CWE-306 26/08/2026
NebulaGraph through 3.8.0 Unauthenticated Read and Modification of Runtime Configuration
NebulaGraph exposes its runtime configuration over an unauthenticated HTTP service. Each daemon starts the web service defined in src/webservice/WebService.cpp, whose bind address defaults to all interfaces, and registers routes for reading and writing gflags alongside status and statistics. Neither the service nor its router carries any authentication, token check or address restriction. The read route returns the daemon's full set of runtime flag values, which includes the configured certificate, key and certificate-authority paths, the password file path, data directories and the transport-security enable flags. The write route parses a supplied map and applies each entry through the gflags runtime setter, so a caller able to reach the port can change the daemon's behaviour without restarting it, including disabling the transport-security flags, redirecting log files and altering flags such as failed_login_attempts and password_lock_time_in_secs. Public reports of this endpoint describe a single name, enable_authorize, being refused by the handler; at release 3.8.0 that refusal is not present and the handler applies every name it is given.

Nextcloud MCP Server: Unauthenticated `POST /webhooks/nextcloud` allows arbitrary vector data deletion when `WEBHOOK_SECRET` is unset ( default )
Nextcloud MCP Server is a production-ready MCP server that connects AI assistants to a Nextcloud instance. Prior to 0.117.2, the POST /webhooks/nextcloud endpoint in nextcloud_mcp_server/vector/webhook_receiver.py has no authentication by default because WEBHOOK_SECRET defaults to None and startup validation does not require it. When WEBHOOK_SECRET is unset, handle_nextcloud_webhook() accepts unauthenticated requests. The payload["user"]["uid"] field parsed in nextcloud_mcp_server/vector/webhook_parser.py is attacker-controlled and is used without an authenticated-session cross-check for Qdrant operations, allowing a network attacker to delete or trigger re-indexing of vector embeddings for any user and to destroy the semantic search index by sending forged deletion events. This issue is fixed in version 0.117.2.

rConfig Core 8.0.0 < 8.2.10 Unauthorized Admin Registration via web.php
rConfig Core 8.0.0 before 8.2.10 contains an authentication bypass vulnerability that allows unauthenticated attackers to self-register accounts with full Administrator privileges due to a duplicate bare Auth::routes() call in routes/web.php that re-enables the POST /register route after it was explicitly disabled. Attackers can register a new account that is immediately authenticated with Admin-level access because the registration controller does not assign a role and the users.role column defaults to Admin, enabling access to stored device credentials, user data, and API token issuance.

Missing Authentication Allows Unauthorized Creation of Crypto Groups in RansomLook
RansomLook contains a missing authentication vulnerability in the /admin/crypto/group/new endpoint. While the endpoint provides an administrative function for creating new crypto group entries, it was not protected by the application's authentication mechanism.
An unauthenticated remote attacker able to access the RansomLook web interface could therefore submit requests to this endpoint and create crypto group entries without possessing a valid authenticated session or administrative credentials.
Successful exploitation allows an attacker to make unauthorized modifications to data that should only be manageable by authenticated administrators. Depending on how crypto group information is subsequently consumed by RansomLook, malicious or fraudulent entries could also affect the integrity of information presented or processed by the application.
The vulnerability is addressed by applying the flask_login.login_required decorator to the /admin/crypto/group/new route, ensuring that only authenticated users can access the functionality.

DJI Drone Bluetooth Interface Unauthenticated DUML Command Execution
DJI drones expose an unauthenticated DUML command interface over Bluetooth that allows an attacker within Bluetooth range to modify Wi-Fi configuration parameters, including the SSID, PSK, MAC address, regulatory country code, and wireless channel. An attacker can overwrite the Wi-Fi PSK with a known value and connect to the drone's internal Wi-Fi network, potentially gaining access to the flight control interface and issuing flight commands. Crafted DUML commands can also disable or restart the Wi-Fi and Bluetooth interfaces, disconnect Wi-Fi clients, or reset wireless configuration, resulting in a denial-of-service condition that can disrupt the operator's wireless control, video, and telemetry connections during flight.
Affected models are DJI Neo until 01.00.0400, DJI Neo 2 until 01.00.0500, DJI Flip until 01.00.1200, DJI Air 3 until 01.00.1600, DJI Air 3S until 01.00.1400, DJI Avata 2 until 01.00.0400, DJI Avata 360 until 01.00.0300, DJI Mavic 3 until 01.00.1400, DJI Mavic 3 Classic until 01.00.0800, DJI Mavic 3 Pro until 01.01.0700, DJI Mavic 4 Pro until 01.00.0500, DJI Mini 2 until 01.07.0200, DJI Mini 3 until 01.00.0500, DJI Mini 3 Pro until 01.00.0900, DJI Mini 4 Pro until 01.00.1100, and DJI Mini 5 Pro until 01.00.0600.
Remediation requires a firmware update from the vendor.

AVideo Authentication Bypass via Unkeyed Video Hash Disclosure
AVideo through commit 9c39d8c8 contains an authentication bypass vulnerability where deduplicateByEncoderQueueId() returns video_id_hash credentials for any video by encoder_queue_id without ownership verification, and useVideoHashOrLogin() converts this hash into passwordless login as the video owner. Attackers with upload permission can retrieve an administrator's video_id_hash by omitting the videos_id parameter, then use that hash in an unauthenticated request to gain administrative session access and modify system configuration.

Arc Enterprise cluster replication accepts unauthenticated MsgReplicateSync messages, enabling cluster-wide data injection from any TLS-trusted peer
Arc is an open, SQL-native time-series database for telemetry. Prior to version 26.06.1, Arc Enterprise's cluster replication receiver at `internal/cluster/replication/receiver.go` validates only the wire-format envelope (length, opcode) of inbound messages. The `MsgReplicateSync` payload itself is accepted without any application-layer authentication — no HMAC, no signature, no per-message nonce. The replication stream is protected at the transport layer by TLS / mTLS, but there is no protection against application-layer message tampering or replay once a peer is on the cluster network. This is fixed in 2026.06.1. Some workarounds are available. Restrict cluster network access to known-trusted peers via strict firewall rules, audit replication logs for unexpected `MsgReplicateSync` traffic, and/or disable cluster mode until the fix is available.
