{"id":"CVE-2026-100632","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-100632","generatedAt":"2026-10-28T03:39:45.031Z","title":"Parse Server is an open-source backend server.","description":"Parse Server is an open-source backend server. In versions >= 9.0.0 and < 9.10.1-alpha.8, and in versions < 8.6.89, LiveQuery evaluates the protectedFields class-level permission against an incompletely resolved caller identity: the subscriber's roles are not resolved, and when a subscription does not supply its own session token the event payload is redacted against an anonymous identity even though the read was authorized against the connected user. As a result, field masks defined for a role, for authenticated users, or for a specific user are not applied, so an authenticated subscriber can receive field values that the REST API correctly withholds and can use a masked field to filter or watch a subscription. Only classes with LiveQuery enabled that define protectedFields under a role:, authenticated, or per-user group are affected; masks under the public (*) group are applied correctly. The issue is fixed in 9.10.1-alpha.8 and 8.6.89. As a workaround, additionally define the affected field masks under the public (*) group, or disable LiveQuery for classes whose class-level permissions rely on role-scoped, authenticated, or per-user protectedFields groups.","published":"2026-09-26T14:16:45.000Z","lastModified":"2026-09-30T17:23:09.000Z","status":"Awaiting Analysis","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":7.1,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/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-200"],"affected":[],"epss":{"score":0.00293,"percentile":0.21804,"date":"2026-10-27","history":[{"date":"2026-09-27","score":0.00293,"percentile":0.19648}]},"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 (0.29%).
