CVE-2026-45799 Wire: skipGroup() missing negative-length check allows 10-byte payload to crash any Wire-decoding service

Wire provides gRPC and protocol buffers for Android, Kotlin, Swift, and Java. Prior to 6.3.0 and 7.0.0-alpha03, ByteArrayProtoReader32.skipGroup and ProtoReader.skipGroup in wire-runtime do not validate that a LENGTHDELIMITED field length is non-negative before skip, allowing a crafted protobuf...

CVE-2026-55407

Buffa is a pure-Rust Protocol Buffers implementation with first-class protobuf editions support. Prior to 0.8.0, the decodeunknownfield function in buffa's protobuf decoder allocated heap memory in proportion to untrusted input unknown fields in the serialized protobuf without enforcing an...

PYSEC-2026-3153 Null-dereference in Tensorflow

Impact When decoding a tensor from protobuf, TensorFlow might do a null-dereference if attributes of some mutable arguments to some operations are missing from the proto. This is guarded by a DCHECK: cc const auto attr = attrs.Findarg-s; DCHECKattr != nullptr; if attr-valuecase == AttrValue::kLis...

PYSEC-2026-3204 Reachable Assertion in Tensorflow

Impact When decoding a tensor from protobuf, a TensorFlow process can encounter cases where a CHECK assertion is invalidated based on user controlled arguments, if the tensors have an invalid dtype and 0 elements or an invalid shape. This allows attackers to cause denial of services in TensorFlow...

protobufjs: protobufjs: Arbitrary code execution due to unsafe expression generation from crafted protobuf descriptors

A flaw was found in protobufjs, a library used to compile protobuf definitions into JavaScript functions. A remote attacker could exploit this vulnerability by providing a crafted descriptor that includes a non-string default value for a bytes field. This could lead to the generation of an unsafe...

PYSEC-2026-1326 ESPHome vulnerable to denial-of-service via out-of-bounds check bypass in the API component

Summary An integer overflow in the API component's protobuf decoder allows denial-of-service attacks when API encryption is not used. Details The bounds check ptr + fieldlength end in components/api/proto.cpp can overflow when a malicious client sends a large fieldlength value. This affects all...

PYSEC-2026-1806 protobuf-python has a potential Denial of Service issue

Summary 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. Reporter: Alexis Challande, Trail of Bits...

PYSEC-2026-899 protobuf-cpp and protobuf-python have potential Denial of Service issue

Summary A message parsing and memory management vulnerability in ProtocolBuffer’s C++ and Python implementations can trigger an out of memory OOM failure when processing a specially crafted message, which could lead to a denial of service DoS on services using the libraries. Reporter: ClusterFuzz...
