CVE-2025-61684 is a high-severity vulnerability in quicly, an IETF QUIC protocol implementation used by the h2o project. The flaw stems from improper input validation (CWE-20) that allows a remote attacker to cause an assertion failure, crashing the process and resulting in a denial-of-service (DoS) condition. This vulnerability affects all versions of quicly prior to commit d9d3df6. Exploitation requires no authentication or user interaction and can be triggered remotely over the network. While no known exploits are currently observed in the wild, the CVSS score of 7.5 reflects the ease of exploitation and significant impact on availability. The issue was fixed in commit d9d3df6a8530a102b57d840e39b0311ce5c9e14e. European organizations using h2o’s quicly implementation in their infrastructure, especially those relying on QUIC for web or application traffic, should prioritize patching to prevent potential service disruptions. Countries with high adoption of modern web infrastructure and significant internet-facing services are most at risk.
