NVD Description
Note: Versions mentioned in the description apply only to the upstream eks-distro-1.33-coredns-1.13.2-licenses package and not the eks-distro-1.33-coredns-1.13.2-licenses package as distributed by Minimos.
CoreDNS is a DNS server that chains plugins. Prior to version 1.14.2, a logical vulnerability in CoreDNS allows DNS access controls to be bypassed due to the default execution order of plugins. Security plugins such as acl are evaluated before the rewrite plugin, resulting in a Time-of-Check Time-of-Use (TOCTOU) flaw. This issue has been patched in version 1.14.2.
