CVE-2019-25551Public exploit

Local application crash via oversized Program Alerts input

Published Mar 21, 2026 · Updated Mar 21, 2026

Denial of service in Sandboxie 5.30 allows local users to crash Sandboxie Control through an oversized Program Alerts entry. The Program Alerts dialog accepts a 5,000-character string in the “Select or enter a program” field and crashes after the entry is confirmed. Access to the local configuration interface is required, and the demonstrated consequence is an application crash rather than host compromise.
