Attackers can use mixed-case URL schemes in resources.GetRemote calls to fetch from restricted IP addresses like localhost.\nA flaw was found in Hugo. Case-sensitive validation in the URL deny rule mechanism allows an attacker to bypass access restrictions. By supplying mixed-case URL schemes when fetching remote resources, an attacker can access restricted network destinations, such as localhost or internal IP addresses. This may lead to unauthorized access to internal network services and information disclosure.\nRed Hat Product Security rates this flaw Moderate. In historical Hummingbird Hugo builds, an untrusted URL passed to resources.GetRemote could bypass the default IP-literal deny rule by using a mixed-case scheme, allowing the build process to fetch restricted network resources. The current Hummingbird Hugo package contains the fix.
