BIT-PARSE-2026-30229 Parse Server: Endpoint `/loginAs` allows `readOnlyMasterKey` to gain full read and write access as any user

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, the readOnlyMasterKey can call POST /loginAs to obtain a valid session token for any user. This allows a read-only credential to impersonate arbitrary users...

BIT-PARSE-2026-30228 Parse Server: File creation and deletion bypasses `readOnlyMasterKey` write restriction

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, the readOnlyMasterKey can be used to create and delete files via the Files API POST /files/:filename, DELETE /files/:filename. This bypasses the read-only...

BIT-PARSE-2026-29182 Parse Server: Cloud Hooks and Cloud Jobs bypass `readOnlyMasterKey` write restriction

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, Parse Server's readOnlyMasterKey option allows access with master-level read privileges but is documented to deny all write operations. However, some endpoint...

golang: net/url: Memory exhaustion in query parameter parsing in net/url

A flaw was found in the net/url package in the Go standard library. The package does not enforce a limit on the number of unique query parameters it parses. A Go application using the net/http.Request.ParseForm method will try to process all parameters provided in the request. A specially crafted...

CVE-2026-30925

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.0-alpha.14 and 8.6.11, a malicious client can subscribe to a LiveQuery with a crafted $regex pattern that causes catastrophic backtracking, blocking the Node.js event loop. This...

Parse Server vulnerable to user enumeration via email verification endpoint

Impact The email verification endpoint /verificationEmailRequest returns distinct error responses depending on whether an email address belongs to an existing user, is already verified, or does not exist. An attacker can send requests with different email addresses and observe the error codes to...

Operation on a Resource after Expiration or Release

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 Operation on a Resource after Expiration or Release due to the recovery code. An attacker can repeatedly gain unauthorized...

GHSA-4HF6-3X24-C9M8 Parse Server's MFA recovery codes not consumed after use

Impact When multi-factor authentication MFA via TOTP is enabled for a user account, Parse Server generates two single-use recovery codes. These codes are intended as a fallback when the user cannot provide a TOTP token. However, recovery codes are not consumed after use, allowing the same recover...

GHSA-R2M8-PXM9-9C4G Parse Server has a protected fields bypass via dot-notation in query and sort

Impact The protectedFields class-level permission CLP can be bypassed using dot-notation in query WHERE clauses and sort parameters. An attacker can use dot-notation to query or sort by sub-fields of a protected field, enabling a binary oracle attack to enumerate protected field values. This...
