Insecure Access Control

Vulnerability

Insecure access control functions as a systemic weakness within decentralized protocols, where insufficient authorization logic permits unauthorized entities to interact with sensitive smart contract functions. This failure typically manifests when administrative modifiers or permission checks are bypassed, granting external actors control over protocol parameters, treasury assets, or liquidity pools. Quantitative analysts identify these flaws as critical risk vectors that fundamentally compromise the integrity of onchain governance and automated execution.
