CVE-2026-97724

Summary

A prototype pollution vulnerability in Software Mansion React Native Worklets before 0.12.2 allows an attacker-controlled object containing a proto property to modify the prototype of an object created during serialization in clonePlainJSObject in packages/react-native-worklets/src/memory/serializable.native.ts. When affected data is subsequently processed by React Native Worklets, the malformed serialized object can cause the React Native application to crash. This can result in a remotely triggered denial of service in applications that pass attacker-controlled data through the affected serialization path. In applications where the attacker-controlled data is persisted, the denial of service may persist across application restarts or repeated attempts to access the affected content.

Weaknesses

  • CWE-1321: CWE-1321 Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')

Workarounds

Applications can recursively reject or remove prototype-sensitive properties such as "proto", "constructor", and "prototype" from untrusted objects before passing them to affected Worklets APIs.
