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."}], "metrics": [{"cvssV4_0": {"Automatable": "NOT_DEFINED", "Recovery": "USER", "Safety": "NOT_DEFINED", "attackComplexity": "LOW", "attackRequirements": "NONE", "attackVector": "NETWORK", "baseScore": 5.3, "baseSeverity": "MEDIUM", "privilegesRequired": "NONE", "providerUrgency": "NOT_DEFINED", "subAvailabilityImpact": "NONE", "subConfidentialityImpact": "NONE", "subIntegrityImpact": "NONE", "userInteraction": "PASSIVE", "valueDensity": "DIFFUSE", "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/R:U/V:D/RE:L", "version": "4.0", "vulnAvailabilityImpact": "LOW", "vulnConfidentialityImpact": "NONE", "vulnIntegrityImpact": "NONE", "vulnerabilityResponseEffort": "LOW"}, "format": "CVSS", "scenarios": [{"lang": "en", "value": "GENERAL"}]}, {"cvssV3_1": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "LOW", "baseScore": 4.3, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L", "version": "3.1"}, "format": "CVSS", "scenarios": [{"lang": "en", "value": "GENERAL"}]}], "problemTypes": [{"descriptions": [{"cweId": "CWE-1321", "description": "CWE-1321 Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')", "lang": "en", "type": "CWE"}]}], "providerMetadata": {"orgId": "8254265b-2729-46b6-b9e3-3dfca2d5bfca", "shortName": "mitre", "dateUpdated": "2026-09-25T02:11:41.014Z"}, "references": [{"url": "https://github.com/software-mansion/react-native-reanimated/issues/10436"}, {"url": "https://github.com/software-mansion/react-native-reanimated/pull/10451"}, {"url": "https://github.com/software-mansion/react-native-reanimated/pull/10462"}, {"url": "https://github.com/software-mansion/react-native-reanimated/releases/tag/worklets-0.12.2"}, {"url": "https://docs.swmansion.com/react-native-reanimated/"}], "solutions": [{"lang": "en", "supportingMedia": [{"base64": false, "type": "text/html", "value": "Upgrade React Native Worklets to version 0.12.2 or later.
