What is CVE-2024-28247?

A vulnerability in Pi-hole allows authenticated users to read internal server files arbitrarily due to improper handling of local file updates. When updating from a file containing non-domain lines, the system may output five of these lines directly to the interface. This presents a significant security risk as it enables exposure of potentially sensitive information to users with access rights. Users are advised to update to version 5.18 to mitigate this issue.
