CVE-2026-42737
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 e4jvikwp VikBooking Hotel Booking Engine & PMS vikbooking allows Path Traversal.This issue affects VikBooking Hotel Booking Engine & PMS: from n/a through <= 1.8.9.
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 confidenceA path traversal vulnerability exists in VikBooking Hotel Booking Engine & PMS (versions through 1.8.9) that allows attackers to access files outside the restricted web root directory through manipulation of file path inputs, potentially exposing sensitive system files.

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 VikBooking installationLocate the VikBooking installation directory on the web server. Typical locations include /var/www/html/, /home/*/public_html/, or C:\inetpub\wwwroot\ depending on the server OS. Look for directories or files containing 'vikbooking' or 'vik' in the name.Affected if VikBooking software is present on the server
-
Determine installed versionAccess the VikBooking admin panel and navigate to the About or System Information page to view the software version. Alternatively, check version.php or similar version files within the installation directory if accessible.Affected if The installed version is 1.8.9 or earlier (any version 'through 1.8.9')
-
Identify file handling functionalityReview the VikBooking application for features that accept file path inputs, such as file upload/download, backup/restore, template editing, or image management modules. These are typical entry points for path traversal.Affected if The application processes user-supplied file paths in any functionality
-
Test for path traversal vulnerabilityIf file path parameters are identified, examine the code or test the parameter values with sequences like ../../ to see if the application permits access to directories outside the web root. Use a controlled request to a known file outside the VikBooking directory.Affected if The application allows .. sequences in file path parameters to access files outside the intended directory
A user is affected if VikBooking Hotel Booking Engine is installed and the installed version is 1.8.9 or earlier, and the application exposes any functionality that processes file path inputs without proper 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 input validation with canonicalization to resolve paths and verify they resolve within allowed directories, preventing '..' sequences and absolute path traversal attempts.
