SCA: security update for protobuf (GHSA-7gcm-g887-7qv7)

high Tenable Self-Hosted Container Security Plugin ID 437403

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A denial-of-service (DoS) vulnerability exists in google.protobuf.json_format.ParseDict() in Python, where
 the max_recursion_depth limit can be bypassed when parsing nested google.protobuf.Any messages. Due to
 missing recursion depth accounting inside the internal Any-handling logic, an attacker can supply deeply
 nested Any structures that bypass the intended recursion limit, eventually exhausting Python’s recursion
 stack and causing a RecursionError. (CVE-2026-0994)
