Polygon Discloses Critical Vulnerability

Asymmetric research disclosed a critical vulnerability in the Heimdall Polygon PoS validator software that could have been exploited to compromise over $2 billion worth of assets on the network’s bridge. The vulnerability was disclosed through Polygon’s Immunefi Bug Bounty program and has since been patched without exploitation. This vulnerability, which went unnoticed for five years, pertains to the bridging layers between Polygon’s Ethereum-based smart contracts and its PoS consensus layer. To exploit it, an attacker would need to inject false events into the StakeSync mechanism. Asymmetric Research recommends implementing time delays, transfer limits, and invariant checks on the native bridge as measures to diminish the chances of a attack.

ENS Labs is seeking input from the ENS DAO regarding its ongoing legal action against GoDaddy, Dynodot, and Manifold Finance for the recovery of the domain. The lawsuit initiated in September 2022 after GoDaddy transferred the domain to third-party registry Dynadot, who then re-auctioned it to Manifold Finance. Originally owned by early Ethereum contributor Virgil Griffith, the domain was allegedly falsely declared expired by GoDaddy. was a tool that enabled HTTP access to ENS domains, similarly to To date, ENS Labs has expended $750,000 on the lawsuit. Manifold Finance wants to relinquish the domain for $300,000.

The ENS DAO will vote on whether to accept the settlement and pay $300,000, propose a counteroffer, continue with the lawsuit, or dismiss the case. ENS Labs is also requesting reimbursement from the ENS DAO for the legal expenses it has incurred.
