| Description | 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. |

Additional Advisory Data
Solutions
CNA: Upgrade React Native Worklets to version 0.12.2 or later. Version 0.12.2 includes the upstream fix for unsafe handling of "__proto__" properties during serialization and deserialization.
Workarounds
CNA: 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.
