Technical Description
soroban-sdk is a Rust SDK for Soroban contracts. Prior to versions 22.0.10, 23.5.2, and 25.1.1, the `#[contractimpl]` macro contains a bug in how it wires up function calls. `#[contractimpl]` generates code that uses `MyContract::value()` style calls even when it's processing the trait version. This means if an inherent function is also defined with the same name, the inherent function gets called instead of the trait function. This means the Wasm-exported entry point silently calls the wrong function when two conditions are met simultaneously: First, an `impl Trait for MyContract` block is defined with one or more functions, with `#[contractimpl]` applied. Second, an `impl MyContract` block is defined with one or more identically named functions, without `#[contractimpl]` applied. If the trait version contains important security checks, such as verifying the caller is authorized, that the inherent version does not, those checks are bypassed. Anyone interacting with the contract throug
