| CVE-2026-0994 | Hig | 7.5 | >= 6.30.0rc1, < 6.33.5 | 6.33.5 | Jan 23, 2026 | 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 l | |
| CVE-2025-4565 | — | < 4.25.8 | 4.25.8 | Jun 16, 2025 | 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 s | ||
| CVE-2022-1941 | — | < 3.18.3 | 3.18.3 | Sep 22, 2022 | A parsing vulnerability for the MessageSet type in the ProtocolBuffers versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 3.21.5 for protobuf-cpp, and versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 4.21.5 for protobuf-python can | ||
| CVE-2021-22570 | — | < 3.15.0 | 3.15.0 | Jan 26, 2022 | Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file's name during generation of the resulting error message. Since the symbol is incorrectly parsed, the file is nullptr. We recommend |
