Hi,
The following vulnerability was published for protobuf.
CVE-2025-4565[0]:
| 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 SGROUP tags can
| be corrupted by exceeding the Python recursion limit. This can
| result in a Denial of service by crashing the application with a
| RecursionError. We recommend upgrading to version =>6.31.1 or beyond
