CVE-2025-61730  (opens in a new tab)

How to fix?

Upgrade Minimos:latest logstash-9.1-env2yaml to version 9.1.9-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream logstash-9.1-env2yaml package and not the logstash-9.1-env2yaml package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

During the TLS 1.3 handshake if multiple messages are sent in records that span encryption level boundaries (for instance the Client Hello and Encrypted Extensions messages), the subsequent messages may be processed before the encryption level changes. This can cause some minor information disclosure if a network-local attacker can inject messages during the handshake.
