GO-2026-5048 Denial of service via unbounded map allocations in github.com/iskorotkov/avro/v2 and github.com/hamba/avro/v2

The Avro map decoder accepts attacker-controlled block-element counts from the wire format and grows the destination map without enforcing an upper bound. A producer can declare an arbitrarily large map in one block, or chunked across many sub-limit blocks and exhaust process memory until the OOM...

PT-2026-65346

The Avro array and map decoders loop over an attacker-controlled block-count value without checking the underlying reader's error state inside the loop body. Reader.ReadBlockHeader returns the count as a Go int, which is 64-bit on amd64 and arm64 targets. A producer can declare a block of up to...
