Uncontrolled Recursion

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 Uncontrolled Recursion via the requestComplexity.queryDepth configuration setting when processing WebSocket subscription...

Uncontrolled Recursion

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 Uncontrolled Recursion via the pre-validation transform pipeline. An attacker can cause the server process to become...

GHSA-9FJP-Q3C4-6W3J Parse Server has a query condition depth bypass via pre-validation transform pipeline

Impact An attacker can send an unauthenticated HTTP request with a deeply nested query containing logical operators to permanently hang the Parse Server process. The server becomes completely unresponsive and must be manually restarted. This is a bypass of the fix for CVE-2026-32944. Patches The...

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 watch parameter in LiveQuery subscriptions targeting protected fields. An attacker can infer...

GHSA-QPC3-FG4J-8HGM Parse Server has a protected field change detection oracle via LiveQuery watch parameter

Impact An attacker can subscribe to LiveQuery with a watch parameter targeting a protected field. Although the protected field value is properly stripped from event payloads, the presence or absence of update events reveals whether the protected field changed, creating a binary oracle. For boolea...

Incorrect Authorization

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 Incorrect Authorization in the LiveQuery WebSocket interface due to improper enforcement of pointer permissions. An attacker...

BIT-PARSE-2026-33163 Parse Server leaks protected fields via LiveQuery afterEvent trigger

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0 and 8.6.50, when a Parse.Cloud.afterLiveQueryEvent trigger is registered for a class, the LiveQuery server leaks protected fields and authData to all subscribers of that class...

BIT-PARSE-2026-33042 Parse Server affected by empty authData bypassing credential requirement on signup

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0 and 8.6.49, a user can sign up without providing credentials by sending an empty authData object, bypassing the username and password requirement. This allows the creation of...

BIT-PARSE-2026-32944 Parse Server crash via deeply nested query condition operators

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0 and 8.6.45, an unauthenticated attacker can crash the Parse Server process by sending a single request with deeply nested query condition operators. This terminates the server an...

BIT-PARSE-2026-32886 Parse Server's Cloud function dispatch crashes server via prototype chain traversal

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0 and 8.6.47, remote clients can crash the Parse Server process by calling a cloud function endpoint with a crafted function name that traverses the JavaScript prototype chain of a...
