Vue d’ensemble
API versioning attacks
When it applies
The API exposes multiple versions and a vulnerability fixed in the current version still lives in an older or undocumented one. Old versions rarely get the same auth, validation, or rate-limit hardening.
Why it works
Teams patch the latest version and leave /v1 (and /beta, /internal, dated versions) running
for backward compatibility. Those endpoints often skip a fix, lack a new authz check, or expose
fields later removed — same data, weaker guard.
Method
- Enumerate versions: swap the version in path (
/v1↔/v2↔/v3), header (Accept: application/vnd.api+json;version=1,X-API-Version), or subdomain (api-v1.,legacy.). Fuzz withffuf. - Diff behaviour: take a request that's now blocked/fixed on the current version and replay it
against older ones — missing auth, mass assignment (→
api-mass-assignment), BOLA (→api-bola), verbose fields, or no rate limit. - Mine sources for old versions: mobile apps, JS bundles, wayback, and public API docs often reference deprecated versions still live.
- Re-test every known bug per version — a fix in v2 is often absent in v1.
Gotchas
- A 404 on
/v1root doesn't mean v1 is gone — test specific known endpoints under it. - Header/media-type versioning is easy to miss vs path versioning — enumerate all three.
- Old versions may lack rate limits, enabling brute force the new one blocks.
Verify success
A vulnerability reproducible on an older/undocumented API version that is patched or better-guarded on the current one.

Old versions rarely get the same auth, validation, or rate-limit hardening. ## Why it works Teams patch the latest version and leave `/v1` (and `/beta`, `/internal`, dated versions) running for backward compatibility. Those endpoints often skip a fix, lack a new authz check, or expose fields later removed — same data, weaker guard. ## Method 1. **Enumerate versions**: swap the version in path (`/v1`↔`/v2`↔`/v3`), header (`Accept: application/vnd.api+json;version=1`, `X-API-Version`), or subdomain (`api-v1.`, `legacy.`). Fuzz with `ffuf`. 2. **Diff behaviour**: take a request that's now blocked/fixed on the current version and replay it against older ones — missing auth, mass assignment (→ `api-mass-assignment`), BOLA (→ `api-bola`), verbose fields, or no rate limit. 3. **Mine sources for old versions**: mobile apps, JS bundles, wayback, and public API docs often reference deprecated versions still live. 4. **Re-test every known bug per version** — a fix in v2 is often absent in v1. ## Gotchas - A 404 on `/v1` root doesn't mean v1 is gone — test specific known endpoints under it. - Header/media-type versioning is easy to miss vs path versioning — enumerate all three. - Old versions may lack rate limits, enabling brute force the new one blocks. ## Verify success A vulnerability reproducible on an older/undocumented API version that is patched or better-guarded on the current one. ## References OWASP API Security Top 10 (2023) API9; API inventory/versioning guidance.
