Descripción técnica

Cudy WR3000 2.0 running firmware before 2.5.24 contains a hard-coded JWT HMAC signing secret vulnerability in the Mosquitto MQTT broker's authentication plugin that allows unauthenticated attackers to forge valid JWT tokens by extracting the secret from the firmware image. Attackers can use the extracted secret to craft arbitrary JWT tokens and authenticate to the MQTT broker without legitimate credentials, gaining unauthorized access to the device's mesh networking interface.

——0In Splunk AI Toolkit versions below 6.0.0, a user who does not hold the "admin" or "power" Splunk roles could obtain predictable or default credentials for connected container services. The use of hard-coded credentials is possible because Splunk AI Toolkit generates or stores credentials for connected container services using predictable or hard-coded default values. For more information see Connections tab in the AI Toolkit (https://help.splunk.com/en/splunk-cloud-platform/apply-machine-learning/use-ai-toolkit/5.7.2/ai-toolkit-commands-macros-and-visualizations/connections-tab-in-the-ai-toolkit) in the Splunk documentation.12h CVE-2026-748938.8 ALT

——5A security vulnerability has been identified in the Planet9 desktop application where a hardcoded read-only API key permitted unauthorized access to internal repositories. An attacker could exploit this access to extract embedded administrative keys and secrets, potentially allowing them to gain administrative access to repository infrastructure and modify software source code. To mitigate this security risk, Acer has released an update to resolve the issue.3d CVE-2026-199018.1 ALT
