Working Time Account: Exported component allows forged holiday entries
The holiday import component (feiertage.ImportActivity) of the Android app Working Time Account (Arbeitszeiterfassung2) is exported and requires no permissions. A zero-permission app installed on the same device can send crafted ICS data to it, which writes forged holiday entries into the app's work-time database without user interaction. The CVE data lists CVSS 8.8, but the research notes found conflicting scores (VulDB 3.5), so the severity is not yet verified; the impact is limited to integrity of time records.
