Apache Traffic Server: Remote DoS via memory exhaustion in ESI Plugin
ESI plugin does not have the limit for maximum inclusion depth, and that allows excessive memory consumption if malicious instructions are inserted.

Users can use a new setting for the plugin (--max-inclusion-depth) to limit it.
This issue affects Apache Traffic Server: from 10.0.0 through 10.0.5, 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.
