AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Remote unauthenticated authentication bypass (AV:N/AC:L/PR:N/UI:N) granting full read, write, and DoS over stored data justifies C:H/I:H/A:H; scope unchanged as impact stays within the storage service.

1DescriptionCVE.org
NVIDIA AIStore framework contains a vulnerability where an attacker could bypass authentication. A successful exploit of this vulnerability might lead to denial of service, escalation of privileges, information disclosure, and data tampering.
Articles & Coverage 2
AnalysisAI
Authentication bypass in NVIDIA AIStore, a scalable distributed object-storage framework for AI/ML data pipelines, lets a remote attacker circumvent access controls (CWE-290) and reach protected functionality without valid credentials. Because the flaw yields full confidentiality, integrity, and availability impact (CVSS 9.8), successful exploitation can enable information disclosure of stored datasets, tampering with training data, privilege escalation, and denial of service. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network access to an exposed AIStore API endpoint (proxy/gateway or target node) that performs the flawed authentication check; per the CVSS vector AV:N/AC:L/PR:N/UI:N, no credentials, user interaction, or elevated privileges are needed against affected configurations. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are consistent toward high priority: the CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H describes remote, low-complexity, unauthenticated exploitation with total impact, and an authentication-bypass root cause aligns cleanly with PR:N. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with network reach to an AIStore cluster's API sends crafted requests that defeat the identity check, gaining unauthorized access as if authenticated. From there they enumerate and exfiltrate stored training datasets (information disclosure), overwrite or poison objects (data tampering/integrity), or overwhelm/misconfigure the cluster to cause denial of service. … |
| Remediation | Consult the NVIDIA product-security advisory at https://github.com/NVIDIA/product-security/tree/main/2026/5849 and upgrade AIStore to the fixed release identified there; no vendor-released patch version was independently confirmed in the available data, so the advisory is the authoritative source for the exact fixed build. … Detailed patch versions, workarounds, and compensating controls in full report. |
