CVE-2026-59111Network attack vector

Command execution via unsanitized AppleScript argument concatenation

Published Aug 31, 2026 · Updated Aug 31, 2026

OS command injection in macOS eObčanka – Identifikace 3.5.1 and earlier allows remote attackers to execute commands via a crafted URL. The czeeopauth:// handler concatenates incoming URL parameters into a compiled AppleScript wrapper without sufficient sanitization, allowing quotes and shell expansions to escape the intended command context. Exploitation requires a logged-in user to click a crafted link, and commands run with that user's privileges.
