GHSA-GRP7-V8XH-RJ7H gRPC Erlang package vulnerable to Remote Code Execution with attacker-controlled gRPC payloads

Summary GRPC.Codec.Erlpack.decode/2 calls :erlang.binarytoterm/1 directly on the raw gRPC message body without the :safe option. Any unauthenticated peer that can reach a gRPC endpoint with Content-Type: application/grpc+erlpack can crash the entire BEAM node via atom table exhaustion or, if a...

gRPC Erlang package vulnerable to Remote Code Execution with attacker-controlled gRPC payloads

The vulnerability of the Erlpack codec library in the gRPC procedure call library for the Elixir programming language allows a perpetrator to execute arbitrary code or cause a service failure.

The vulnerability of the Erlpack codec in the gRPC procedure call library for the Elixir programming language involves shortcomings in the deserialization mechanism. Exploiting this vulnerability allows an attacker to execute arbitrary code or cause service failures...

CVE-2026-48853

Deserialization of Untrusted Data and Allocation of Resources Without Limits or Throttling vulnerabilities in elixir-grpc grpc allow unauthenticated attackers to crash the BEAM node via atom table exhaustion and, when a decoded term flows into a call site that invokes it, achieve remote code...

EEF-CVE-2026-48853 Remote code execution and denial of service via unsafe Erlang term deserialization in elixir-grpc/grpc

Summary Deserialization of Untrusted Data and Allocation of Resources Without Limits or Throttling vulnerabilities in elixir-grpc grpc allow unauthenticated attackers to crash the BEAM node via atom table exhaustion and, when a decoded term flows into a call site that invokes it, achieve remote...

CVE-2026-48853

CVE-2026-48853 affects the elixir-grpc/grpc stack where the Erlpack codec decodes gRPC payloads with :erlang.binary_to_term/1 without safety bounds. This leads to untrusted data deserialization, atom creation risk (atom table exhaustion) and potential remote code execution if a malicious term rea...
