CVE-2026-31216
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 · uneditedThe nexent v1.7.5.2 backend service contains an unauthorized arbitrary storage file deletion vulnerability in its file management API. The DELETE /storage/{object_name:path} endpoint lacks authentication, authorization, and input validation mechanisms. Unauthenticated remote attackers can send crafted requests with a user-controlled object_name path parameter to delete arbitrary files from the underlying MinIO storage system. Successful exploitation leads to data loss and denial of service.
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 · high confidenceThe nexent v1.7.5.2 backend service has a critical authentication bypass vulnerability in its DELETE /storage/{object_name:path} endpoint. The API lacks authentication, authorization, and input validation, allowing unauthenticated remote attackers to manipulate the object_name path parameter to delete arbitrary files from the underlying MinIO storage system, causing data loss and denial of service.

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.
-
Identify installed Nexent versionCheck the installed version of Nexent Nexent using package manager, software inventory, or application version command (e.g., nexent --version, rpm -q nexent, or check installed packages)Affected if The installed version is exactly 1.7.5.2
-
Confirm DELETE /storage endpoint existsReview API documentation or network traffic logs to verify the DELETE /storage/{object_name:path} endpoint is exposed in the deploymentAffected if The endpoint is exposed and accessible to network clients
-
Verify authentication on storage deletion endpointInspect API configuration, web server settings, or proxy rules to determine if authentication is enforced on the DELETE /storage endpointAffected if Authentication is NOT configured or is bypassed for this endpoint
-
Check for path traversal protectionsReview API security settings, input validation rules, or web application firewall (WAF) configuration to see if path traversal prevention exists for the object_name parameterAffected if No input validation or path traversal guards are in place for the object_name parameter
-
Test endpoint accessibility from unauthenticated perspectiveIf authorized for security assessment, send a minimal DELETE request to /storage/testpath (using a non-destructive path) from an unauthenticated context to verify the endpoint accepts requests without credentialsAffected if The endpoint processes requests without requiring authentication credentials
Your environment is affected if you are running Nexent version 1.7.5.2 and the DELETE /storage endpoint is accessible without authentication.

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.
From vendor dataImplement authentication and authorization checks on the DELETE endpoint, add strict input validation to prevent path traversal, and enforce allowlist-based file deletion policies to restrict which files can be deleted.
