CVE-2022-29820

Information disclosure via unrestricted debugger-port binding

Published Apr 28, 2022 · Updated Aug 3, 2024

Information disclosure in JetBrains PyCharm before 2022.1 allows attackers on the internal network to access debugger data. The debugger listener binds to an unrestricted network interface instead of loopback, exposing its port to other internal hosts. A local user must start and interact with a debugging session; the documented consequence is limited to data disclosure.
