| CVE | Vendor / Product | Sev | Risk | CVSS | EPSS | KEV | Published | Description |
|---|---|---|---|---|---|---|---|---|
| CVE-2015-5237 | Hig | 0.58 | 8.8 | 0.05 | Sep 25, 2017 | protobuf allows remote authenticated attackers to cause a heap-based buffer overflow. | ||
| CVE-2024-2410 | Hig | 0.49 | 7.6 | 0.00 | May 3, 2024 | The JsonToBinaryStream() function is part of the protocol buffers C++ implementation and is used to parse JSON from a stream. If the input is broken up into separate chunks in a certain way, the parser will attempt to read bytes from a chunk that has already been freed. | ||
| CVE-2021-22569 | Hig | 0.49 | 7.5 | 0.02 | Jan 10, 2022 | An issue in protobuf-java allowed the interleaving of com.google.protobuf.UnknownFieldSet fields in such a way that would be processed out of order. A small malicious payload can occupy the parser for several minutes by creating large numbers of short-lived objects that cause… | ||
| CVE-2026-0994 | Hig | 0.42 | 7.5 | 0.01 | 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… | ||
| CVE-2024-7254 | Hig | 0.42 | 7.5 | 0.03 | Sep 19, 2024 | Any project that parses untrusted Protocol Buffers data containing an arbitrary number of nested groups / series of SGROUP tags can corrupted by exceeding the stack limit i.e. StackOverflow. Parsing nested groups as unknown fields with DiscardUnknownFieldsParser or Java… | ||
| CVE-2022-3510 | Hig | 0.42 | 7.5 | 0.00 | Dec 12, 2022 | A parsing issue similar to CVE-2022-3171, but with Message-Type Extensions in protobuf-java core and lite versions prior to 3.21.7, 3.20.3, 3.19.6 and 3.16.3 can lead to a denial of service attack. Inputs containing multiple instances of non-repeated embedded messages with… | ||
| CVE-2022-3509 | Hig | 0.42 | 7.5 | 0.01 | Dec 12, 2022 | A parsing issue similar to CVE-2022-3171, but with textformat in protobuf-java core and lite versions prior to 3.21.7, 3.20.3, 3.19.6 and 3.16.3 can lead to a denial of service attack. Inputs containing multiple instances of non-repeated embedded messages with repeated or… | ||
| CVE-2021-22570 | Med | 0.35 | 6.5 | 0.03 | 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… | ||
| CVE-2022-3171 | Med | 0.21 | 4.3 | 0.01 | Oct 12, 2022 | A parsing issue with binary data in protobuf-java core and lite versions prior to 3.21.7, 3.20.3, 3.19.6 and 3.16.3 can lead to a denial of service attack. Inputs containing multiple instances of non-repeated embedded messages with repeated or unknown fields causes objects to be… |
