Descripción técnica

fast-agent is a framework for building, running, and evaluating AI agents with Model Context Protocol support. Prior to 0.7.21, fast-agent serve uses HTTP transport bound to 0.0.0.0 on port 8000 without authentication, allowing any network client that can reach the /mcp endpoint to invoke the exposed agent tool. When the server is started with --shell, the agent can call the local execute tool implemented by tools/local_shell_executor.py, so an unauthenticated remote client can cause operating-system commands to run as the server user; without --shell, the client can still consume the operator's model and configured MCP tools. The defaults are defined in cli/commands/serve.py and mcp/server/agent_server.py, and the non-interactive server permission prompt does not prevent the described access. This issue is fixed in version 0.7.21.

———Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 5.2.3, the administrative BullMQ dashboard was mounted without an authentication check. The vulnerable surface is the Bull Board/BullMQ administration dashboard at /apps/queues. A remote unauthenticated attacker reaches /apps/queues on a Chartbrew instance where Redis and BullMQ are enabled and a reverse proxy does not independently block the route. The dashboard trusted network reachability as authorization and exposed its queue-management interface directly. Redis and BullMQ must be enabled and the route must be reachable. Available actions depend on the installed Bull Board version and queue state, while confidentiality depends on job payload and log contents. An unauthenticated user can inspect exposed job payloads and logs and, when enabled by the installed version and queue state, retry or delete jobs or otherwise alter queue processing, affecting confidentiality, integrity, or availability. This issue is fixed in version 5.2.3.6h CVE-2026-1023448.1 ALT

———Lavish is the new editor for your HTML artifacts. Prior to 0.1.43, the lavish-axi loopback HTTP server did not authenticate requests or validate Host and Origin values on session, artifact, prompt, and polling routes. A website visited while the server is running can use DNS rebinding to send same-origin browser requests to the local service. POST /api/sessions accepts a caller-selected file path and returns its deterministic session key; GET /artifact/:key/index.html then returns the file contents, allowing disclosure of any file readable by the server process without an existing session. An attacker can also queue text through POST /api/:key/prompts for an active agent session when the artifact path is known or guessed. Visiting the attacker-controlled website is the required user interaction. This vulnerability is fixed in 0.1.43.6h CVE-2026-659608.8 ALT

——0Tetragon is an eBPF-based security observability and runtime enforcement project. Versions before 1.7.0 can use a Helm default that exposes the privileged Tetragon gRPC API through an unauthenticated TCP listener on localhost:54321. An attacker who can run or compromise same-node hostNetwork pods can reach the listener and invoke privileged methods without authentication. These methods can add, delete, or reconfigure tracing policies and change debug settings, potentially resulting in privilege escalation or container escape. Version 1.7.0 changes the default endpoint to a Unix-domain socket. Deployments that do not expose an unauthenticated TCP listener are not affected.7h CVE-2026-330508.8 ALT

——0GeoNode is a geospatial content management system, a platform for the management and publication of geospatial data. Prior to 5.1.0, a crafted vector file layer name supplied during upload allows a low-privileged remote user to inject shell syntax and execute arbitrary operating-system commands on the GeoNode server. This issue is fixed in version 5.1.0.6h CVE-2026-1240277.5 ALT

——0ChatWiki before 2.10.0 contains a missing authentication vulnerability in the GET /manage/getLibRawFileOnePage route that allows unauthenticated attackers to read other tenants' documents. Attackers can enumerate sequential admin_user_id and file id query parameters, bypassing the ownership check, to retrieve PDF-rendered pages of any tenant's knowledge-base documents.7h CVE-2026-1239964.6 MED

——0Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains a missing authentication vulnerability in the UPnP/DLNA RenderingControl service on TCP port 38400 that allows a LAN-adjacent attacker to issue SetVolume, SetMute, and SelectPreset(FactoryDefaults) commands after a one-time DLNA pairing with no per-command authentication or session token. Attackers can send a continuous loop of unauthenticated commands to override the physical remote, change volume and mute, and reset all picture and audio calibration settings.8h
