CVE-2026-46385

iskorotkov/avro is a fast Go Avro codec. Prior to 2.33.0, the Avro array and map decoders looped 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 ...

CVE-2026-46384

iskorotkov/avro is a fast Go Avro codec. Prior to 2.33.0, several Avro decoder paths read attacker-controlled 64-bit values from the wire format and either narrowed them to platform-sized int before bounds-checking, or summed them with overflow-prone signed-int arithmetic. On 32-bit targets...

CVE-2026-46385

Summary (CVE-2026-46385) iskorotkov/avro’s Go Avro decoder can trigger remote, unauthenticated CPU exhaustion by looping up to math.MaxInt64 iterations when decoding large attacker-controlled block counts, because inner loops did not check the reader’s error state after each decode. Affected: git...
