  "details": "Vulnerability report without repro case. Repro case may be added later after harness is complete.\n\n**Preconditions (4):**\n- Pod-network reachability to :18002 (no auth)\n- Tenant can create EnvoyExtensionPolicy (baseline)\n- Attacker pod floods GET while churning EnvoyExtensionPolicy with distinct Wasm URLs\n- Read at :153 must overlap a write at :201/:209 (probabilistic, attacker controls both rates)\n\n**Description:**\n\nhttpserver.go:153 reads s.mappingPath2Cache with no lock while httpserver.go:201/209 write it under s.Lock(); the struct uses a plain map. Writer is tenant-reachable via EnvoyExtensionPolicy translation, reader is pod-network-reachable on :18002 with per-request goroutines. Go\u0027s concurrent map read+write detection calls runtime.throw, which net/http\u0027s per-conn recover cannot catch, so the controller process exits \u2014 cross-tenant control-plane DoS.
