Prior to version 0.133.0, when model render generation is enabled, a logged-in user can achieve RCE by uploading a ZIP containing a file with a shell metacharacter in its name.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
