pyarrow is vulnerable to Deserialization Of Untrusted Data. The vulnerability due to the Arrow IPC, Feather or Parquet data from untrusted sources as the library does not by default disable the PyExtensionType autoloading. This allows an attacker to create PyArrow-specific extension types which leads to arbitrary code execution from untrusted data sources.
