SCA: security update for seroval (GHSA-f86p-h4j2-7qgj)

medium Tenable Self-Hosted Container Security Plugin ID 477782

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. From 1.6.0 until 1.6.11, the JavaScript-output APIs derive a typed array's constructor name
 from a property on the value that can be replaced by an own constructor property. When application code
 copies untrusted properties onto a typed array and then passes it to serialize, serializeAsync,
 crossSerialize, crossSerializeAsync, crossSerializeStream, Serializer, or compileJSON, the attacker-
 controlled name is written as executable JavaScript and can run in the page receiving the output. This
 issue is fixed in version 1.6.11. (CVE-2026-116583)

Solution

Update the seroval library and its related packages to version 1.6.11 or later.
