CVE-2024-31404Network attack vector

Authenticated Scheduler data disclosure via access-control bypass

Published Jun 11, 2024 · Updated Nov 21, 2024

Sensitive-data exposure in Cybozu Garoon 5.5.0 through 6.0.0 allows remote authenticated users to view restricted Scheduler data. The Scheduler response exposes records without enforcing the requesting account's viewing restrictions, although Cybozu has not published the request path or flawed routine. A valid product account is required; the documented consequence is read-only exposure of Scheduler data, with no integrity or availability impact.
