CVE-2026-97031
Last modified
CVE-2026-97031 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Multiple ECH outer extension references are not permitted under RFC 9849; previously, a client could send a well-crafted packet that could trigger memory exhaustion in the server process by specifying multiple references. We now reject these as malformed and curb the memory amplification vector as a result.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
