CVE-2026-24204
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNVIDIA Flare SDK contains a vulnerability where an Attacker may cause an Improper Input Validation by path traversing. A successful exploit of this vulnerability may lead to information disclosure.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNVIDIA Flare SDK has an improper input validation vulnerability where path traversal allows attackers to access files outside intended directories through specially crafted input, potentially exposing sensitive information.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm NVIDIA Flare SDK installationRun 'pip show nvflare' or check for the nvflare package in your Python environmentAffected if The package is not installed or not present in the environment
-
Determine installed Nvflare versionRun 'pip show nvflare' and note the Version field, or check your requirements.txt/project dependenciesAffected if The installed version is lower than 2.7.2 (e.g., 2.7.1, 2.6.0, etc.)
-
Identify exposed file operation endpointsReview API endpoints or services that handle file paths as input, particularly those involved in file transfer, storage, or processing workflowsAffected if The system exposes any file operation interfaces that accept path inputs from users or external sources
-
Inspect file handling configurationsCheck job configurations, executor settings, and any custom components that process file paths for the presence of path traversal validationAffected if File path inputs are processed without validation for '..' sequences or absolute path patterns
You are affected if NVIDIA Flare SDK is installed with a version lower than 2.7.2 AND your environment exposes file operations that accept user-supplied path inputs without validation.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.7.2
Implement strict input validation and path sanitization for all file operations, using allowlists for permitted paths and rejecting paths containing traversal sequences (.. or /).
NVFLARE version 2.7.2
- 1. Identify all deployments of NVIDIA FLARE SDK in your environment
- 2. Check the current installed version of NVFLARE (e.g., via pip show nvflare or checking requirements files)
- 3. Upgrade to version 2.7.2 or later by running: pip install --upgrade nvflare>=2.7.2
- 4. Verify the upgrade was successful by checking the installed version
- 5. Test that critical path traversal operations in your FLARE workflows function correctly after the upgrade
