Services: nginx refuses /internal/ and /metrics case-insensitively (#17)

OP OpenVibers committed 10 Oct 2026 · da2356d562 · 1 file, +2 −2

nginx config only. Express routes case-insensitively, so a case variant such as `/Internal/events` or `/METRICS` slipped past the case-sensitive `location /internal/ { return 404; }` and `location = /metrics { return 404; }` blocks and reached the app. Those paths were still guarded in the app (the Events signature, the loopback check on metrics). Both blocks are now `location ~* ^/internal(/|$)` and `location ~* ^/metrics(/|$)`. The independent security reviews of 2026-10-09/10 found this in several services; this applies it network-wide.
