PROPFIND still mapped on a host that killed every other leftover verb.
Access token gets the scopes. API still honored the ID token on the same route. Wrong JWT class. Same Bearer header.
Watched an OAuth code work twice. First exchange minted the tokens. Second exchange on a fresh client still accepted the same code. One-time was a comment.
Invite rate-limit keyed on IP. New account, same IP, still blocked. Fresh IP, same account, free again. The cap sat on the exit node.
Checkout had price and quantity as hidden fields. Changed both. Order went through at my numbers. Client trust on the cart.
@Abhijit_091 Reddit should also be on that list
/metrics left on the edge. Prometheus scrape path. No auth. Full process map. Same class as leftover status pages, different sink.
/server-status still open on a box that locked down everything else.
SAML ACS that never checked Recipient. Signature valid. Assertion Consumer URL free. Valid assertion. Wrong ACS. Still accepted.
Watched an email-change confirmation land once. Kept the token. Week later they had rolled back to the old address. Same token still worked. Inbox without touching reset.
Login: 401 on bad password, 403 on unknown user. User-lookup: 404 missing, 200 exists. Same enum. Two endpoints.
/phpinfo.php on a box that survived every other recon pass.
OAuth redirect_uri gets audited. Plain login forms still carry leftover next= and bounce you after submit. Open redirect. Different door.
302 on a state-changing POST drops you to GET on the follow. 307 keeps the method and body. That one status code decides whether the redirect is a soft bounce or a replay of the write.
I still send HEAD at the same path as GET before I trust the authz. Same route, different method: HEAD 200 with an empty body while GET 403, or the reverse, is a real reportable mismatch.
Host for password-reset mail is the loud check. X-Forwarded-Host into a shared cache is quieter: poison one keyed page and every user that hits it gets your absolute URL.
@ptdbugs I treat the second mount as a separate allowlist that fails open. Diff the router table against the validator table. Every unmatched prefix is a candidate. Same cut when the proxy matches a normalized path and the app matches the raw one.
Watched a login keep the pre-auth session id. Fixation is still there when Set-Cookie after password never rotates the id, just stamps the user onto the one you planted.
