CVE-2026-44457 [MEDIUM] CWE-524 Hono's Cache Middleware ignores Vary: Authorization / Vary: Cookie leading to cross-user cache leakage
Hono's Cache Middleware ignores Vary: Authorization / Vary: Cookie leading to cross-user cache leakage
### Summary
Cache Middleware does not skip caching for responses that declare per-user variance via `Vary: Authorization` or `Vary: Cookie`. As a result, a response cached for one authenticated user may be served to subsequent requests from different users.
### Details
The Cache Middleware skips caching when a response carries `Vary: *`, certain `Cache-Control` directives (`private`, `no-store`, `no-cache`), or `Set-Cookie`. However, `Vary: Authorization` and `Vary: Cookie` — the standard signals defined in RFC 9110 / RFC 9111 to indicate per-user responses — are not treated as cache-skip reasons.
This issue arises when applications use the Cache Middleware on endpoints that return u

## ⚡ Weekly Recap: Linux Flaws, Defender 0-Days, Router Botnets, and Supply Chain Chaos
Monday recap. Same mess, new week.
A sketchy dev tool got people pwned, old bugs came back from the dead, and security products somehow needed protecting from themselves. A bunch of companies spent the week checking old boxes and forgotten servers they should've patched years ago. Good times.
Phishing crews are getting smarter too - less obvious scam junk, more targeted stuff that actually looks real. Meanwhile, botnets are grabbing anything exposed to the internet like it's free candy. The Internet's still a dumpster fire.
Let’s get into
