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.
