An unauthenticated remote attacker can cause the server to contact loopback or private-network HTTP services. This can expose internal service behavior and enable interaction with resources that are not directly reachable by the attacker.","published":"2026-10-14T15:17:19.000Z","lastModified":"2026-10-14T16:17:45.000Z","status":"Deferred","sourceIdentifier":"88ee5874-cf24-4952-aea0-31affedb7ff2","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"cwe":["CWE-918"],"affected":[],"epss":{"score":0.00408,"percentile":0.34859,"date":"2026-10-26","history":[{"date":"2026-10-15","score":0.00408,"percentile":0.33513}]},"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 (0.41%).
