CVE-2026-28410Network attack vector

Locked-token reuse via incorrect vesting accounting

Published Mar 5, 2026 · Updated Mar 5, 2026

Incorrect vesting accounting in The Graph Protocol Contracts before 3.0.0 allows remote authenticated users to reuse withdrawn tokens. GraphTokenLockWallet's usedAmount check compares protocol use only with vestedAmount and ignores tokens already released and withdrawn. A vested beneficiary can withdraw vested tokens and then stake or delegate the same amount, leaving too little contract balance for revocation.
