SCA: security update for seroval (GHSA-jp82-f5mq-hwhp)

high Tenable Self-Hosted Container Security Plugin ID 473007

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. Prior to 1.6.3, deserializeTypedArray in fromJSON and fromCrossJSON trusts a deserialized
 source value as an ArrayBuffer and does not bound the serialized element count. An attacker can provide a
 small untrusted JSON object with a large length value, causing the array-like TypedArray constructor to
 synchronously allocate the selected number of elements and exhaust CPU or memory while starving the event
 loop. The offset check does not reject the crafted source because source.byteLength is undefined. DataView
 reaches a similar unchecked cast but throws rather than allocating, and the issue has no identified
 confidentiality or integrity impact. This issue is fixed in version 1.6.3. (CVE-2026-104845)

Solution

Update the seroval library and its related packages to version 1.6.3 or later.
