Technical ContextAI · show details

This vulnerability is classified under CWE-212. An issue was discovered in the Chat functionality of the TeamViewer desktop application 14.3.4730 on Windows. (The vendor states that it was later fixed.) Upon login, every communication is saved within Windows main memory.
