SCA: security update for seroval (GHSA-7rv5-mrxv-xcr9)

high Tenable Cloud Security Plugin ID 477776

Description

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

 - Seroval facilitates JavaScript value stringification, including complex structures beyond JSON.stringify
 capabilities. Prior to 1.6.8, fromJSON rebuilds an AsyncIteratorFactoryInstance by calling
 source.on(listener) without requiring source to be a genuine internal stream. With untrusted Seroval input
 and an application plugin that returns a callable value or an object exposing an on method, a crafted node
 can reuse an identifier so the deserializer invokes the plugin-produced value. This is an incomplete-fix
 variant of CVE-2026-59940. The resulting confidentiality, integrity, or availability impact depends on the
 behavior exposed by the application plugin. This issue is fixed in version 1.6.8. (CVE-2026-116580)

Solution

Update the seroval library and its related packages to version 1.6.8 or later.
