Security researcher Doyeon Park has publicly disclosed a zero-day vulnerability in Cosmos's consensus layer, CometBFT, which could lead to node stalling during block synchronization. The vulnerability has been rated with a CVSS score of 7.1, indicating high severity, although it does not allow for direct asset theft. The Cosmos ecosystem secures assets worth over $8 billion. Park adhered to the Coordinated Vulnerability Disclosure process to protect the ecosystem but opted for public disclosure after the vendor's lack of cooperation and decision-making issues. This disclosure aims to prompt necessary action to address the vulnerability.
