CVE-2026-46385

A flaw was found in the Avro array and map decoding logic in Go Avro. The decoder failed to properly stop processing after encountering read errors while iterating over attacker-controlled block-count values, leading to excessive resource consumption. A remote unauthenticated attacker could explo...

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...

GHSA-W8J3-PQ8G-8M7W iskorotkov/avro: CPU Exhaustion in Decoder

CPU Exhaustion in Avro Decoder via Unbounded Block-Count Iteration Summary 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...
