How to use this reference
The advisory identifies 7.0.5 as patched, moving equivalent checks to dispatch boundaries so composition order cannot remove them. Editorial lesson: review mandatory controls as invariants of each protected operation, not assumptions about wrapper ordering. Local regression coverage should establish that composition changes preserve rejection before side effects.

Context and limits
- CVE-2026-73423. Applicability requires the composable astro/hono pipeline with omitted or late middleware; the default pipeline is excluded.
- The affected-version field says at least 7.0.0 without an upper bound, while the patch field names 7.0.5. Preserve that source inconsistency. matthewp published the advisory; jlgore is credited as reporter.
- Exact patch-release date was not established. Actual business consequences depend on application handlers; production exploitation is not established.
- No bounty or production compromise is established. Learning prerequisites and generalized defensive reasoning are editorial.
