——10Shinobi before commit 5a76c74f contains a hardcoded connection key in the child node service that allows unauthenticated attackers to execute arbitrary database queries. Attackers reaching the child node port can present the hardcoded key during WebSocket handshake, then dispatch SQL queries through the onWebSocketDataFromChildNode handler to read and modify user records and camera configuration.2d CVE-2026-19412—

——3This vulnerability exists in the CP Plus CP-XR-DE21-S Router due to the presence of hardcoded HTTP Digest authentication credentials in the firmware that are identical across all devices running the affected firmware. An attacker with access to the local network could exploit this vulnerability by obtaining the hardcoded authentication information from the firmware. Successful exploitation of this vulnerability could allow the attacker to gain unauthorized administrative access and perform privileged operations on the targeted device.2d CVE-2026-13086—

——10DJI drones contain an FTP service that uses hardcoded credentials shared across affected models and permits authenticated users to upload files without limits on file size, file count, or total storage consumed in **/blackbox/upgrade/**, as well as overwrite existing files in that directory. An attacker with access to the drone's internal network or USB RNDIS interface can exhaust the available storage, preventing the aircraft from writing flight records, logs, and telemetry and potentially preventing subsequent firmware updates. Uploaded files persist across reboot and factory reset. 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.3d CVE-2026-758969.1 CRI
