Richard Palethorpe	3fa7b2955c	feat(pii): NER tier engine — privacy-filter.cpp backend + NER-centric PII filter (#10360) ... Squashed feat/pii-ner-tier-engine rebased onto master (was 45 commits; see backup/pii-ner-tier-engine-prerebase). Net change: - privacy-filter.cpp: standalone GGML engine for the openai-privacy-filter PII/NER token classifier, wired as a LocalAI gRPC backend (CPU/CUDA/Vulkan). TokenClassify moves off the patched llama.cpp path onto this backend. - PII filter reworked to be NER-centric (encoder/NER detection tier scanning whole conversations as one document), with a recreated bounded restricted- regex secret-matching pattern detector tier alongside it (per-model pii_detection.builtins / .patterns + core/services/routing/piipattern). - Detection labelled by source (ner vs pattern); backend trace / confidence / debug observability; analyze/redact exposed as a synchronous API. - Instance-wide default detector policy + per-usecase default-on; request filtering extended to completions, embeddings, edits & Ollama. - React UI: NER-centric PII editor, detector-models table, pattern/builtins editor, middleware default-policy UI. - Gallery: privacy-filter-multilingual token-classify model + NER install filter; token_classify known_usecase; batch sized to context for NER models. privacy-filter backend registered in the backend gallery (cpu/vulkan/cuda-13 meta + image entries with a capabilities map) matching its CI matrix jobs, and an /import-model auto-detect importer (PrivacyFilterImporter, narrow privacy-filter GGUF detection) replacing the prior pref-only registration. Reconciled against master's independent evolution: - Dropped master's PIIPatternOverrides feature (global-pattern runtime overrides + /api/pii/patterns API + runtime_settings.json persistence). The per-model NER + pattern-detector design supersedes it; it was built on the global redactor pattern set this branch replaced. - Reverted the llama.cpp Score carry-patch (0006-server-task-type-score): removed the patch and restored master's grpc-server.cpp Score RPC (direct llama_decode, slot-loop bypass) and LLAMA_VERSION pin, plus master's model_config validation forbidding score + chat/completion/embeddings on llama-cpp. token_classify is unaffected (it runs on the privacy-filter backend, not llama-cpp).

Richard Palethorpe	085fc53bbc	fix(router): production-ready request router + auto-size batch for embedding/rerank (#10104) ... * fix(router): score classifier production-readiness Conversation trimming runs through the classifier model's chat template and trims by exact token count, sized to the model's n_batch which is now scaled to context so long probes can't crash the backend. Missing chat_message templates are a hard error at router build time. Router- facing factories (Embedder/Scorer/Reranker/TokenCounter) re-resolve ModelConfig per call so a model installed post-startup doesn't bind a stub Backend="" config and silently fall into the loader's auto- iterate path. New 'vector_store' backend trace recorded inside localVectorStore on every Search/Insert — including the backend-load-failure path that previously vanished into an xlog.Warn — with outcome tagging (hit/miss/empty_store/backend_load_error/find_error/insert_error/ok). Companion cleanup drops misleading similarity:0 and input_tokens_count:0 from non-hit and text-mode traces. Gallery local-store-development aliases to 'local-store' so the master image satisfies pkg/model.LocalStoreBackend lookups from the embedding cache. Misc: llama-cpp TokenizeString reads the correct 'prompt' JSON key (the original bug); ModelTokenize nil-guard; non-fatal mitm proxy startup; PII 'route_local' renamed to 'allow' with docs/UI in sync; model-editor footer no longer eats the edit area on small screens; several config-editor template/dropdown/section fixes. Tests: e2e router specs (casual/code-hint + long-conversation trim), vector_store trace specs, lazy-factory specs, gallery dev-alias resolution, Playwright trace badge + scroll regression.

With batch left at the 512 default, the backend rejects longer inputs with "input is too large to process", silently capping a large-context embedder (e.g. 8k/32k) at 512 tokens. Size n_batch to the context for these single-pass usecases, mirroring the existing FLAG_SCORE behaviour; an explicit batch: still wins. Extracts EffectiveContextSize/EffectiveBatchSize from grpcModelOpts so the effective decode window has one home for other callers to reuse. Adds an e2e-aio regression test that embeds a >512-token input. The AIO embedding model is switched to nomic-embed-text-v1.5 (2048 context) because the previous granite model was capped at 512 tokens and could not exercise the larger batch.

