QNAP has released patched versions (5.5.6.4847 and later) to remediate this issue.

NULL pointer dereference vulnerability in QNAP File Station 5 that allows authenticated remote attackers to trigger a denial-of-service condition by crashing the application. The vulnerability affects File Station 5 versions prior to 5.5.6.4847, and while it requires valid user credentials (PR:N indicates no privileges required once authenticated), it has a CVSS score of 7.5 reflecting high availability impact. No indication of active exploitation in the wild or public POC is evident from the provided data.

CVE-2025-22484 is an unthrottled resource allocation vulnerability in Qnap File Station 5 that allows authenticated remote attackers to exhaust system resources and cause denial of service. An attacker with valid user credentials can exploit this CWE-770 weakness to prevent legitimate users and processes from accessing shared resources, affecting availability. The vulnerability has a moderate-to-high CVSS 7.1 score driven by network accessibility and high availability impact, though it requires prior authentication; the fix is available in File Station 5 version 5.5.6.4847 and later.
