Fusion: Initialization of a Resource with an Insecure Default
CVE-2025-36222 is a critical-severity initialization of a resource with an insecure default vulnerability in Fusion from IBM, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Fusion versions: 2.2.0 through 2.10.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.39% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Storage Fusion to 2.11.0 or a later version.
- Update Storage Fusion Hci to 2.11.0 or a later version.
- Update Storage Fusion Hci For Watsonx to 2.11.0 or a later version.
- Read the advisory on ibm.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
