CVE-2025-67623
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 · uneditedServer-Side Request Forgery (SSRF) vulnerability in 6Storage 6Storage Rentals 6storage-rentals allows Server Side Request Forgery.This issue affects 6Storage Rentals: from n/a through <= 2.22.0.
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 confidenceServer-Side Request Forgery (SSRF) vulnerability in 6Storage Rentals version 2.22.0 and earlier allows attackers to induce the server to make arbitrary requests to internal or external resources, potentially accessing internal services, metadata endpoints, or bypassing network restrictions.

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 version of 6Storage RentalsLocate the software version information in the application admin panel, about page, or check version files in the installation directory. Compare against version 2.22.0 and earlier.Affected if The installed version is 2.22.0 or any earlier version.
-
Locate URL input functionalitySearch the application for features that accept URLs as user input, such as: external resource linking, URL preview features, webhook configuration, API endpoints accepting URLs, or any form field that accepts a web address.Affected if The application contains any feature that processes user-supplied URLs without strict allowlist validation.
-
Inspect URL handling codeReview the backend code that processes the URL input to determine if it performs server-side requests to the provided URL. Look for functions that make HTTP requests using user-supplied URLs.Affected if The application makes server-side requests to user-supplied URLs without proper validation.
-
Check for SSRF protectionExamine the application's URL validation logic to determine if it implements allowlist-based validation, disables dangerous protocols (file://, gopher://, etc.), or restricts access to internal network addresses.Affected if No strict allowlist validation is implemented or dangerous URL protocols are not blocked.
A user is affected if they are running 6Storage Rentals version 2.22.0 or earlier AND the application has a feature that accepts user-supplied URLs for server-side processing without strict allowlist validation.

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 strict allowlist-based validation for user-supplied URLs, disable unnecessary URL protocols, and enforce proper network segmentation to prevent internal resource access.
