CVE-2022-29072: 7-Zip

High severity, CVSS 7.8. EPSS: 1.5% chance of exploitation in the next 30 days.

7-Zip through 21.07 on Windows allows privilege escalation and command execution when a file with the .7z extension is dragged to the Help>Contents area. This is caused by misconfiguration of 7z.dll and a heap overflow. The command runs in a child process under the 7zFM.exe process. NOTE: multiple third parties have reported that no privilege escalation can occur
