The realistic ceiling is \"indefinite until the worker is killed externally\" — a single hostile payload pins a CPU core until the process is OOM-killed, deadline-cancelled, or terminated. Remote, unauthenticated denial-of-service.\n\nThe fix exits the loop on the first inner-decode error. It does not bound the loop length itself; for full coverage on untrusted inputs, also configure `Config.MaxSliceAllocSize` and `Config.MaxMapAllocSize` (the latter introduced in `v2.33.0`).\n\n## Description\n\nAvro arrays and maps are encoded as one or more blocks; each block declares an element count followed by that many encoded elements. The decoder reads the block count as a zigzag-encoded `long`, then iterates that many times calling an inner decoder.\n\nThree iteration sites trusted the block count without checking the reader's accumulated error state between iterations:\n\n- `codec_skip.go` `sliceSkipDecoder.Decode` — skip helper for arrays.\n- `codec_skip.go` `mapSkipDecoder.Decode` — skip helper for maps.\n- `reader_generic.go` `Reader.ReadArrayCB` and `Reader.ReadMapCB` — callback-based decoders used by generic and unmarshaling code paths.\n\nBecause the inner `Decode(nil, r)` call is a no-op when `r` has already errored (it returns immediately without consuming bytes), the loop would run to completion even after the first iteration's EOF. On `amd64` / `arm64`, `Reader.ReadBlockHeader` returns the count as `int` (= `int64`), so the loop bound is whatever the wire payload specified, up to `math.MaxInt64`. A modest 200-million-count payload (well under 2³¹) already burns several seconds; a `math.MaxInt − 2` payload (the value used in the regression test `TestDecoder_ArrayMultiBlockExceedsMaxInt` from PR #9) effectively pins the goroutine until external kill.\n\nThis overlaps with [`GHSA-mc57-h6j3-3hmv`](https://github.com/iskorotkov/avro/security/advisories/GHSA-mc57-h6j3-3hmv): the same large-block-count payload that drives the unbounded loop here also drives the cumulative-arithmetic overflow there (cross-platform), and on a 32-bit target additionally triggers the union-index / byte-slice narrowing.\n\n## Affected components\n\n| File | Function | PR | Fix commit |\n|------|----------|----|------------|\n| `codec_skip.go` | `sliceSkipDecoder.Decode` | — | [`b124caa`](https://github.com/iskorotkov/avro/commit/b124caa58a821f68f100d86f045f9753b88881e8) |\n| `codec_skip.go` | `mapSkipDecoder.Decode` | — | [`b124caa`](https://github.com/iskorotkov/avro/commit/b124caa58a821f68f100d86f045f9753b88881e8) |\n| `reader_generic.go` | `Reader.ReadArrayCB` | [#4](https://github.com/iskorotkov/avro/pull/4) | [`2ce4242`](https://github.com/iskorotkov/avro/commit/2ce4242e6095d93470ab3b37ed6082b0596f325c) |\n| `reader_generic.go` | `Reader.ReadMapCB` | [#4](https://github.com/iskorotkov/avro/pull/4) | [`2ce4242`](https://github.com/iskorotkov/avro/commit/2ce4242e6095d93470ab3b37ed6082b0596f325c) |\n\nThese are the audited and patched sites. Any other code path that iterates over an attacker-controlled count while calling a `Reader`-style decoder is structurally susceptible to the same pattern; reviewers of consumer code should grep for `for range l` / `for i := 0; i \u003c int(l); i++` near `Reader` method calls and confirm an in-loop error check.\n\n## Technical details\n\n**Vulnerable pattern:**\n\n```go\nfor range l {\n    d.decoder.Decode(nil, r)\n    // r.Error may have been set by Decode; loop continues regardless.\n}\n```\n\nAfter `r.Error != nil`, subsequent `Decode` calls short-circuit and return without consuming bytes or doing useful work, but the loop control variable still runs to `l`. With `l = math.MaxInt64`, the loop body executes ~9.2 × 10¹⁸ times — effectively infinite for any realistic timeout.\n\n**Fixed pattern** ([`b124caa`](https://github.com/iskorotkov/avro/commit/b124caa58a821f68f100d86f045f9753b88881e8), [`2ce4242`](https://github.com/iskorotkov/avro/commit/2ce4242e6095d93470ab3b37ed6082b0596f325c)):\n\n```go\nfor range l {\n    d.decoder.Decode(nil, r)\n    if r.Error != nil {\n        break\n    }\n}\n```\n\nThe fix terminates the loop on the first inner error. It does **not** bound `l` itself — a well-formed payload that actually contains `N` encoded `null` elements still iterates `N` times. The `MaxSliceAllocSize` / `MaxMapAllocSize` caps are the policy-level bound on that case (see Mitigation).\n\n## Fixed behavior\n\nThe reader's accumulated error is checked after every inner `Decode` in the four affected loops. Decoder errors now surface in O(1) iterations instead of O(blockCount) when the underlying read fails mid-stream.\n\n## Affected versions\n\n- `github.com/hamba/avro/v2` — all versions up to and including `v2.31.0` (repository is read-only upstream).\n- `github.com/iskorotkov/avro/v2` — all versions prior to `v2.33.0`.\n\n## Fixed versions\n\n`github.com/iskorotkov/avro/v2` `v2.33.0` and later. There is no upstream fix for `github.com/hamba/avro/v2` — module path is archived. Migrate to the fork as described under Mitigation.\n\n## Mitigation\n\nMigrate from `github.com/hamba/avro/v2` to `github.com/iskorotkov/avro/v2 \u003e= v2.33.0`. Replace the import path and run `go mod tidy`:\n\n```bash\ngo get github.com/iskorotkov/avro/v2@latest\n```\n\nOr, for consumers that prefer the original import path, a `replace` directive in `go.mod`:\n\n```\nreplace github.com/hamba/avro/v2 =\u003e github.com/iskorotkov/avro/v2 v2.33.0\n```\n\n`replace` is honoured only for the **main** module of a build — transitive consumers must add their own `replace`, or migrate the import path directly.\n\nThe error-propagation fix runs on the existing decode path and requires no configuration.\n\nFor defense-in-depth against well-formed but oversized payloads (where the fix above does not help, because no error fires), set explicit allocation caps:\n\n```go\ncfg := avro.Config{\n    MaxByteSliceSize:  102_400,\n    MaxSliceAllocSize: 10_000,\n    MaxMapAllocSize:   10_000,\n}.Freeze()\n\ndecoder := cfg.NewDecoder(schema, reader)\n```\n\n`MaxMapAllocSize` is new in `v2.33.0` and opt-in (default zero, which leaves the previous unbounded behavior). Without setting it, a producer that ships a `math.MaxInt64`-count block still consumes the corresponding memory and CPU; see [`GHSA-mx64-mj3q-7prj`](https://github.com/iskorotkov/avro/security/advisories/GHSA-mx64-mj3q-7prj) for the cumulative-allocation enforcement details.\n\nIf you cannot upgrade immediately, the structural workarounds are application-level: per-request decode timeouts, isolated decoder workers under CPU quotas, and rejection of payloads whose advertised block count exceeds a known sane bound for your schema.\n\n## Proof-of-concept input\n\nA minimal payload that triggers the bug for an array of `int`:\n\n```\nzigzag-encoded long: math.MaxInt64   (block element count)\nEOF                                  (no further bytes)\n```\n\nThe decoder reads the block-count header, enters the loop, fails to read the first element (EOF), records the error, and then iterates `math.MaxInt64 − 1` further times calling the inner decoder as a no-op. Wall-clock cost on commodity hardware: indefinite — the goroutine pins one CPU core until the process is OOM-killed, deadline-cancelled, or terminated externally. The classic *\"a few seconds per request\"* characterisation applies only to small-but-still-pathological block counts in the 10⁸–10⁹ range (e.g. `200_999_000` in `TestDecoder_SkipArrayEOF`); the architectural ceiling is `math.MaxInt64`.\n\nA negative block count (`-N`) is also legal in Avro (signals an N-element block with an explicit byte length); the same iteration pattern applies once the count is negated.\n\n## References\n\n- Fix PR: [iskorotkov/avro#4](https://github.com/iskorotkov/avro/pull/4) (callback path)\n- Fix commits: [`b124caa`](https://github.com/iskorotkov/avro/commit/b124caa58a821f68f100d86f045f9753b88881e8) (skip helpers), [`2ce4242`](https://github.com/iskorotkov/avro/commit/2ce4242e6095d93470ab3b37ed6082b0596f325c) (callback path)\n- Release: [`v2.33.0`](https://github.com/iskorotkov/avro/releases/tag/v2.33.0)\n- Security policy: [`SECURITY.md`](https://github.com/iskorotkov/avro/blob/main/SECURITY.md)\n- Related advisories on this fork: [`GHSA-mc57-h6j3-3hmv`](https://github.com/iskorotkov/avro/security/advisories/GHSA-mc57-h6j3-3hmv) (integer overflow — same large-block-count payload also triggers cumulative-arithmetic overflow there), [`GHSA-mx64-mj3q-7prj`](https://github.com/iskorotkov/avro/security/advisories/GHSA-mx64-mj3q-7prj) (unbounded map allocation — the policy-level bound on well-formed huge inputs)\n- Cross-module precedent on `hamba/avro`: [`GO-2023-1930`](https://pkg.go.dev/vuln/GO-2023-1930) / `CVE-2023-37475` / `GHSA-9x44-9pgq-cf45`\n- Upstream (read-only): [`hamba/avro`](https://github.com/hamba/avro)\n\n## Credits\n\n- **Discovery and fixes** (commits `b124caa` skip helpers and `2ce4242` callback path, PR #4): Daniel Błażewicz ([@klajok](https://github.com/klajok))\n- **Release authorship**: Ivan Korotkov ([@iskorotkov](https://github.com/iskorotkov))\n\n## Timeline\n\n- **2026-04-28** — Skip-decoder fix (`b124caa`) merged.\n- **2026-04-30** — Callback-decoder fix (PR #4, `2ce4242`) merged.\n- **2026-05-06** — `v2.33.0` tagged and released.\n- **2026-05-11** — Advisory published.\n- **2026-05-15** — Advisory revised.","status":"published","published":"2026-05-18T16:33:43Z","modified":"2026-06-09T10:32:34Z","cvss":[{"version":"4.0","score":8.7,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","level":"high"},{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"cwes":["CWE-400","CWE-835","CWE-1284"],"updated_at":"2026-11-02T14:40:23.739691Z"}],"nvd":[{"id":"CVE-2026-46385","description":"iskorotkov/avro is a fast Go Avro codec.

The realistic ceiling is \"indefinite until the worker is killed externally\" — a single hostile payload pins a CPU core until the process is OOM-killed, deadline-cancelled, or terminated. Remote, unauthenticated denial-of-service.\n\nThe fix exits the loop on the first inner-decode error. It does not bound the loop length itself; for full coverage on untrusted inputs, also configure `Config.MaxSliceAllocSize` and `Config.MaxMapAllocSize` (the latter introduced in `v2.33.0`).\n\n## Description\n\nAvro arrays and maps are encoded as one or more blocks; each block declares an element count followed by that many encoded elements. The decoder reads the block count as a zigzag-encoded `long`, then iterates that many times calling an inner decoder.\n\nThree iteration sites trusted the block count without checking the reader's accumulated error state between iterations:\n\n- `codec_skip.go` `sliceSkipDecoder.Decode` — skip helper for arrays.\n- `codec_skip.go` `mapSkipDecoder.Decode` — skip helper for maps.\n- `reader_generic.go` `Reader.ReadArrayCB` and `Reader.ReadMapCB` — callback-based decoders used by generic and unmarshaling code paths.\n\nBecause the inner `Decode(nil, r)` call is a no-op when `r` has already errored (it returns immediately without consuming bytes), the loop would run to completion even after the first iteration's EOF. On `amd64` / `arm64`, `Reader.ReadBlockHeader` returns the count as `int` (= `int64`), so the loop bound is whatever the wire payload specified, up to `math.MaxInt64`. A modest 200-million-count payload (well under 2³¹) already burns several seconds; a `math.MaxInt − 2` payload (the value used in the regression test `TestDecoder_ArrayMultiBlockExceedsMaxInt` from PR #9) effectively pins the goroutine until external kill.\n\nThis overlaps with [`GHSA-mc57-h6j3-3hmv`](https://github.com/iskorotkov/avro/security/advisories/GHSA-mc57-h6j3-3hmv): the same large-block-count payload that drives the unbounded loop here also drives the cumulative-arithmetic overflow there (cross-platform), and on a 32-bit target additionally triggers the union-index / byte-slice narrowing.\n\n## Affected components\n\n| File | Function | PR | Fix commit |\n|------|----------|----|------------|\n| `codec_skip.go` | `sliceSkipDecoder.Decode` | — | [`b124caa`](https://github.com/iskorotkov/avro/commit/b124caa58a821f68f100d86f045f9753b88881e8) |\n| `codec_skip.go` | `mapSkipDecoder.Decode` | — | [`b124caa`](https://github.com/iskorotkov/avro/commit/b124caa58a821f68f100d86f045f9753b88881e8) |\n| `reader_generic.go` | `Reader.ReadArrayCB` | [#4](https://github.com/iskorotkov/avro/pull/4) | [`2ce4242`](https://github.com/iskorotkov/avro/commit/2ce4242e6095d93470ab3b37ed6082b0596f325c) |\n| `reader_generic.go` | `Reader.ReadMapCB` | [#4](https://github.com/iskorotkov/avro/pull/4) | [`2ce4242`](https://github.com/iskorotkov/avro/commit/2ce4242e6095d93470ab3b37ed6082b0596f325c) |\n\nThese are the audited and patched sites. Any other code path that iterates over an attacker-controlled count while calling a `Reader`-style decoder is structurally susceptible to the same pattern; reviewers of consumer code should grep for `for range l` / `for i := 0; i \u003c int(l); i++` near `Reader` method calls and confirm an in-loop error check.\n\n## Technical details\n\n**Vulnerable pattern:**\n\n```go\nfor range l {\n    d.decoder.Decode(nil, r)\n    // r.Error may have been set by Decode; loop continues regardless.\n}\n```\n\nAfter `r.Error != nil`, subsequent `Decode` calls short-circuit and return without consuming bytes or doing useful work, but the loop control variable still runs to `l`. With `l = math.MaxInt64`, the loop body executes ~9.2 × 10¹⁸ times — effectively infinite for any realistic timeout.\n\n**Fixed pattern** ([`b124caa`](https://github.com/iskorotkov/avro/commit/b124caa58a821f68f100d86f045f9753b88881e8), [`2ce4242`](https://github.com/iskorotkov/avro/commit/2ce4242e6095d93470ab3b37ed6082b0596f325c)):\n\n```go\nfor range l {\n    d.decoder.Decode(nil, r)\n    if r.Error != nil {\n        break\n    }\n}\n```\n\nThe fix terminates the loop on the first inner error. It does **not** bound `l` itself — a well-formed payload that actually contains `N` encoded `null` elements still iterates `N` times.
