CVE-2026-58178 is a high-severity vulnerability in the Apache Traffic Server ESI plugin. The flaw allows the plugin to recurse without bound while processing ESI content and to fetch attacker-controlled URLs. This creates a condition where crafted input can drive repeated recursive processing and cause the server to initiate outbound requests under attacker influence. The issue affects Apache Traffic Server versions 8.0.0 through 8.1.9, 9.0.0 through 9.2.14, and 10.0.0 through 10.1.3. The vulnerability is classified as CWE-674, Uncontrolled Recursion.
