Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache UIMA Java SDK (uimaj) versions before 3.5.0 deserialize Java-serialized CAS data without validation. An attacker who can send such data to the Vinci service or to applications using CasIOUtils may be able to execute arbitrary code remotely, and Vinci is not started by default. Upgrade to uimaj 3.5.0.
