Technical description

Xibo is an open source digital signage platform with a web content management system and Windows display player software. Prior to 4.4.3, missing authorization on `POST /displaygroup/criteria/{displayGroupId}` allows an authenticated user to send criteria updates to any display via `XMR`. These criteria determine schedule changes and can alter playback, for example by causing content scheduled for rainy weather to play when it is not raining. Exploitation requires `Schedule Criteria` to be in use on the CMS. This issue is fixed in version 4.4.3.

———Domoticz is a free, open source home automation system for Linux, Windows, macOS, and Raspberry Pi. Prior to 2026.3, the `udevices` JSON command handler, `Cmd_UpdateDevices` in `main/WebServerCmds.cpp`, performed no `session.rights` check before invoking a Lua parser script, while its sibling command handlers gate access by role. A low-privilege authenticated user could trigger execution of an existing operator-installed Lua parser script with attacker-controlled input through the `GET /json.htm` endpoint with `type=command` and `param=udevices`. The `script` parameter also lacked a `..` path-traversal guard: `CLuaHandler::executeLuaScript` in `main/LuaHandler.cpp` constructed the filename from the parser directory and the supplied script name before passing it to `luaL_loadfile`. Execution is limited to already-installed valid Lua files; this is not arbitrary code execution, and the advisory states that file-write and upload paths require administrator privileges. This issue is addressed in version 2026.3.4h CVE-2026-615717.3 HIG

———AVideo is a video-sharing Platform. Prior to 8.1.0, the encoder lacks a global authentication layer and exposes control and status PHP endpoints to anonymous network callers. `view/run.php` has a commented-out guard and invokes `Encoder::run()`. `view/queue.json.php` calls `Encoder::getAll(true)`, reveals streamer URLs through `getSiteURL()`, and triggers processing with `execRun()`. `view/status.php` returns `Access-Control-Allow-Origin` with a wildcard, reads the queue, triggers processing, and exposes host memory statistics through `ServerMonitor::getMemory()` when `serverStatus` is set. `view/listFiles.json.php` checks only `Login::canBulkEncode()`, which admits anonymous callers whenever `disableBulkEncode` is empty, the default. Its `path` parameter is resolved with `realpath()` and listed with `scandir()` without a base-directory restriction. An unauthenticated attacker can drive the privileged queue processor, read queue and streamer-site information, obtain memory statistics and enumerate media file names and paths in any directory readable by the web-server user. Enumeration is limited to configured media extensions and does not itself disclose arbitrary file contents. This issue is fixed in version 8.1.0.5h CVE-2026-1188047.5 HIG

———Bricks Builder 2.4.3 and before contains a broken access control vulnerability that allows unauthenticated attackers to access restricted post content by submitting crafted post_status and post_type values in the originalQueryVars parameter to the POST /wp-json/bricks/v1/query_result REST endpoint using a publicly obtainable nonce. Attackers can set post_status to draft or private, or post_type to shop_coupon, to disclose unpublished posts, private content, and WooCommerce coupon data that is otherwise blocked by the standard WordPress REST API routes.5h CVE-2026-1187576.5 MED

———PiWeb Disable payment method / Partial payment for WooCommerce before 1.1.10.9 contains a missing authorization vulnerability in the update_fees AJAX handler that allows unauthenticated attackers to modify and read other customers' orders. Attackers can reuse a nonce from their own order-pay page and supply sequential order_id values to change payment methods, recalculate fees, and disclose order line items and totals.5h CVE-2026-1187545.3 MED

———Dolibarr ERP CRM before 24.0.2 contains a missing authorization vulnerability in htdocs/public/recruitment/view.php that allows unauthenticated attackers to view unpublished draft job positions. Attackers can enumerate sequential provisional references via the ref parameter to read titles, descriptions, salary budgets, and recruiter names and emails.5h CVE-2026-116794—

———russh is a Rust SSH client and server library that includes an SSH agent protocol implementation. From 0.50.0-beta.12 until 0.65.0, the agent server's Connection::try_sign path in russh/src/keys/agent/server.rs recognizes SSH_AGENT_CONSTRAIN_CONFIRM but returns a hard-coded successful result instead of calling Agent::confirm. In applications that override Agent::confirm to require user approval or another policy check, a process that can reach the agent socket, including the remote side of a forwarded agent, can use a key added through ssh-add -c without that check and can authenticate or sign data as the user while the key remains loaded. The separate Agent::confirm_request hook still runs for every signing request, so checks implemented there remain effective, and implementations that retain the default always-successful Agent::confirm do not lose an approval check through this regression. This issue is fixed in version 0.65.0.9h
