CVE-2025-62374 in Parse-SDK-JS
Summary
by MITRE • 10/14/2025
Parse Javascript SDK provides access to the powerful Parse Server backend from your JavaScript app. Prior to 7.0.0, injection of malicious payload allows attacker to remotely execute arbitrary code. ParseObject.fromJSON, ParseObject.pin, ParseObject.registerSubclass, ObjectStateMutations (internal), and encode/decode (internal) are affected. This vulnerability is fixed in 7.0.0.

The vulnerability identified as CVE-2025-62374 represents a critical remote code execution flaw within the Parse JavaScript SDK that affects versions prior to 7.0.0. This vulnerability stems from insufficient input validation and sanitization mechanisms within the SDK's core parsing functions, creating a pathway for malicious actors to inject arbitrary code into applications that utilize the Parse Server backend. The affected components include ParseObject.fromJSON, ParseObject.pin, ParseObject.registerSubclass, ObjectStateMutations, and internal encode/decode functions, which collectively form the foundation of data processing and state management within the SDK. The vulnerability operates at the intersection of multiple security domains including data serialization, object manipulation, and remote code execution vectors.
The technical exploitation of this vulnerability occurs through careful crafting of malicious JSON payloads that can be processed by the affected ParseObject methods. When these methods receive untrusted input, particularly through fromJSON operations, the SDK fails to properly validate or sanitize the incoming data structure. This allows attackers to inject malicious code that gets executed within the context of the JavaScript application. The vulnerability manifests as a code injection attack pattern that can be categorized under CWE-94, which specifically addresses "Improper Control of Generation of Code ('Code Injection')" and aligns with ATT&CK technique T1059.007 for "Command and Scripting Interpreter: JavaScript." The internal nature of some affected functions like ObjectStateMutations and encode/decode operations makes this vulnerability particularly dangerous as it can be triggered through seemingly legitimate data processing operations.
The operational impact of CVE-2025-62374 extends beyond simple remote code execution to encompass complete system compromise of applications utilizing vulnerable Parse JavaScript SDK versions. Attackers can leverage this vulnerability to execute arbitrary commands on affected systems, potentially leading to data exfiltration, privilege escalation, and full system takeover. Applications that rely heavily on Parse Server for backend operations, including mobile applications, web applications, and hybrid systems, become vulnerable to sophisticated attacks. The vulnerability affects the fundamental data handling mechanisms of the SDK, meaning that any application using these functions for data synchronization, object persistence, or state management could be compromised. This creates a widespread risk across the Parse ecosystem, as the affected functions are commonly used throughout various application architectures and development workflows.
Mitigation strategies for CVE-2025-62374 center exclusively on upgrading to Parse JavaScript SDK version 7.0.0 or later, which contains the necessary security patches and input validation improvements. Organizations should conduct immediate inventory assessments to identify all applications using vulnerable SDK versions and prioritize remediation efforts accordingly. Additional defensive measures include implementing strict input validation at application level, employing web application firewalls to monitor for suspicious JSON payloads, and conducting regular security audits of data processing functions. The vulnerability serves as a reminder of the critical importance of keeping third-party libraries updated and implementing proper security controls around data serialization and deserialization operations. Security teams should also consider implementing runtime monitoring to detect anomalous execution patterns that might indicate exploitation attempts, particularly focusing on JavaScript execution contexts where the vulnerability could be triggered through legitimate application workflows.
