A path traversal vulnerability has been reported to affect several QNAP operating system versions. If a remote attacker gains an administrator account, they can then exploit the vulnerability to read the contents of unexpected files or system data. We have already fixed the vulnerability in the following versions: QTS 5.2.8.3332 build 20251128 and later QuTS hero h5.2.8.3321 build 20251117 and later QuTS hero h5.3.2.3354 build 20251225 and later
