CVE-2026-26267 describes a bug in the soroban-sdk Rust SDK, specifically within the #[contractimpl] macro, affecting stellar rs_soroban_sdk versions prior to 22.0.10, 23.5.2, and 25.1.1. This flaw causes the macro to incorrectly call an inherent function instead of a trait function if they share the same name, potentially bypassing critical security checks in smart contracts. With a CVSS score of 7.5 (HIGH), this vulnerability has a network attack vector, low attack complexity, and can lead to high integrity impact by allowing unauthorized actions. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
