Description

Although remote policy references are not retrieved during policy normalization, if they are manually retrieved via the API it can cause a denial of service attack if a huge policy is retrieved. Users are recommended to upgrade to version 3.2.3, which fixes this issue by imposing a default maximum size on data read from remote policy references.
