The latest version of utils-extend (1.0.8) is vulnerable to Prototype Pollution through the entry function(s) lib.extend. An attacker can supply a payload with Object.prototype setter to introduce or modify properties within the global prototype chain, causing denial of service (DoS) a the minimum consequence.

A prototype pollution in the lib.createUploader function of @rpldy/uploader v1.8.1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

A prototype pollution in the lib.deepMerge function of @zag-js/core v0.50.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

A prototype pollution in the lib.Logger function of eazy-logger v4.0.1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

A prototype pollution in the lib.requireFromString function of module-from-string v3.3.1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

A prototype pollution in the lib.mutateMergeDeep function of @tanstack/form-core v0.35.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

A prototype pollution in the lib.deep function of @ndhoule/defaults v2.0.1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

### Summary The better-auth `/api/auth/error` page was vulnerable to HTML injection, resulting in a reflected cross-site scripting (XSS) vulnerability. ### Details The value of `error` URL parameter was reflected as HTML on the error page: https://github.com/better-auth/better-auth/blob/05ada0b79dbcac93cc04ceb79b23ca598d07830c/packages/better-auth/src/api/routes/error.ts#L81 ### PoC https://demo.better-auth.com/api/auth/error?error=%3Cscript%3Ealert(1)%3C/script%3E  ### Impact An attacker who exploited this vulnerability by coercing a user to visit a specially-crafted URL could execute arbitrary JavaScript in the context of the user's browser. Because better-auth is a dependency of web applications, the impact of such a vulnerability is unknowable; it depends on the functionality of the application/site using better-auth. I have calculated the CVSS score assuming the hypothetical victim is an...
