The problem:
A recent exploit with 7-Zip puts MO2 users at potential risk. Version 26.1, released in April 2026, is unaffected. The next release should update the 7z.dll file to at least 7-Zip version 26.1 to avoid this issue.
For now, people can manually patch this by installing/updating 7-Zip and copying the updated 7z.dll to MO2's dlls folder. I've patched this in my own installation, but an update to MO2 might revert it.
