Scroll Emergency Upgrade Fixes Prover Vulnerability, States Vulnerability Was Not Exploited

2026-11-11 21:54

ChainThink report, November 11: According to an official announcement, Scroll has registered the repaired proof verifier for batch version 10 and confirmed that the bundle proof verifier vulnerability deployed on the Ethereum mainnet has not been exploited.

The vulnerability was reported on November 3 and resolved on November 10. According to the report, the flaw could have allowed old valid proofs to be reused with new public inputs, ultimately enabling the confirmation of arbitrary state roots and withdrawal roots.

Exploiting this vulnerability requires a privileged prover role or entry into forced batch mode after seven consecutive days without finalization.

Scroll states that forced mode has never been activated, and all 748 finalizations during the vulnerability window utilized normal proofs; verifiers from previous versions were unaffected.
