CVE-2025-31698

ACL configured in ip_allow.config or remap.config does not use IP addresses that are provided by PROXY protocol.

Users can use a new setting (proxy.config.acl.subjects) to choose which IP addresses to use for the ACL if Apache Traffic Server is configured to accept PROXY protocol.
This issue affects undefined: from 10.0.0 through 10.0.6, from 9.0.0 through 9.2.10.

Users are recommended to upgrade to version 9.2.11 or 10.0.6, which fixes the issue.
