Recommendation: Monitor — no exploitation signal at the moment.

estree-util-value-to-estree converts a JavaScript value to an ESTree expression. When generating an ESTree from a value with a property named __proto__, valueToEstree would generate an object that specifies a prototype instead. This vulnerability is fixed in 3.3.3.
