SCA: security update for seroval (GHSA-9wx9-5pv9-3349)

medium Tenable Self-Hosted Container Security Plugin ID 477783

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 1.0.0 and from 1.5.5 until 1.6.10, the JavaScript-output APIs serialize a RegExp
 source containing a less-than character without the escaping needed for an HTML script element. An
 application is affected when it builds regular expression syntax from untrusted input, serializes that
 RegExp through serialize, serializeAsync, crossSerialize, crossSerializeAsync, crossSerializeStream,
 Serializer, or compileJSON, and embeds the result in an HTML script element. The crafted source can
 terminate the element and execute script in the page received by another user. This issue is fixed in
 version 1.6.10. (CVE-2026-116582)

Solution

Update the seroval library and its related packages to version 1.0.0 or later.
