CVE-2025-49763
Published:June 19, 2025
Updated:June 07, 2026
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.
