SCA: security update for seroval (GHSA-3rxj-6cgf-8cfw)

high Tenable Cloud Security Plugin ID 436864

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - seroval facilitates JS value stringification, including complex structures beyond JSON.stringify
 capabilities. In versions 1.4.0 and below, improper input handling in the JSON deserialization component
 can lead to arbitrary JavaScript code execution. Exploitation is possible via overriding constant value
 and error deserialization, allowing indirect access to unsafe JS evaluation. At minimum, attackers need
 the ability to perform 4 separate requests on the same function, and partial knowledge of how the
 serialized data is used during later runtime processing. This vulnerability affects the fromJSON and
 fromCrossJSON functions in a client-to-server transmission scenario. This issue has been fixed in version
 1.4.0. (CVE-2026-23737)
