Lifecycle Timeline
2DescriptionCVE.org
NVIDIA OpenShell for Linux contains a vulnerability in its inference proxy, where an attacker could cause an improper encoding or escaping of output. A successful exploit of this vulnerability might lead to information disclosure and data tampering.
AnalysisAI
Improper output encoding in NVIDIA OpenShell's inference proxy on Linux allows a local low-privileged attacker to cause information disclosure and data tampering across component boundaries. The CVSS scope-change flag (S:C) indicates impact extending beyond the vulnerable component itself, suggesting the inference proxy mediates data between trust zones. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local account on a Linux host with NVIDIA OpenShell installed and the inference proxy actively running (AV:L, PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.2 Medium rating is driven by AV:L (local access required), PR:L (low-privilege account sufficient), AC:L (low attack complexity), and S:C (scope change), with C:L and I:L reflecting limited but real confidentiality and integrity impact and no availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult the NVIDIA product security advisory at https://github.com/NVIDIA/product-security/tree/main/2026/5872 for patch version details - no specific fix version is confirmed in the available source data. … Detailed patch versions, workarounds, and compensating controls in full report. |
