CVE-2026-59111
CriticalCVSS 9.3Summary
An OS command injection vulnerability in the eObčanka-Identifikace application (DIA) on MacOS allows an attacker to register a custom URL scheme (czeeopauth://) for parameterized application execution. Prior to version 3.6.0, incoming URL parameters were passed to the compiled AppleScript wrapper using concatenation without sufficient sanitization.
Risk Assessment
An attacker can execute arbitrary system commands on the victim's computer, potentially leading to full system compromise.
Recommendation
Update the eObčanka-Identifikace application to version 3.6.0 or later, which includes a fix. Avoid opening suspicious links with the custom URL scheme.
