Information Exposure

Overview parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js. Affected versions of this package are vulnerable to Information Exposure in the query execution layer. An attacker can obtain internal database error details, including error...

GHSA-9CP7-3Q5W-J92G parse-server: Malformed `$regex` query leaks database error details in API response

Impact A malformed $regex query parameter e.g. abc causes the database to return a structured error object that is passed unsanitized through the API response. This leaks database internals such as error messages, error codes, code names, cluster timestamps, and topology details. The vulnerabilit...

CVE-2026-30229

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.6 and 9.5.0-alpha.4, the readOnlyMasterKey can call POST /loginAs to obtain a valid session token for any user. This allows a read-only credential to impersonate arbitrary...

CVE-2026-30228

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.5 and 9.5.0-alpha.3, the readOnlyMasterKey can be used to create and delete files via the Files API POST /files/:filename, DELETE /files/:filename. This bypasses the...

CVE-2026-29182

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.4 and 9.4.1-alpha.3, Parse Server's readOnlyMasterKey option allows access with master-level read privileges but is documented to deny all write operations. However, some...
