StorageGRID (formerly StorageGRID Webscale) versions 11.5 and higher in a non-standard configuration and scenario are susceptible to a Denial of Service vulnerability. Successful exploit could allow an attacker with some control over the environment to cause a partial Denial of Service.
CVE-2026-22056
This low-severity CVE scores 2.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 84% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
