CVE-2026-54451

A flaw was found in Elixir protobuf, a pure Elixir implementation of Google Protobuf. An attacker can craft protobuf messages with a self-referential or cyclic message type. When these messages are decoded by the Protobuf.Decoder component, specifically the valueforfield function, an unbounded...

CVE-2026-54451

Elixir protobuf is a pure Elixir implementation of Google Protobuf. From 0.8.0 until 0.16.1, services that decode attacker-controlled protobuf bytes with Protobuf.Decoder can be taken offline when the schema contains a self-referential or cyclic message type. In lib/protobuf/decoder.ex,...

Protobuf: Unbounded recursion depth in embedded-message decoding

Summary Unbounded recursion depth in Protobuf.Decoder Hex package protobuf, versions = 0.8.0, 0.16.1 lets an unauthenticated attacker crash any service that decodes untrusted protobuf messages whose schema contains a self-referential or cyclic message type. A small request body a few KB to a few ...
