Skullcandy Dime 3 earbuds expose users to Bluetooth hijacking

CERT/CC warns Skullcandy Dime 3 earbuds accept silent Bluetooth pairings via CVE-2025-20701, letting nearby attackers hijack audio and microphone.

CERT/CC reports the Skullcandy Dime 3 (model S2DCW) running firmware 1.0.0.28 is affected by CVE-2025-20701, a high-severity missing-authentication flaw in the Airoha Bluetooth Audio SDK. An attacker in close range can pair without user interaction, then hijack audio playback, access the headset profile, and capture live microphone audio. Skullcandy fixed the issue in firmware 1.0.0.30, but existing units have no consumer-accessible update path via the app. The flaw was discovered by ERNW researchers and affects earbud and headphone products from multiple vendors; Apple patched it for Beats Studio Buds in June.

Marimo Notebook Flaw Could Run MCP Commands Before Cells Execute in Edit Mode

Marimo notebook flaw CVE-2026-75149 (CVSS 8.7) allows attacker-supplied MCP commands to run as local subprocesses before any cell executes in edit mode.

Marimo addressed CVE-2026-75149, a high-severity code injection flaw allowing attacker-supplied Model Context Protocol (MCP) commands to execute as local subprocesses when a crafted notebook is opened in edit mode, before any cell runs. The issue affects versions prior to 0.23.15, carries CVSS v4 of 8.7 and CVSS v3.1 of 8.8, and requires user interaction but no authentication. Marimo fixed it in version 0.23.15 (released July 23, 2026) via a PEP 723 hardening patch that treats notebook metadata as attacker-controlled and strips ai, mcp, completion, secrets, and server configuration sections. VulnCheck's CNA also disclosed CVE-2026-67618 (CVSS 7.1), involving an attacker-controlled AI base_url that exfiltrates operator API keys, and earlier CVE-2023-39987, a missing auth on /terminal/ws endpoint allowing full PTY shell access.
