CVE-2026-106511
Last modified
CVE-2026-106511 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. MultiversX's multisig-improved (repository: mx-multisig-and-modules) reference implementation of their on-chain multisig smart contract system contains a vulnerability where a missing independent authorization check allows any account with the Proposer role to perform explicitly barred actions. This vulnerability allows the Proposer role to move funds alone, draining 100% of a contract's EGLD/ESDT balance in two transactions with zero signatures.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
