GraphQL API endpoint ignores CORS origin restriction

Impact The GraphQL API endpoint does not respect the allowOrigin server option and unconditionally allows cross-origin requests from any website. This bypasses origin restrictions that operators configure to control which websites can interact with the Parse Server API. The REST API correctly...

GHSA-Q3P6-G7C4-829C GraphQL API endpoint ignores CORS origin restriction

Impact The GraphQL API endpoint does not respect the allowOrigin server option and unconditionally allows cross-origin requests from any website. This bypasses origin restrictions that operators configure to control which websites can interact with the Parse Server API. The REST API correctly...

Origin Validation Error

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 Origin Validation Error via the GraphQL API endpoint ignoring the configured CORS allowOrigin restriction. An attacker can...

Race Condition

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 Race Condition in the handling of concurrent LiveQuery subscribers due to shared mutable state. An attacker can access...

LiveQuery protected field leak via shared mutable state across concurrent subscribers

Impact When multiple clients subscribe to the same class via LiveQuery, the event handlers process each subscriber concurrently using shared mutable objects. The sensitive data filter modifies these shared objects in-place, so when one subscriber's filter removes a protected field, subsequent...

GHSA-M983-V2FF-WQ65 LiveQuery protected field leak via shared mutable state across concurrent subscribers

Impact When multiple clients subscribe to the same class via LiveQuery, the event handlers process each subscriber concurrently using shared mutable objects. The sensitive data filter modifies these shared objects in-place, so when one subscriber's filter removes a protected field, subsequent...

Name of the Vulnerable Software and Affected Versions Parse Server versions prior to 8.6.66 Parse Server versions prior to 9.7.0-alpha.10 Description Parse Server, an open source backend deployable on Node.js infrastructures, has an issue where the GraphQL API endpoint does not enforce the...

GHSA-W73W-G5XW-RWHF Parse Server has an MFA single-use token bypass via concurrent authData login requests

Impact An attacker who possesses a valid authentication provider token and a single MFA recovery code or SMS one-time password can create multiple authenticated sessions by sending concurrent login requests via the authData login endpoint. This defeats the single-use guarantee of MFA recovery cod...

Time-of-check Time-of-use (TOCTOU) Race Condition

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 Time-of-check Time-of-use TOCTOU Race Condition through the authData login process. An attacker can maintain multiple...

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 via the verifyPassword endpoint. An attacker can obtain sensitive authentication data, such as MFA TOTP...

GHSA-WP76-GG32-8258 Parse Server exposes auth data via verify password endpoint

Impact The verify password endpoint returns unsanitized authentication data, including MFA TOTP secrets, recovery codes, and OAuth access tokens. An attacker who knows a user's password can extract the MFA secret to generate valid MFA codes, defeating multi-factor authentication protection. Patch...

BIT-PARSE-2026-33627 Parse Server: Auth data exposed via /users/me endpoint

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.61 and 9.6.0, an authenticated user calling GET /users/me receives unsanitized auth data, including sensitive credentials such as MFA TOTP secrets and recovery codes. The...

BIT-PARSE-2026-33624 Parse Server: MFA recovery code single-use bypass via concurrent requests

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.60 and 9.6.0, an attacker who obtains a user's password and a single MFA recovery code can reuse that recovery code an unlimited number of times by sending concurrent logi...

BIT-PARSE-2026-33539 Parse Server: SQL injection via aggregate and distinct field names in PostgreSQL adapter

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.59 and 9.6.0, an attacker with master key access can execute arbitrary SQL statements on the PostgreSQL database by injecting SQL metacharacters into field name parameters...

BIT-PARSE-2026-33538 Parse Server: Denial of service via unindexed database query for unconfigured auth providers

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.58 and 9.6.0, an unauthenticated attacker can cause denial of service by sending authentication requests with arbitrary, unconfigured provider names. The server executes a...

BIT-PARSE-2026-33527 Parse Server: Session update endpoint allows overwriting server-generated session fields

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.57 and 9.6.0, an authenticated user can overwrite server-generated session fields such as expiresAt and createdWith when updating their own session via the REST API. This...
