| शीर्षक | Node.js @tanstack/db 0.6.8 Prototype Pollution |
|---|
| विवरण | `@tanstack/db` is vulnerable to prototype pollution through public query APIs.
The root package entry exports `queryOnce`, `createCollection`, and `localOnlyCollectionOptions`. A caller can pass an alias containing prototype-pollution path segments to `select()`, such as `__proto__.tanstackPolluted`.
During query compilation, `src/query/compiler/select.ts` processes select aliases as dot-separated nested paths. The alias is split with `alias.split('.')`, and each segment is used to build nested objects in the query result. Dangerous segments such as `__proto__`, `constructor`, and `prototype` are not filtered. When the first segment is `__proto__`, the write cursor can resolve to `Object.prototype`, causing the next assignment to pollute the global object prototype. |
