Severity by source
AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Local vector and low privilege because the toolkit must locally process attacker input from a low-priv context; command injection yields full C/I/A impact within an unchanged scope.

NVIDIA NeMo Speech for all platforms contains a vulnerability where malicious input created by an attacker could cause a code injection. A successful exploit of this vulnerability might lead to code execution, information disclosure, and data tampering.
Articles & Coverage 1
AnalysisAI
Code injection in NVIDIA NeMo Speech versions 0.0 through 2.9 allows local attackers with low privileges to execute arbitrary code, disclose sensitive information, and tamper with data by supplying crafted input to the toolkit. The vulnerability requires local access (AV:L) and low privileges (PR:L) but no user interaction; it has a CVSS 3.1 base score of 7.8 (High) and is classified as CWE-77 (command injection). …

Vulnerability AssessmentAI
| Exploitation | Requires local access to a host running NVIDIA NeMo Speech (AV:L) with at least low-privileged access (PR:L), and the NeMo Speech toolkit must process attacker-crafted malicious input that reaches the vulnerable command/code-injection sink (CWE-77). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-assigned CVSS 3.1 base score is 7.8 (High) with vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H - a LOCAL attack vector requiring low privileges but no user interaction, yielding full confidentiality, integrity, and availability impact via CWE-77 code/command injection. … 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 | Apply the patch or mitigation specified in NVIDIA's product security advisory at https://github.com/NVIDIA/product-security/tree/main/2026/5885, and upgrade NeMo Speech to a fixed version once identified by the vendor. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every host, container image, and CI/CD runner where NVIDIA NeMo Speech versions 0.0 through 2.9 are installed, confirm exposure with the vendor advisory at GitHub NVIDIA product-security 2026/5885, and restrict local shell and interactive access on those systems to the minimum set of trusted operators; where the toolkit is not in active use, remove or disable the package entirely. …
