CVE-2026-0994 [HIGH] CWE-674 CVE-2026-0994: A denial-of-service (DoS) vulnerability exists in google.protobuf.json_format.ParseDict() in Python, 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 i

CVE-2024-7254 [HIGH] CWE-400 CVE-2024-7254: Any project that parses untrusted Protocol Buffers data containing an arbitrary number of nested gro 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 Protobuf Lite parser, or against Protobuf map fields, creates unbounded recursions t

CVE-2024-2410 [HIGH] CWE-416 CVE-2024-2410: The JsonToBinaryStream() function is part of the protocol buffers C++ implementation and is used to 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-2021-22570 [MEDIUM] CWE-476 CVE-2021-22570: Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, 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 upgrading to version 3.15.0 or greater.
