GoogleOSV:GHSA-6VJG-2Q57-RGFWMoodle allows attackers to cause a denial of service
iplookup/index.php in Moodle through 2.4.11, 2.5.x before 2.5.9, 2.6.x before 2.6.6, and 2.7.x before 2.7.3 allows remote attackers to cause a denial of service (resource consumption) by triggering the calculation of an estimated latitude and longitude for an IP address.
