String format specifiers based on user provided input are not properly validated, which could allow an attacker to execute arbitrary code.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
