Security researcher Doyeon Park disclosed a CVSS 7.1 zero-day in Cosmos' CometBFT causing potential node freezes during sync; vendor resistance, downgrades, and disclosure led to April 21 reveal; validators should avoid restarts before patch. Abstract: Security researcher Doyeon Park disclosed a critical CVSS 7.1 zero-day vulnerability in Cosmos' CometBFT consensus layer that could cause nodes to freeze during block synchronization, potentially affecting networks securing over $8 billion in assets. The vulnerability cannot directly steal funds. Park pursued coordinated disclosure beginning Feb 22, but faced vendor resistance to public disclosure and issues with HackerOne. The vendor downgraded a related vulnerability (CVE-2025-24371) to informational on Mar 6, prompting Park to release a network-level proof-of-concept before public disclosure on Apr 21. The advisory recommends Cosmos validators avoid restarting nodes until patches are released; nodes already in consensus may continue but restart and resync could expose them to attacks by malicious peers, risking deadlock.
