Vulnerability Title
scimPatch vulnerable to prototype pollution via unfiltered keys in patch
Vulnerability Description
`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.

Vulnerability Title
Thomas Poignant SCIM-PATCH 输入验证错误漏洞
Vulnerability Description
Thomas Poignant SCIM-PATCH是Thomas Poignant个人开发者开源的一款处理身份管理协议补丁操作的服务器端工具。 Thomas Poignant SCIM-PATCH 0.9.1之前版本存在输入验证错误漏洞,该漏洞源于应用SCIM PATCH操作时,value对象包含类似"__proto__.someProp"的键导致原型污染,可能影响Node进程中所有普通对象。
