Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.62%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Apache Olingo versions 4.0.0 to 4.6.0 provide the AbstractService class, which is public API, uses ObjectInputStream and doesn't check classes being deserialized. If an attacker can feed malicious metadata to the class, then it may result in running attacker's code in the worse case.
