CVE-2026-108721

Open Computer Use through 1.0.0 on macOS contains an improper case sensitivity handling vulnerability that allows local MCP callers to bypass the password-manager denylist using case-variant bundle identifiers. Attackers, including prompt-injected model turns, can pass identifiers like com.1Password.1Password to get_app_state and action tools to read accessibility trees, capture screenshots, and drive unlocked password manager interfaces.
