Cosmos EVM Flaw Exploited After Cosmos Labs Knew Every Blockchain Running It Was Vulnerable

By [email protected] (The Hacker News)

AI Summary

A critical balance-handling vulnerability (GHSA-7g4w-cg88-2cq2) in the shared Cosmos EVM module was exploited between August 20–25, 2026, draining funds from six separate blockchains, with affected versions below 0.6.2 or at or above an unspecified upper bound. Cosmos Labs reportedly was aware of the vulnerability before exploitation occurred, raising disclosure and coordination concerns across the multi-chain ecosystem. The absence of a CVE identifier, CVSS score, or weakness classification in the advisory complicates downstream patching and risk assessment.

Relevance score: 65.0/100
