Denial of service in Meshtastic firmware prior to 2.7.23.b246bcd allows a single node whose User.long_name contains malformed UTF-8 to render other radios unmanageable over Bluetooth Low Energy when paired with the iOS app. Because the strict-parsing iOS client refuses to load a node database containing a poisoned entry, BLE sync enters a fail/retry loop and the operator loses control of the device; the malformed name propagates across the mesh, so one bad node can degrade iOS management for many users over a wide area. There is no public exploit identified at time of analysis, but the condition has been observed occurring naturally in the wild from ordinary buffer truncation rather than deliberate attack.
Poisoned-pipeline (pwn request) code execution in the Meshtastic firmware repository's GitHub Actions CI allows any external user to run arbitrary code inside the project's trusted CI context prior to firmware 2.7.21.1370b23. Because main_matrix.yml (and related workflows) triggered on pull_request_target while the check, build, and build-debian-src jobs checked out and executed code from the attacker's fork with no approval gate, a pull request from an author_association of NONE automatically ran attacker-controlled files with access to repository secrets and an elevated GITHUB_TOKEN. This is CWE-94 code injection scoring CVSS 10.0; no public exploit identified at time of analysis, though a linked Google Drive writeup may contain proof-of-concept detail.
Authentication bypass in Tenda router firmware (AC10, AC5, AC6, FH1201, W15E) lets any user log in as administrator via a hidden vendor backdoor: after normal MD5-based login fails, the /bin/httpd login() routine at 0x4c88b8 falls back to a plaintext strcmp() against the 'sys.rzadmin.password' config value, granting role=2 (admin) with any username. Reported through CERT/CC (VU#213560), it is not in CISA KEV and has no public exploit identified at time of analysis, with a low EPSS score of 0.24% (15th percentile). The flaw is a classic CWE-912 hidden-functionality backdoor mapped to CVSS 9.8.
Anonymous MQTT access in Yarbo firmware v2.3.9 allows remote unauthenticated attackers on the local network to fully control the robotic lawn mower and exfiltrate sensitive telemetry data. The embedded MQTT broker accepts connections without credentials and enforces no topic-level access controls, enabling arbitrary publish/subscribe operations. No authentication, authorization, or message validation occurs. EPSS and KEV data not available; exploitation requires only network access to the robot's MQTT port (typically TCP 1883).
Hardcoded administrative credentials in Yarbo firmware v2.3.9 allow remote unauthenticated attackers to gain full device administrative access across all deployed units. The CVSS 9.8 critical score reflects the complete lack of authentication barriers (AV:N/AC:L/PR:N), with identical credentials embedded in every device that cannot be changed by end users. No active exploitation has been confirmed by CISA KEV, but a public GitHub repository reference suggests potential proof-of-concept availability. EPSS data unavailable, though the trivial exploitation path (no complexity, no privileges required) indicates high weaponization potential once credentials become widely known.
Undocumented persistent backdoor in Yarbo firmware v2.3.9 grants remote privileged access that survives factory reset and firmware updates. The backdoor requires high-privilege authentication (CVSS PR:H) but provides complete system control once accessed. No public exploit identified at time of analysis, though GitHub repository reference suggests technical disclosure exists. CVSS 7.2 reflects the high-privilege requirement, but persistence across resets and undocumented nature indicate significant supply chain or insider threat risk.
