DescriptionCVE.org

A security flaw has been discovered in alibaba-fusion next up to 1.27.34. This issue affects the function ConfigProvider.getContextProps of the file components/dialog/index.tsx of the component deepMerge. Performing a manipulation of the argument locale results in improperly controlled modification of object prototype attributes. The attack may be initiated remotely. The reported GitHub issue was closed automatically due to inactivity.

AnalysisAI

Prototype pollution in alibaba-fusion/next (all versions through 1.27.34) allows remote unauthenticated attackers to inject arbitrary properties into Object.prototype by supplying crafted values to the locale argument processed by the deepMerge function inside ConfigProvider.getContextProps within the Dialog component. The attack is network-reachable with no authentication or user interaction required per the CVSS 4.0 vector, though real-world exploitation depends on attacker-controlled data reaching the locale prop. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the target application uses alibaba-fusion/next at version 1.27.34 or earlier with the Dialog component rendered and ConfigProvider.getContextProps called, and that attacker-controlled data flows into the locale argument processed by deepMerge. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) characterizes this as remotely exploitable with no prerequisites, which is the maximum-exposure attack surface profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No vendor-released patch has been identified at time of analysis; the GitHub issue at https://github.com/alibaba-fusion/next/issues/5101 was closed automatically due to inactivity without a fix being merged or acknowledged. … Detailed patch versions, workarounds, and compensating controls in full report.
