CVE-2025-25500

An issue in CosmWasm prior to v2.2.0 allows attackers to bypass capability restrictions in blockchains by exploiting a lack of runtime capability validation. This allows attackers to deploy a contract without capability enforcement, and execute unauthorized actions on the blockchain...

Denial Of Service (DoS)

github.com/CosmWasm/wasmvm is vulnerable to a Denial-of-Service DoS. The vulnerability is due to a bug affecting both permissioned and permissionless chains due to its ability to be reliably triggered using a malicious contract, potentially causing a chain crash...

Cosmos: Attacker can use any non-enabled capability

The Capabilites implementation in CosmWasm contracts was found to have a vulnerability. Even if the executing chain did not allow a specific capability, a CosmWasm contract could still execute actions that required that capability. This was due to a naive implementation of capabilities and...

GO-2024-3101 Excessive number of function parameters in compiled Wasm in github.com/CosmWasm/wasmvm

A specifically crafted Wasm file can cause the VM to consume excessive amounts of memory when compiling a contract. This can lead to high memory usage, slowdowns, potentially a crash and can poison a lock in the VM, preventing any further interaction with contracts...
