Server-side request forgery (SSRF) vulnerability in feed-proxy.php in extjs 5.0.0.

The getTip() method of Action Columns of Sencha Ext JS 4 to 6 before 6.6.0 is vulnerable to XSS attacks, even when passed HTML-escaped data. This framework brings no built-in XSS protection, so the developer has to ensure that data is correctly sanitized. However, the getTip() method of Action Columns takes HTML-escaped data and un-escapes it. If the tooltip contains user-controlled data, an attacker could exploit this to create a cross-site scripting attack, even when developers took precautions and escaped data.

Directory traversal vulnerability in examples/layout/feed-proxy.php in Jack Slocum Ext 1.0 alpha1 (Ext JS) allows remote attackers to read arbitrary files via a .. (dot dot) in the feed parameter. NOTE: analysis by third party researchers indicates that this issue might be platform dependent.
