SCA: security update for seroval (GHSA-p6vx-979v-rg4c)

critical Tenable Self-Hosted Container Security Plugin ID 473021

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. From 0.12.0 until 1.6.2, fromJSON deserialization of a fulfilled Promise control node can
pass a plugin-produced callable-bearing thenable to a native Promise resolver. ECMAScript thenable
assimilation then invokes the callable unexpectedly, allowing attacker-controlled JSON to trigger code in
applications using plugin-capable Seroval releases. This path bypasses the Promise resolver type-confusion
remediation in version 1.5.3 for CVE-2026-59940 because the unexpected invocation occurs through native
Promise settlement after the referenced value is deserialized. This issue is fixed in version 1.6.2.
(CVE-2026-104846)

Solution

Update the seroval library and its related packages to version 1.6.2 or later.
