version
| 1.11.0.rc4.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
