SCA: security update for devalue (GHSA-77vg-94rm-hx3p)

high Tenable Self-Hosted Container Security Plugin ID 442847

Description

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

 - Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't
 sufficient for the job. From version 5.6.3 to before version 5.8.1, devalue.parse could, due to quirks in
 some JavaScript engines, be convinced to allocate much more memory than was needed when deserializing
 sparse arrays, leading to excessive memory consumption. This issue has been patched in version 5.8.1.
 (CVE-2026-42570)

Solution

Update the devalue library and its related packages to version 5.8.1 or later.
