### Summary Insecure 3DES ciphers are used which may lead to exploitation of the [Sweet32 vulnerability](https://sweet32.info/). Specifically, the ciphers TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA (secp256r1) and TLS_RSA_WITH_3DES_EDE_CBC_SHA (rsa 2048) are allowed. See CVE-2016-2183. This is fixed in Kyverno v1.9.5 and v1.10.0 and no known users have been affected. ### Details The ciphers in affected versions can be read using the following command which uses :
