CVE-2021-32806 Information

Description

Products.isurlinportal is a replacement for isURLInPortal method in Plone. Versions of Products.isurlinportal prior to 1.2.0 have an Open Redirect vulnerability. Various parts of Plone use the ‘is url in portal’ check for security mostly to see if it is safe to redirect to a url. A url like https://example.org is not in the portal. The url https:example.org without slashes is considered to be in the portal. When redirecting some browsers go to https://example.org others give an error. Attackers may use this to redirect victims to their site especially as part of a phishing attack. The problem has been patched in Products.isurlinportal 1.2.0.
