CVE-2025-49763

Description

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.
