Homebrew 7.0.0 is out, here’s what changed for security
Homebrew 7.0.0 closes eight security advisories, including a High sudo execution bug fixed in 6.0.12, and ships brew vulns vulnerability scanning.
Homebrew 7.0.0 closes eight security advisories rated one High, two Moderate, and five Low. The High flaw let unsigned cask removal metadata execute commands with sudo (fixed in 6.0.12), while the 7.0.0 Moderate closes a LaunchServices escape that let a malicious cask execute code outside the macOS install sandbox. The release ships brew vulns, which checks installed formulae against OSV.dev, extends build attestation verification to third-party tap bottles, and replaces Bubblewrap with Landlock sandboxing on Linux.

Hack One Robot, Reach the Next: Unitree G1 Security Flaws
Researcher chained two Unitree G1 flaws (CVE-2026-76639, CVE-2026-76640) to gain unauthenticated root access, with compromised robots able to infect others via Bluetooth.
Security researcher Olivier Laflamme chained a path-traversal file-write flaw (CVE-2026-76639) in the G1 chatbot service and a Bluetooth server buffer overflow (CVE-2026-76640) to achieve unauthenticated root access remotely. The chain abuses Unitree's cloud API as a decryption oracle for the AES-128 key that unlocks BLE and WebRTC channels, and a compromised robot can propagate the attack to nearby G1 units. Unitree patched the cloud ownership-check flaw, paid a $5,000 bounty, and firmware fixes for BLE pairing and the buffer overflow remain harder to deliver.
