clawbot	fc651abe46	Trust the RFC 1918 ranges as proxies when TRUSTED_PROXIES is unset (closes #333) ... Unset or empty, TRUSTED_PROXIES now defaults to 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16, so a reverse proxy reaching the app over a Docker network or a private LAN gets per-client rate-limit buckets without configuration. A set value replaces the default; an unparseable one still fails startup. The startup warning for an empty list goes, with its test hook and test, since the default is no longer empty. The README's configuration table, Trusted proxies, upaas and reverse-proxy sections describe the new default and when to narrow it to the proxy alone. Model: opus-5-5	2026-09-29 07:29:26 +00:00

clawbot	977fe87588	Verify login credentials before spending rate-limit budget (closes #150) ... In the shipped default, any stranger denied the operator the only administrative path at 5 requests per minute: TRUSTED_PROXIES is empty, the README requires a reverse proxy, so every login POST shared one bucket keyed on the proxy. Credentials are now verified first and only a FAILED attempt spends budget, so a correct password is never throttled. Failures are counted per (client bucket, submitted username), bounded. Concurrent Argon2id verifications are capped at two, and the queue for them at 16 — because verifying first lets an attacker force a 64 MB hash per request, and bounding the wait alone bounds nothing. The issue's own recommendation was insufficient and is rejected here: keying by username stops an attacker locking out a DIFFERENT account, but this is a single-admin product with a predictable bootstrap username, so flooding the operator's own name still locks them out. This is speculative — it implements a corrected recommendation ahead of the owner's ruling so the decision can be made by merging or reverting. Three things are disclosed rather than glossed: online guessing rises from 5/min to roughly 27/s, because the 429 is a label on the response and not a gate in front of the hash; the residual exposure is a loss of login AVAILABILITY, not latency, and a determined flood still denies login while it runs, at ~400x the cost and clearing the moment it stops; and the endpoint should be provisioned for ~400 MB resident, not the 203 MB of live commitment it itemises. Independently reviewed four times. Reviewers disproved the suspected FIFO starvation by measurement, then caught two successive memory bounds the code did not have — the second by parking waiters and reading the heap rather than checking the arithmetic.	2026-08-18 01:55:41 +02:00
