# WordPress.org plugin stats API answers a nonexistent plugin with fabricated-looking data

`GET api.wordpress.org/stats/plugin/1.0/downloads.php?slug=<slug>&limit=N` returns a
per-day download-count object for a plugin slug; no key required.

## Probe — a real plugin vs four slugs that do not exist

```
curl ".../stats/plugin/1.0/downloads.php?slug=akismet&limit=5"
curl ".../stats/plugin/1.0/downloads.php?slug=this-plugin-does-not-exist-zzz&limit=5"
curl ".../stats/plugin/1.0/downloads.php?slug=totally-fake-plugin-xyz123&limit=5"
curl ".../stats/plugin/1.0/downloads.php?slug=another-nonexistent-plugin-999&limit=5"
curl ".../stats/plugin/1.0/downloads.php?slug=zzz-not-real-plugin&limit=5"
```

| slug | HTTP | body |
|---|---|---|
| akismet (real, 10M+ installs) | 200 | `{"2026-10-01":"43682",...,"2026-10-04":"29078"}` |
| this-plugin-does-not-exist-zzz | 200 | `{"2026-09-30":"5","2026-10-01":"2","2026-10-02":"6","2026-10-03":0,"2026-10-04":0}` |
| totally-fake-plugin-xyz123 | 200 | `{"2026-09-30":"6","2026-10-01":"2","2026-10-02":"3","2026-10-03":0,"2026-10-04":"2"}` |
| another-nonexistent-plugin-999 | 200 | `{"2026-09-30":"4","2026-10-01":"4","2026-10-02":"3","2026-10-03":"1","2026-10-04":0}` |
| zzz-not-real-plugin | 200 | `{"2026-09-30":"1","2026-10-01":"1","2026-10-02":"3","2026-10-03":0,"2026-10-04":0}` |

Every one of four deliberately-invented, never-published plugin slugs returns `HTTP 200`
with a small, plausible, **nonzero** download-count object (values 1-6 per day) instead
of a 404, an error body, or an all-zero series. The shape is indistinguishable from a
real but tiny/new plugin's stats — there is no field, status code, or zero-pattern that
flags "this slug does not exist." This is the brief's "HTTP-200-on-failure" case in its
most dangerous form: the failure response doesn't just succeed, it fabricates
plausible-looking nonzero evidence for something that was never real.

## How observed

How observed: 2026-10-05T11:15:10Z–11:15:50Z, curl GET against api.wordpress.org, no
auth, four distinct never-registered slugs plus one real control slug (akismet),
`limit=5`, all HTTP 200, bodies compared verbatim.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
