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 in the password reset mechanism. An attacker can gain unauthorized access to a user's account by intercepting a password reset token and submitting concurrent requests, potentially causing the attacker's password to be set instead of the legitimate user's.

Upgrade parse-server to version 8.6.48, 9.6.0-alpha.28 or higher.

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 Prototype Pollution in the deep copy mechanism. An attacker can inject unauthorized fields into class schemas and bypass security restrictions by exploiting prototype pollution in the deep copy process.

Upgrade parse-server to version 8.6.44, 9.6.0-alpha.20 or higher.

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 Improper Validation of Syntactic Correctness of Input in the LiveQuery subscription when an invalid regular expression pattern is provided. An attacker can cause the server process to terminate, resulting in denial of service for all connected clients by submitting a subscription request containing a malformed regular expression.

Upgrade parse-server to version 8.6.43, 9.6.0-alpha.19 or higher.

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 Improperly Controlled Modification of Dynamically-Determined Object Attributes via the POST /classes/_Session endpoint. An attacker can manipulate server-generated session fields such as sessionToken, expiresAt, and createdWith by supplying crafted values, potentially bypassing session expiration policies and setting predictable session tokens.

Upgrade parse-server to version 8.6.42, 9.6.0-alpha.17 or higher.

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 while processing of deeply nested query condition operators. An attacker can cause the server process to crash and deny service to all connected clients by sending a single crafted request.

Upgrade parse-server to version 8.6.45, 9.6.0-alpha.21 or higher.

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 Cross-site Scripting (XSS) via the file upload process. An attacker can execute arbitrary scripts in the user's browser by uploading files with specially crafted Content-Type headers or with XML-based file extensions that bypass the blocklist. This can result in the compromise of session tokens, user credentials, or other sensitive data accessible via the browser's local storage.

Workaround

This vulnerability can be mitigated by configuring the fileUpload.fileExtensions option to use an allowlist of only the file extensions required by the application.

Upgrade parse-server to version 8.6.41, 9.6.0-alpha.15 or higher.

Affected versions of this package are vulnerable to Missing Authentication for Critical Function in the createSubscriptions process. An attacker can execute unauthorized GraphQL operations, access schema introspection, and bypass query complexity limits by connecting to the WebSocket endpoint without valid credentials.

Upgrade parse-server to version 8.6.40, 9.6.0-alpha.14 or higher.

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 Function Call With Incorrect Order of Arguments in the OAuth2 authentication adapter when both appidField and appIds are configured. An attacker can bypass authentication restrictions or cause authentication failures by exploiting the improper validation of app IDs, which results in a malformed value being sent to the token introspection endpoint instead of the user's actual access token.

Affected versions of this package are vulnerable to Improper Neutralization of Special Elements in Data Query Logic in the findUsersWithAuthData() function of authentication data identifier. An attacker can gain unauthorized access to any user account by sending a specially crafted login request that manipulates the user identifier, causing the server to perform a pattern-matching query instead of an exact-match lookup and returning a valid session token for the targeted account.

Upgrade parse-server to version 8.6.38, 9.6.0-alpha.12 or higher.
