An authorization bypass flaw was found in Istio. This flaw allows an attacker to craft an HTTP request that defines a certain pattern of escaped characters in the URI path (such as %2F, %2f, %5C, or %5c), allowing them to bypass the authorization service. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
