Attackers can write a reserved field that makes reads of an object fail on MongoDB, disrupting queries on that class for all users, or clear their own account lockout state and password history to bypass lockout and password policies.","published":"2026-10-25T14:16:55.000Z","lastModified":"2026-10-26T14:03:57.000Z","status":"Awaiting Analysis","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":6.3,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-20"],"affected":[],"epss":{"score":0.00344,"percentile":0.27667,"date":"2026-10-26","history":[{"date":"2026-10-26","score":0.00344,"percentile":0.27667}]},"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 (0.34%).
