hono is vulnerable to Sensitive Information Disclosure
53
Medium Risk
This Affects:
honoTL;DR
The cache middleware can cache responses that vary by Authorization or Cookie without skipping storage for per-user variants. A response generated for one authenticated user can then be reused for a different user under shared cache keys. This can expose user-specific data to unintended recipients. The fix treats Vary: Authorization and Vary: Cookie as cache-skip signals so user-scoped responses are not shared.
