Oracle has released a Critical Security Patch Update in June 2026 that includes patches addressing CVE-2026-46861. Customers are strongly advised to apply these security patches as soon as possible. Until patches are applied, risk can be partially mitigated by blocking network protocols required for the attack and by removing unnecessary privileges from users who do not need them. However, these mitigations may disrupt application functionality. Oracle recommends remaining on actively supported versions and applying patches without delay. Patch status is confirmed by the vendor advisory, indicating an official fix is available.
