These 64-bit block ciphers are vulnerable to the Sweet32 attack (CVE-2016-2183), which, over very long-lived TLS connections carrying large volumes of traffic, could allow an attacker to recover small amounts of plaintext. The issue is fixed in Kyverno 1.9.5 and 1.10.0.","published":"2026-09-01T12:17:11.220","modified":"2026-09-01T12:17:11.220","cvss":{"score":3.7,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/kyverno/kyverno/security/advisories/GHSA-hgv6-w7r3-w4qw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/kyverno-before-1.9.5-sweet32-medium-strength-cipher-suites"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-01T12:17:11.220"}}
