CVE-2022-42920
Apache Commons BCEL has a number of APIs that would normally only allow changing specific class characteristics.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.01%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Apache Commons BCEL has a number of APIs that would normally only allow changing specific class characteristics. However, due to an out-of-bounds writing issue, these APIs can be used to produce arbitrary bytecode. This could be abused in applications that pass attacker-controllable data to those APIs, giving the attacker more control over the resulting bytecode than otherwise expected. Update to Apache Commons BCEL 6.6.0.
