Unmanned vehicles are increasingly becoming essential weapons of war. But with a potential conflict with China looming large, Taiwan is scrambling to build a domestic drone industry from scratch.

Due to a missing constraint in the rv32im circuit, any 3-register RISC-V instruction (including remu and divu) in risc0-zkvm 2.0.0, 2.0.1, and 2.0.2 are vulnerable to an attack by a malicious prover. The main idea for the attack is to confuse the RISC-V virtual machine into treating the value of the rs1 register as the same as the rs2 register due to a lack of constraints in the rv32im circuit. This vulnerability was reported by Christoph Hochrainer via our Hackenproof bug bounty. The fix for the circuit was implemented in [zirgen/pull/238](https://github.com/risc0/zirgen/pull/238), and the update to risc0 was implemented in [risc0/pull/3181](https://github.com/risc0/risc0/pull/3181). Impacted on-chain verifiers have already been disabled via the estop mechanism outlined in the [Verifier Management Design](https://github.com/risc0/risc0-ethereum/blob/release-2.0/contracts/version-management-design.md#base-verifier-implementations). ## Mitigation It is recommend all impacted users u...

### Summary The RedirectSlashes function in middleware/strip.go is vulnerable to host header injection which leads to open redirect. ### Details The RedirectSlashes method uses the Host header to construct the redirectURL at this line https://github.com/go-chi/chi/blob/v5.2.1/middleware/strip.go#L55 The Host header can be manipulated by a user to be any arbitrary host. This leads to open redirect when using the RedirectSlashes middleware ### PoC Create a simple server which uses the RedirectSlashes middleware ``` package main import ( "fmt" "net/http" "github.com/go-chi/chi/v5" "github.com/go-chi/chi/v5/middleware" // Import the middleware package ) func main() { // Create a new Chi router r := chi.NewRouter() // Use the built-in RedirectSlashes middleware r.Use(middleware.RedirectSlashes) // Use middleware.RedirectSlashes // Define a route handler r.Get("/", func(w http.ResponseWriter, r *http.Request) { // A simple response w.Write([]byte("Hello, World!")) }) ...
