2026-11-10 04:52

TechFlow reported on November 10 that, according to The Defiant, Sigma Prime, the development team behind the Ethereum consensus client Lighthouse, has released security patch v8.3.3, urging all beacon node operators to upgrade as soon as possible.

This version is classified as a high-priority update for beacon nodes for both staked and non-staked users, and a low-priority update for validator clients. The patch does not introduce breaking changes; users upgrading from v8.2.x or earlier should refer to the v8.3.0 release notes.

Sigma Prime said it will provide a link to the security advisory after network operators have had time to upgrade.
