@orpc/zod: Prototype injection in smart coercion
ghsa·2026-10-05
CVE-2026-103918 [MEDIUM] CWE-1321 @orpc/zod: Prototype injection in smart coercion
@orpc/zod: Prototype injection in smart coercion
## Summary
`ZodSmartCoercionPlugin` and `experimental_ZodSmartCoercionPlugin` mishandle object keys that name `Object.prototype` members. Both coerce request input before validation, so any client that can reach a procedure whose input schema contains an object or a record can:
1. replace the prototype of the coerced input object, and
2. make a request fail with an unhandled `TypeError` by sending a key such as `constructor`.
This is the same class of bug as GHSA-4h5r-cv8j-4456 in `@orpc/json-schema`, in a different package.
## This is not global prototype pollution
**The global `Object.prototype` is never modified.** No shared or global state is written, so other objects in the process, other requests, and other users are not affected

CVE-2026-64434 kernel: Bluetooth: L2CAP: Fix UAF in channel timeout by holding conn ref
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix UAF in channel timeout by holding conn ref
l2cap_chan_timeout() runs asynchronously and accesses chan->conn. If
the connection is torn down while the timer is running or pending,
chan->conn can be freed, leading to a use-after-free when the timer
worker attempts to lock conn->lock:
