NVIDIA has issued a essential safety bulletin addressing a high-severity vulnerability in its NeMo Curator platform that would permit attackers to execute malicious code and escalate privileges on affected programs.
The vulnerability, designated CVE-2025-23307, impacts all variations of NVIDIA NeMo Curator previous to launch 25.07 throughout Home windows, Linux, and macOS platforms.
The safety flaw stems from improper enter validation within the NeMo Curator’s file processing mechanisms, enabling risk actors to craft malicious recordsdata that set off code injection assaults.
Key Takeaways1. CVE-2025-23307 in NeMo Curator permits native code execution and privilege escalation.2. Improper enter validation impacts confidentiality, integrity, and availability.3. Improve and tighten entry controls.
With a CVSS v3.1 base rating of seven.8, this vulnerability is assessed as excessive severity and poses important dangers to enterprise AI infrastructure deployments.
Code Injection Vulnerability
The vulnerability is categorized underneath CWE-94 (Code Injection), indicating that the NeMo Curator fails to correctly sanitize user-supplied enter when processing sure file sorts.
The assault vector requires native entry (AV:L) with low assault complexity (AC:L) and low privileges (PR:L), making it comparatively accessible to attackers who’ve gained preliminary system entry.
The CVSS vector string AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H reveals that profitable exploitation requires no person interplay (UI:N) and can lead to excessive impression to confidentiality, integrity, and availability.
Attackers can doubtlessly obtain full system compromise by code execution, privilege escalation, info disclosure, and knowledge tampering capabilities.
The corporate emphasizes that native entry necessities could restrict the vulnerability’s instant exploitability in correctly segmented environments.
The vulnerability was responsibly disclosed to NVIDIA by safety researcher D.Okay., highlighting the significance of collaborative safety analysis in figuring out and addressing AI platform vulnerabilities.

Mitigations
NVIDIA has launched Curator model 25.07 to deal with this safety vulnerability, with updates out there by the official NVIDIA GitHub repository.
Organizations utilizing earlier department releases are suggested to improve to the newest out there model inside their deployment department, as all historic variations stay affected by this vulnerability.
The safety replace implements enhanced enter validation mechanisms and file processing safeguards to stop malicious code injection assaults.
System directors ought to prioritize this replace, significantly in environments the place NeMo Curator processes untrusted or exterior knowledge sources.
NVIDIA recommends conducting thorough testing of the up to date model in staging environments earlier than manufacturing deployment to make sure compatibility with present AI workflows and mannequin coaching pipelines.
Organizations must also evaluate their entry management insurance policies to attenuate potential assault surfaces, given the vulnerability’s native entry necessities.
