Last modified Jun 17, 2026

CVE-2019-0231 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Handling of the close_notify SSL/TLS message does not lead to a connection closure, leading the server to retain the socket opened and to have the client potentially receive clear text messages afterward. Mitigation: 2.0.20 users should migrate to 2.0.21, 2.1.0 users should migrate to 2.1.1. EPSS estimates a 2.20% chance of exploitation in the next 30 days.
