Upgrade org.webjars.npm:seroval to version 1.6.11 or higher.
Overview
org.webjars.npm:seroval is a Stringify JS values
Affected versions of this package are vulnerable to Arbitrary Code Injection via the typed array serialization path in createTypedArrayNode and createBigIntTypedArrayNode, where the serializer uses value.constructor.name to write the constructor name after new in the generated output. An attacker who can supply a typed array with an own constructor property set to an object whose name is arbitrary code can inject that code into the serialized output, which is subsequently executed when deserialized.
