Change TunSettings to support separate IPv4/IPv6 MTU values and add gateway, DNS, autoSystemRoutingTable and autoOutboundsInterface properties. Introduces _normalizeMtu to accept legacy single-value or array forms and provide sensible defaults. Update fromJson/toJson to handle new fields and preserve backward compatibility. Update tun form UI to expose MTU IPv4/IPv6 inputs, Gateway/DNS tag selects, Auto Routing Table and Auto Outbounds input.
Expose an ipsBlocked array on Outbound.FreedomSettings and wire it into the outbound form. The constructor now defaults fragment to {} and noises/ipsBlocked to arrays for robustness; fromJson/toJson handle ipsBlocked and omit it when empty. The outbound HTML adds a tag-style <a-select> bound to outbound.settings.ipsBlocked (with comma tokenization and placeholder) so users can enter IP/CIDR/geoip entries.
Update Go toolchain to 1.26.2 and upgrade multiple direct and indirect dependencies for bug fixes, compatibility and improvements. Notable bumps include github.com/mymmrac/telego v1.7.0→v1.8.0, github.com/valyala/fasthttp v1.69.0→v1.70.0, golang.org/x/crypto v0.49.0→v0.50.0, golang.org/x/sys v0.42.0→v0.43.0, golang.org/x/text v0.35.0→v0.36.0, go.mongodb.org/mongo-driver/v2 v2.5.0→v2.5.1, and updates to several mattn, pires, sagernet and golang.org/x/* packages. Regenerated go.sum to reflect the updated module checksums.
Replace legacy KCP buffer options with cwndMultiplier and maxSendingWindow across models and UI. Updated KcpStreamSettings in web/assets/js/model/inbound.js and web/assets/js/model/outbound.js (constructor, fromJson and toJson) to remove congestion/readBuffer/writeBuffer and use cwndMultiplier/maxSendingWindow instead. Updated web/html/form/outbound.html to reflect the new KCP fields in the stream form and to include extensive template formatting/markup cleanup for consistency and readability.
Configure session cookie options centrally in initRouter and remove per-login MaxAge handling. Deleted SetMaxAge helper and its use in the login flow; session.Options are now applied once using basePath with HttpOnly and SameSite defaults, and MaxAge is set only when the stored setting is available and >0. Also make CookieManager.setCookie treat exdays as optional (only add expires when provided) and stop using a hardcoded 150-day expiry for the lang cookie in the JS language manager.

Replace the previous flat settings map for VLESS outbound with a vnext/users structure. Encryption is now pulled from inbound settings into the user object, a level field (8) is added, and client id and flow are preserved. Address and port are nested under vnext and outbound.Settings is set to {vnext: [...]}, aligning the outbound format with the expected VLESS schema.

* 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.

Introduce a CodeQL analysis workflow (CodeQL Advanced) that runs on push, pull_request, and a weekly schedule. It initializes and runs github/codeql-action for a matrix of languages (actions, go, javascript-typescript), configures build-mode per-language, sets minimal read/write permissions for security-events, packages, actions and contents, and selects macOS for Swift or Ubuntu otherwise.

Unsafe type assertion `xhttp["mode"].(string)` panics when mode is
nil (e.g., when xhttpSettings only contains path without mode). The
panic is caught by Gin's recovery middleware and returned as HTTP 500.
Use comma-ok pattern matching the fix already applied to gRPC's
authority field in 21d98813.
Fixes#3987
* feat: implement real-time traffic monitoring and UI updates using a high-performance WebSocket hub and background job system
* feat: add bulk client management support and improve inbound data handling
* 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))

Update go toolchain to 1.26.1 and upgrade multiple direct and indirect modules (examples: github.com/gin-contrib/gzip v1.2.6, github.com/gin-contrib/sessions v1.1.0, github.com/go-ldap/ldap/v3 v3.4.13, github.com/goccy/go-json v0.10.6, github.com/pelletier/go-toml/v2 v2.3.0, github.com/shirou/gopsutil/v4 v4.26.3, github.com/xtls/xray-core v1.260327.0, golang.org/x/crypto v0.49.0, google.golang.org/grpc v1.80.0). go.sum updated accordingly to lock the new versions. Routine dependency refresh to pull in fixes and improvements.
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.
it should be 'default' runlevel when add x-ui service to openrc, default is 'sysinit' runlevel. 'sysinit' runlevel is unnecessary,maybe.
if not, there is an error when call to function 'check_enabled()' as command 'grep default -c' can`t print 'default' runlevel.
check_enabled() {
if [[ $release == "alpine" ]]; then
if [[ $(rc-update show | grep -F 'x-ui' | grep default -c) == 1 ]]; then
return 0
else
return 1
