Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The Python thrift package, versions before 0.24.0, does not properly validate that a server's certificate matches the host being connected to. An attacker able to intercept network traffic between a client and a Thrift server could potentially impersonate that server. Users should upgrade to thrift 0.24.0, which fixes the issue. The source gives few details beyond this.
