In versions from 3.0.0 before 3.90.0 and canary versions before 4.0.0-canary.34, the duplicate operation copies values from a source document even when a field is hidden or its access.read or access.create rule rejects that value for the caller. The disableDuplicate setting does not prevent this access-control bypass. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.","published":"2026-10-06T17:17:21.000Z","lastModified":"2026-10-15T00:12:42.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":9.3,"severity":"CRITICAL","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:H/SI:H/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-284","CWE-863"],"affected":["payloadcms/payload"],"epss":{"score":0.00249,"percentile":0.16118,"date":"2026-10-26","history":[{"date":"2026-10-07","score":0.0031,"percentile":0.21875}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.25%).
