NeMo Speech: Improper Neutralization of Special Elements used in a Command
CVE-2026-65111 is a high-severity improper neutralization of special elements used in a command vulnerability in NeMo Speech from NVIDIA, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. Affected NeMo Speech versions: 0.0 to 2.9. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.25% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
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.

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
