CVE ID :CVE-2026-53430<\/p>\n
Published : June 15, 2026, 11:16 p.m. | 25\u00a0minutes ago<\/p>\n
Description :Improper Handling of Highly Compressed Data (Data Amplification) vulnerability in elixir-grpc grpc (GRPC.Compressor.Gzip, GRPC.Message modules) allows a denial of service via a gzip decompression bomb.<\/p>\n
This vulnerability is associated with program files lib\/grpc\/compressor\/gzip.ex, lib\/grpc\/message.ex and program routines ‘Elixir.GRPC.Compressor.Gzip’:decompress\/1, ‘Elixir.GRPC.Message’:from_data\/2.<\/p>\n
‘Elixir.GRPC.Compressor.Gzip’:decompress\/1 calls :zlib.gunzip\/1 directly on attacker-controlled bytes with no decompressed-size limit, ratio check, or incremental decoding. Because this module is the registered gzip GRPC.Compressor implementation, it is invoked automatically whenever an incoming gRPC frame carries the grpc-encoding: gzip header. :zlib.gunzip\/1 allocates the entire decompressed result as a single binary, so a small highly compressible payload (for example a few kilobytes of zeros, which gzip compresses at roughly 1000:1) expands to multiple gigabytes inside a single call. The max_receive_message_length limit is enforced only against the already-decompressed message, so it provides no protection. An unauthenticated remote peer can send a single crafted frame to exhaust the BEAM node’s heap and trigger an out-of-memory kill.<\/p>\n
This issue affects grpc: from 0.4.0 before 1.0.0.<\/p>\n
Severity: 8.7 | HIGH<\/p>\n
