Vulnetix · Advisory published June 11, 2026

The Arch User Repository (AUR) package `mcp-probe` was identified as malicious during the June 2026 AUR supply-chain compromise, in which an attacker pushed backdoored PKGBUILDs to roughly 1,900 packages. Building or installing the affected package executed attacker-controlled code. The malicious revision has since been removed from the AUR.
