Published Feb 11, 2026 · Updated Feb 11, 2026
Out-of-bounds read in QNAP Qsync Central 5.0.x before 5.0.0.4 allows remote authenticated users to obtain secret data. QNAP identifies the flaw only as an out-of-bounds memory read and does not disclose the affected component, input, or faulty bounds operation. Access to a Qsync Central user account is required; the documented consequence is disclosure of secret data, with no integrity or availability impact reported.
