From what I’ve read is not authentication bypass, it’s a RCE using certificates to deliver the payload. If a specific signature is found it runs the code that was sent in place of the signing public key. It also means that only someone who has the ability to generate that specific key signature could use the RCE.
There were some other bits that looked like they could have been placed to enable compromising other build systems in the future when they checked for xz support.
The biggest issue is that your corners are lifting from the bed during the print. Fixing this is usually a combination of making sure the bed is clean and adding a brim to increase adhesion. Maybe messing with temperature and cooling fan settings for the first few layers.
Second is things look a bit over extruded. This could just be due to the corner issue though so fix that before any other changes.
You may want to try hotter too if you haven’t yet. Printing faster can sometimes require a bit of extra heat and too low can cause a different kind of stringing.
The plastic and wire twist ties that come on cables would work too.
The expression syntax for the GNU find command is very powerful. I would expect that it is up to the task. If you don’t have the GNU find command with it’s extensions I could see how it’s would be difficult.
If 35° (or something close to it) is the slicer setting for overhang detection it likely changes the cooling/speed/flow settings. If that is the case you can set it to a lower detection value and maybe get better results or change the normal cooling/speed/flow to be closer so it isn’t as drastic of a change.
