CVE-2025-4565
Summary
Any project that uses Protobuf pure-Python backend to parse untrusted Protocol Buffers data containing an arbitrary number of recursive groups, recursive messages or a series of
SGROUPtags can be corrupted by exceeding the Python recursion limit.Reporter: Alexis Challande, Trail of Bits Ecosystem Security Team
ecosystem@trailofbits.com
Affected versions: This issue only affects the pure-Python implementation of protobuf-python backend. This is the implementation when
PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=pythonenvironment variable is set or the default when protobuf is used from Bazel or pure-Python PyPi wheels. CPython PyPi wheels do not use pure-Python by default.This is a Python variant of a previous issue affecting protobuf-java.
Severity
This is a potential Denial of Service. Parsing nested protobuf data creates unbounded recursions that can be abused by an attacker.
Proof of Concept
For reproduction details, please refer to the unit tests decoder_test.py and message_test
Remediation and Mitigation
A mitigation is available now. Please update to the latest available versions of the following packages:
