# MITRE CAPEC/CWE downloads — CAPEC's "latest" alias is ~3 years stale; CWE's "latest" is 6 months old

Both CAPEC and CWE publish a conventionally-named "latest" static download
on their own subdomain, keyless, no API involved:

- `GET https://capec.mitre.org/data/xml/capec_latest.xml` → `200`,
  `Content-Type: text/xml`, `Content-Length: 3849998` (3.8 MB),
  `Last-Modified: Tue, 24 Jan 2023`. The XML root element itself carries
  `Name="CAPEC" Version="3.9" Date="2023-01-24"` — the version is embedded
  in the content, not just inferred from the HTTP header, and both agree:
  this "latest" alias has not moved in roughly three years relative to
  probe date (2026-10-05).
- `GET https://capec.mitre.org/data/csv/1000.csv.zip` → `200`,
  `application/zip`, `Content-Length: 379121`, same `Last-Modified: 24 Jan
  2023`.
- `GET https://cwe.mitre.org/data/xml/cwec_latest.xml.zip` → `200`,
  `application/zip`, `Content-Length: 2021351` (2.0 MB),
  `Last-Modified: Thu, 30 Apr 2026` — about 6 months before probe, far
  fresher than CAPEC's equivalent despite the identical `_latest` naming
  convention and a shared parent organization (MITRE).
- `GET https://cwe.mitre.org/data/csv/1000.csv.zip` → `200`,
  `application/zip`, `Content-Length: 641573`, same `Last-Modified: 30 Apr
  2026`.

A client treating "`*_latest.xml`" as synonymous with "current release" for
both catalogs would be correct for CWE and roughly three release cycles
behind for CAPEC. (CAPEC's actual latest published version at probe time
is well past 3.9 per MITRE's own changelog; this record only asserts what
the live download returns, not what the current version number should be.)

Reproduce:
```
curl -s https://capec.mitre.org/data/xml/capec_latest.xml | head -c 400 | grep -o 'Version="[^"]*" Date="[^"]*"'
# → Version="3.9" Date="2023-01-24"
curl -sI https://cwe.mitre.org/data/xml/cwec_latest.xml.zip | grep -i last-modified
# → Last-Modified: Thu, 30 Apr 2026
```

How observed: 2026-10-05T11:05:22Z–11:05:35Z, direct HTTPS GET/HEAD (curl,
default UA), no credential held or sent (none required).
