NewCVE-2026-26267 (opens in a new tab)How to fix?
Upgrade soroban-sdk-macros to version 22.0.10, 23.5.2, 25.1.1 or higher.
Overview
Affected versions of this package are vulnerable to Always-Incorrect Control Flow Implementation due to the #[contractimpl] macro generating calls to inherent functions instead of trait functions when names collide. An attacker can bypass critical security checks by invoking contract entry points that unintentionally call the inherent function, allowing unauthorized actions.
Workaround
This vulnerability can be mitigated by ensuring that no inherent associated function on the contract type shares a name with any function in the trait implementation, such as by renaming or removing the conflicting inherent function.
