Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Thrift (org.apache.thrift:libthrift, Java) versions before 0.23.0 do not properly validate that a TLS certificate matches the host in the Java TSSLTransportFactory. The source gives few details on how the attack would be carried out. Upgrade to libthrift 0.23.0, which fixes the issue.
