This leaves open the possibility of a denial of service type attack, where a malicious user crafts a message containing a very large number of message attachments. From the 3.3.4 and 3.2.11 releases, a default limit of 50 message attachments is enforced. This is configurable via the message property \"attachment-max-count\".","published":"2019-11-06T21:15:11.000Z","lastModified":"2026-06-17T02:14:35.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},"cwe":["CWE-770"],"affected":["apache/cxf","oracle/commerce guided search","oracle/flexcube private banking","oracle/retail order broker"],"epss":{"score":0.06257,"percentile":0.93527,"date":"2026-10-27","history":[]},"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 (6.26%).
