CVE-2022-35411: Rpc.py Project Rpc.py

Critical severity, CVSS 9.8. EPSS: 45.7% chance of exploitation in the next 30 days.

rpc.py through 0.6.0 allows Remote Code Execution because an unpickle occurs when the "serializer: pickle" HTTP header is sent. In other words, although JSON (not Pickle) is the default data format, an unauthenticated client can cause the data to be processed with unpickle.

Affected products

• Rpc.py Project Rpc.py: from 0.4.2, up to and including 0.6.0
