SCA: security update for immer (GHSA-33f9-j839-rf8h)

critical Tenable Self-Hosted Container Security Plugin ID 409244

Description

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

 - This affects the package immer before 9.0.6. A type confusion vulnerability can lead to a bypass of
 CVE-2020-28477 when the user-provided keys used in the path parameter are arrays. In particular, this
 bypass is possible because the condition (p === "__proto__" || p === "constructor") in applyPatches_
 returns false if p is ['__proto__'] (or ['constructor']). The === operator (strict equality operator)
 returns false if the operands have different type. (CVE-2021-23436)
