* Add SSRF protection for custom geo downloads
Introduce SSRF-safe HTTP transport for custom geo operations by adding ssrfSafeTransport and isBlockedIP helpers. The transport resolves hosts and blocks loopback, private, link-local and unspecified addresses, returning ErrCustomGeoSSRFBlocked on violations. Update probeCustomGeoURLWithGET, probeCustomGeoURL and downloadToPathOnce to use the safe transport. Also add the new error ErrCustomGeoSSRFBlocked and necessary imports. Minor whitespace/formatting adjustments in subClashService.go, web/entity/entity.go and web/service/setting.go.
* Add path traversal protection for custom geo
Prevent path traversal when handling custom geo downloads by adding ErrCustomGeoPathTraversal and a validateDestPath() helper that ensures destination paths stay inside the bin folder. Call validateDestPath from downloadToPathOnce, Update and Delete paths and wrap errors appropriately. Reconstruct sanitized URLs in sanitizeURL to break taint propagation before use. Map the new path-traversal error to a user-facing i18n message in the controller.

* Fix bug
* **Fixes & Changes:**
1. **Fixed XPadding Placement Dropdown**:
- Added the missing `cookie` and `query` options to `xPaddingPlacement` (`stream_xhttp.html`).
- *Why:* Previously, users wanting `cookie` obfuscation were forced to use the `header` placement string. This caused Xray-core to blindly intercept the entire monolithic HTTP Cookie header, failing internal padding-length validations and causing the inbound to silently drop the connection.
2. **Fixed Uplink Data Placement Validation**:
- Replaced the unsupported `query` option with `cookie` in `uplinkDataPlacement`.
- *Why:* Xray-core's `transport_internet.go` explicitly forbids `query` as an uplink placement option. Selecting it from the UI previously sent a payload that would cause Xray-core to instantly throw an `unsupported uplink data placement: query` panic. Adding `cookie` perfectly aligns the UI with Xray-core restrictions.
### Related Issues
- Resolves#3992
* This commit fixes structural payload issues preventing XHTTP from functioning correctly and eliminates WebSocket log spam.
- **[Fix X-Padding UI]** Added missing `cookie` and `query` options to X-Padding Placement. Fixes the issue where using Cookie fallback triggers whole HTTP Cookie header interception and silent drop in Xray-core. (Resolves [#3992](https://github.com/MHSanaei/3x-ui/issues/3992))
- **[Fix Uplink Data Options]** Replaced the invalid `query` option with `cookie` in Uplink Data Placement dropdown to prevent Xray-core backend panic `unsupported uplink data placement: query`.
- **[Fix WebSockets Spam]** Boosted `maxMessageSize` boundary to 100MB and gracefully handled fallback fetch signals via `broadcastInvalidate` to avoid buffer dropping spam. (Resolves [#3984](https://github.com/MHSanaei/3x-ui/issues/3984))

When a client hit traffic/expiry limit, disableInvalidClients sets
client_traffics.enable=false and removes the user from Xray. GetClientTrafficByEmail
was overwriting that with settings.clients[].enable (admin config), so
ResetClientTraffic never saw the client as disabled and did not re-add
the user. Clients could not connect until manually disabled/re-enabled.
Now the DB runtime enable flag is preserved; reset correctly re-adds
the user to Xray.
Add a createRobustFastHTTPClient helper to configure fasthttp.Client with better timeouts, connection limits, retries and optional SOCKS5 proxy dialing. Validate and sanitize proxy and API server URLs instead of returning early on invalid values, and build telego.Bot options dynamically. Reduce long-polling timeout to detect connection issues faster and adjust update retrieval comments. Implement exponential-backoff retry logic for SendMessage calls to handle transient connection/timeouts and improve delivery reliability; also reduce inter-message delay for better throughput.
Add rate-limit friendly delays and context timeouts when sending backups via Telegram. Iterate admin IDs with index to sleep 1s between sends; add 30s context.WithTimeout for each SendDocument call and defer file.Close() for opened files; insert a 500ms pause between sending DB and config files. These changes improve resource cleanup and reduce chance of Telegram rate-limit/timeout failures.
- Add timestamp tracking for each client IP address
- Sort IPs by connection time (newest first) instead of alphabetically
- Automatically disconnect old connections when IP limit exceeded
- Keep only the most recent N IPs based on LimitIP setting
- Force disconnection via Xray API (RemoveUser + AddUser)
- Prevents account sharing while allowing legitimate network switching
- Log format: [LIMIT_IP] Email = user@example.com || Disconnecting OLD IP = 1.2.3.4 || Timestamp = 1738521234
This ensures users can seamlessly switch between networks (mobile/WiFi)
and the system maintains connections from their most recent IPs only.
Fixes account sharing prevention for VPN providers selling per-IP licenses.

Adds a scheduled GitHub Actions workflow (.github/workflows/cleanup_caches.yml) that runs weekly (and via workflow_dispatch) to delete Actions caches not accessed in the last 3 days. The job uses the gh CLI with the repository token and actions: write permission to list caches, filter by last_accessed_at against a 3-day cutoff, and delete matching cache IDs.
Removed verifyPeerCertByNames and pinnedPeerCertSha256 from inbound TLS settings and UI. Added verifyPeerCertByName and pinnedPeerCertSha256 to outbound TLS settings and updated the outbound form to support these fields. This change streamlines and clarifies certificate verification configuration between inbound and outbound settings.
Bump Xray-core version to v26.1.31 in build scripts and server logic. Update Go dependencies including gopsutil, bytedance/sonic, circl, miekg/dns, go-proxyproto, sagernet/sing, and others to their latest versions. Adjust version check in GetXrayVersions to require at least v26.1.31.
Replaces single UDP hop interval with separate min and max values in Hysteria stream settings. Updates model, JSON serialization, URL param parsing, and form fields for backward compatibility and enhanced configuration flexibility.
Introduces the pinnedPeerCertSha256 field to TlsStreamSettings in the JS model and adds a corresponding input in the TLS settings form. This allows users to specify SHA256 fingerprints for peer certificate pinning, enhancing security configuration options.
Introduces a 'congestion' option to Hysteria stream settings and updates the form to allow selection between BBR (Auto) and Brutal. Adds support for UDP masks, including model, serialization, and UI for adding/removing masks with type and password fields.
