CVE-2026-44434: CWE-345: Insufficient Verification of Data Authenticity in h2o quiclyCVE-2026-44434
0

Quicly, the QUIC protocol implementation used in the H2O HTTP server, had a vulnerability allowing stateless reset injection due to insufficient verification of secret pattern slots. This flaw enabled an on-path attacker to reset QUIC connections by exploiting zero-initialized pattern slots treated as valid resets. The issue was fixed by a specific commit (dccf5d4). The vulnerability has a medium severity with a CVSS score of 5.3 and impacts availability without affecting confidentiality or integrity.
