BIT-ZOOKEEPER-2026-59969 Apache ZooKeeper: Improper validation of certificate with host mismatch in FIPS mode

Apache ZooKeeper quorum TLS fails to enforce peer hostname verification in FIPS-mode deployments. When sslQuorum=true, zookeeper.fips-mode=true, ssl.quorum.hostnameVerification=true, and ssl.quorum.clientHostnameVerification=true are enabled, the Java SSLSocket quorum path accepts a CA-trusted pe...

AnyIO: TLSStream IDNA 2003 host name encoding enables potential TLS certificate spoofing

Impact Services using internationalized non-ASCII domain names are potentially vulnerable to TLS connections made from AnyIO's connecttcp or directly via TLSStream.wrap where the connection has through other means been hijacked and redirected to a malicious server. The attacker would obtain a...
