DescriptionCVE.org
NVIDIA NeMo Framework contains a vulnerability where a user could cause a deserialization of untrusted data by remote code execution. A successful exploit of this vulnerability might lead to code execution and data tampering.
Executive ViewAI
Organizations using NVIDIA NeMo Framework face notable risk from CVE-2025-23249, a insecure deserialization vulnerability rated CVSS 7.6. Insecure deserialization could allow attackers to execute arbitrary code by providing crafted serialized data. Organizations should apply vendor updates when available and consider compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Restrict deserialization endpoints; (2) Implement integrity checks on serialized data; (3) Use type-safe alternatives.

SSVC AssessmentENISA
Priority Score
Attack Technique
Insecure deserialization occurs when an application converts serialized data (a stream of bytes representing an object's state) back into a living object without proper validation.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
