Description

CERT Polska has received a report about vulnerability in WEBCON BPS software and participated in coordination of its disclosure.

The vulnerability CVE-2026-92419: WEBCON BPS is vulnerable to Insecure Direct Object Reference (IDOR) in the /api/vacations/{path} endpoint. The selectedPeople parameter in the Gantt vacation chart API does not validate whether the requesting user is authorized to access the requested users' data. An authenticated attacker can supply arbitrary user logins in the selectedPeople parameter to view vacation schedules of other employees, including managers and staff from other offices, regardless of business logic access restrictions, resulting in unauthorized disclosure of sensitive scheduling information.

This vulnerability was fixed in versions: 2025.2.1.177 and 2026.1.1.20