The vendored llama.cpp server caps causal output rows at n_parallel, so the default of 1 aborts with GGML_ASSERT(n_outputs_max <= cparams.n_outputs_max) on multi-token route labels. Set options: [parallel:64] on both arch-router quant entries to lift the cap; kv_unified (the grpc-server default) keeps the full context per sequence, so this does not split the KV cache.

Richard Palethorpe	12d1f3a697	security(http): refuse redirects on outbound clients via hardened pkg/httpclient (#10087) ... LocalAI's outbound HTTP clients used Go's default redirect policy, which follows up to 10 redirects. On a cross-host redirect Go forwards custom request headers — including credential headers such as Anthropic's x-api-key — to the redirect target (Go strips Authorization, Cookie and WWW-Authenticate cross-host, but NOT arbitrary custom headers). An attacker able to elicit a redirect from an upstream (a hijacked or spoofed upstream, DNS trickery, or a malicious upstream_url) then harvests the operator's provider API key. This was first reported against the cloud-proxy / MITM PII path (GHSA-3mj3-57v2-4636); the same class affects every other outbound client. Rather than patch each call site, add pkg/httpclient as the one sanctioned constructor for outbound HTTP and route everything through it. pkg/httpclient: - New(...) refuses redirects, TLS 1.2 floor, no body deadline (streaming/SSE safe) - NewWithTimeout(d) simple request/response calls - WithFollowRedirects opt-in following that still strips credential headers on any cross-host hop; different scheme/host/port == different origin, guarding the curl CVE-2022-27774 port-confusion class - WithTransport(rt) keep a custom transport (IP-pin, HTTP/2, a credential-injecting RoundTripper) - HardenedTransport() base transport with the TLS floor + bounded setup - Harden(c) apply the policy to a library-supplied *http.Client - NoRedirect the CheckRedirect policy; wraps ErrRedirectBlocked Lint: a forbidigo rule flags http.DefaultClient and http.Get/Post/ PostForm/Head, pointing at pkg/httpclient (.golangci.yml, .agents/coding-style.md). forbidigo cannot match the &http.Client{} composite literal without also flagging legitimate *http.Client type references, so that form is enforced by review. Migrates every non-test outbound call site across core/, pkg/, cmd/, and the Go backend (backend/go/cloud-proxy). Credential-bearing and internal-RPC clients refuse redirects; download / CDN / registry clients use WithFollowRedirects so they keep working while stripping secrets cross-host. The only credential-bearing client that follows redirects is the gated-download path (pkg/downloader/uri.go), which strips the token on the cross-host hop to the CDN. Hardening this closes, in passing: - MCP remote-server bearer token leaking via a redirect (the RoundTripper re-injected Authorization on every hop) - agent multimedia/webhook clients leaking user-supplied auth headers - cors_proxy following redirects, bypassing its SSRF IP-pin - downloader's authorized read path leaking the token cross-host Fixes: GHSA-3mj3-57v2-4636 (cloud-proxy leaks operator provider API key (x-api-key) to attacker host on cross-host redirect) Reported-by: tonghuaroot Assisted-by: Claude:claude-opus-4-8 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com>	2026-05-30 12:04:10 +02:00
Richard Palethorpe	6a80e23733	feat(middleware): Model routing, PII filtering, Cloud model proxies (#9802) ... Add a routing middleware stack and a cloud-proxy backend. * cloud-proxy: a Go gRPC backend that forwards OpenAI- and Anthropic-shaped chat requests to upstream providers, with an optional translate mode (OpenAI request -> Anthropic /v1/messages -> OpenAI response) and full tool-calling support. * routing: admission control, content-aware model routing (embedding cache + classifier + rerank + Arch-Router score), PII detection/redaction (regex + NER) with streaming filter and OpenAI/Anthropic adapters, and a per-user/per-key billing recorder backed by GORM or in-memory storage. * middleware: UsageMiddleware records usage via the billing recorder, plus admission, route-model, usage-stamp and trace middlewares. * observability: BackendTrace ring buffer stores full request bodies (capped), MITM proxy emits structured trace events, and router classifier decisions surface at /api/router/decide. * gallery: Arch-Router-1.5B (Q4_K_M and Q8_0). * UI: cloud-proxy model-editor fields, classifier system-prompt and score-normalization config, and a Traces page rendering request bodies.
