CVE-2025-26540
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 · uneditedImproper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in helloprint Helloprint helloprint allows Path Traversal.This issue affects Helloprint: from n/a through <= 2.0.7.
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 · low confidenceA path traversal vulnerability in Helloprint <= 2.0.7 allows attackers to access files outside the restricted web root directory by manipulating file path inputs with '../' sequences. This could enable unauthorized read access to sensitive system files, configuration data, or other application resources.

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 the installed Helloprint versionLocate the version file, composer.json, or application metadata that contains the current Helloprint version number. This is typically found in the application root directory or configuration files.Affected if The installed version is Helloprint 2.0.7 or any version lower than 2.0.7 (e.g., 2.0.6, 2.0.5, 1.x)
-
Verify file handling functionality existsInspect the application codebase for file access operations, particularly any endpoints or functions that accept file path parameters. Look for code that reads, includes, or serves files based on user input.Affected if The application contains file handling code that accepts path parameters from user input
-
Identify path input acceptance pointsSearch the codebase for functions, controllers, or API endpoints that accept file path parameters and pass them to file operations without proper validation. Focus on features like file display, file inclusion, or file retrieval.Affected if There are endpoints or functions that accept file path parameters directly from user requests
-
Check for absence of path traversal protectionReview the file handling code to determine if input validation includes checks for '../' sequences, path canonicalization, or directory bounds checking before performing file operations.Affected if The file handling code does not validate or sanitize path inputs to block '../' sequences
A user is affected if running Helloprint version 2.0.7 or lower with accessible file handling functionality that accepts user-supplied path parameters without proper traversal protection.

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 input validation and path canonicalization for all file access operations, ensuring paths resolve within allowed directories and reject sequences containing '../' or absolute path references.
