If no explicit error-email recipient is configured, a mail server is configured, and the server accepts an attacker-chosen Host, an attacker whose request triggers a cold start can direct later error emails to an address under their control for that application's lifetime. Emails disclose error and request metadata; on engines/versions where scope dumps render, they may also disclose configuration secrets and other users' session/cookie data. On the Lucee 7 engine, scope dumps fail to render, limiting disclosure to header fields. This is fixed in 4.1.2.","published":"2026-10-16T04:18:32.000Z","lastModified":"2026-10-19T19:17:23.000Z","status":"Deferred","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-348"],"affected":[],"epss":{"score":0.00136,"percentile":0.03037,"date":"2026-10-26","history":[{"date":"2026-10-16","score":0.00136,"percentile":0.02728}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.14%).
