SCA: security update for scim-patch (GHSA-9m6g-wc8r-q59c)

critical Tenable Self-Hosted Container Security Plugin ID 443783

Description

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

 - `scim-patch`, a library to perform SCIM patch, prior to version 0.9.1 performs prototype pollution when
 applying a SCIM PATCH operation whose `value` object contains a key like `"__proto__.someProp"`. After one
 such patch, `Object.prototype.someProp` is set process-wide, affecting every plain object in the Node
 process. Any service that calls `scimPatch()` on attacker-controlled JSON (i.e. any SCIM endpoint
 accepting `PATCH` from an external IdP) is exploitable on a stock Node runtime. Version 0.9.1 contains a
 patch. A workaround is available. Calling `Object.freeze(Object.prototype)` (and the same on
 `Array.prototype`, `Function.prototype`) at process startup neutralizes this class of bug — assignment to
 a frozen prototype becomes a silent no-op in sloppy mode or a `TypeError` in strict mode. Node's
 `--frozen-intrinsics` flag does this for built-ins automatically. (CVE-2026-48170)

Solution

Update the scim-patch library and its related packages to version 0.9.1 or later.
