Test-connection's "连接失败" was nearly useless for debugging because
two layers conspired to swallow the actual upstream error:
Backend swallow
---------------
checkChatModelConnection and CheckASRModel pattern-matched on the
upstream error string (401 / 404 / timeout / ...) and replaced it with
a fixed Chinese hint. The original SDK message (request URL, response
body, provider's error code description) was discarded.
Refactor: extract classifyConnectionError(errMsg) — returns just the
short Chinese hint. Callers combine "<hint>：<raw err>" so the hint
indicates "where to start looking" and the raw error shows "what
actually happened". The status-400 special-case (endpoint reachable,
parameter mismatch only) still returns success.
Frontend swallow
----------------
ModelEditorDialog.testConnection ignored result.message on success
paths (fine), but also overwrote it with a generic i18n string on
failure paths and 4xx rejections — even though axios's interceptor
already lifts the backend's error.message to error.message. Failure
branch now uses error?.message || result.message as the toast content;
i18n fallback only when neither is present.
SSRF allowlist hint
-------------------
SSRF validation failures previously returned
"Base URL 未通过安全校验: <reason>" with no mention of how to recover
(the allowlist is server-side, not configurable in the UI). Operators
hit it and were stuck.
New utils.FormatSSRFError(label, rawURL, err) wraps the error with
guidance to add the host to SSRF_WHITELIST_EXTRA (the operator-facing
append-only escape hatch — SSRF_WHITELIST itself is the project's
baseline). The hint echoes the failed host so it can be copy-pasted
straight into the env var:
Base URL 未通过安全校验：DNS resolution failed for hostname
test.local.com ... 如该地址确实可信，请联系运维在服务端环境变量
SSRF_WHITELIST_EXTRA 中加入该主机（支持精确域名 / *.example.com
通配 / IP / CIDR），示例：SSRF_WHITELIST_EXTRA=test.local.com,
*.example.com,10.0.0.0/8
All SSRF call sites switch to the helper:
initialization (CheckRemoteModel / TestEmbedding / CheckRerank /
CheckASR / TestMultimodal / batch validation), model CRUD,
mcp_service CRUD, knowledge URL ingest, system ReconnectDocReader.
- Added isValidURL function to validate URLs before rendering links in the document content component, preventing invalid links from being clickable.
- Refactored timeout handling in KnowledgeBase.vue to use setTimeout instead of setInterval, improving performance and resource management.
- Ensured that timeouts are cleared appropriately to avoid memory leaks and unnecessary polling.
This update improves the robustness of URL handling and optimizes the component's performance.
- Keep strict mode blocking all direct IPs (IPv4 and IPv6 uniformly)
- Unify all SSRF call sites to use ValidateURLForSSRF (whitelist-aware)
- Add Teredo (2001:0000::/32) and 6to4 (2002::/16) tunnel detection
- Make redirect handler and DNS pinning respect SSRF_WHITELIST
- Unexport isSSRFSafeURL to prevent future callers bypassing whitelist
- Add scheme validation for whitelisted redirect targets
- Document IPv6 whitelist syntax in .env.example
- Add comprehensive IPv6 test coverage
- Replaced the default DialContext with SSRFSafeDialContext in the raw HTTP client to improve security against DNS rebinding attacks.
- Added SSRF validation for BaseURL and endpoint in NewRemoteAPIChat and chat methods, ensuring safer URL handling.
- Updated security utility functions to provide consistent SSRF checks across the application.
- Added timezone and language settings to the environment configuration.
- Introduced built-in agent configurations with multilingual support for various agents.
- Updated Docker Compose to utilize new environment variables for timezone and language.
- Created new prompt templates for question generation, summary generation, and keywords extraction.
- Removed the image storage handling from the `_resolve_images` function, which now only decodes images and returns them as inline bytes.
- Updated the function's docstring to clarify that image persistence is managed by the Go App, and the return value for `image_dir_path` is always empty.
- Adjusted related gRPC and protobuf files to remove the `ConvertToPDF` method and its associated types, streamlining the API.
- Enhanced security measures in the frontend by implementing a placeholder for provider images and ensuring proper hydration of protected file images.
These changes improve the clarity and efficiency of image processing and API interactions within the application.
- Added `SafePathUnderBase` to prevent path traversal by ensuring file paths remain within a specified base directory.
- Introduced `SafeFileName` to validate and sanitize file names, disallowing path traversal and empty names.
- Implemented `SafeObjectKey` to validate object keys for storage, ensuring they do not contain path traversal sequences.
- Updated file handling methods in `cos.go`, `local.go`, and `minio.go` to utilize these new validation utilities, enhancing security against invalid file paths and names.
This update improves the robustness of file operations by enforcing strict validation rules, thereby mitigating potential security risks.
- Introduced a new validatedParams struct to hold validated input along with DNS-pinned host/IP for SSRF protection.
- Updated the validateParams function to validate and resolve the host to a single public IP, ensuring safe outbound fetches.
- Modified executeFetch and fetchHTMLContent methods to utilize the new validatedParams for improved security and clarity.
- Enhanced logging to reflect the display URL and provide better context during fetch operations.
This update strengthens the web fetch tool's security against SSRF attacks and improves the overall robustness of URL handling.
Add SSRF protection by validating redirect targets and resolved IPs,
blocking internal hostnames, restricted suffixes, and private IP ranges
including Docker and Kubernetes internal endpoints.
