Summary
Nokogiri vulnerable to libxslt protection mechanism bypass
Details

A dependency of Nokogiri, libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded.

Severity
9.8 (Critical)
