Security readout for executives and security teams
Plain-English summary
This vulnerability affects the WordPress VikBooking Hotel Booking Engine & PMS plugin version 1.5.3 and earlier. An unauthenticated attacker could upload a dangerous file through the booking form signature feature and potentially take control of the website. Compromised hotel booking sites could expose customer data, deface pages, or be used for further attacks.
Executive priority
Prioritize within the emergency remediation queue for any internet-facing hotel booking site using this plugin. The business risk is full website compromise and potential customer data exposure. If the plugin is present and vulnerable, reduce exposure immediately while confirming the vendor-supported fix.
Technical view
CVE-2022-27862 is a CWE-434 arbitrary file upload issue in E4J VikBooking for WordPress <=1.5.3. The source bundle describes upload and execution of dangerous file types through the booking form signature upload path. CVSS 3.1 is 9.8: network reachable, low complexity, no privileges, no user interaction, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress sites running the VikBooking Hotel Booking Engine & PMS plugin at version 1.5.3 or earlier, especially where public booking forms are enabled. The source bundle does not identify affected non-WordPress products or specific hosted-service exposure.
Exploitation context
The sources support remote code execution potential from arbitrary file upload. CISA KEV status is false in the bundle, and no provided source confirms active exploitation. Treat internet-facing vulnerable booking sites as high urgency because the CVSS vector requires no authentication or user interaction.
Researcher notes
Evidence is strong on affected product, affected version range, weakness class, and severity. Evidence is incomplete on fixed version, observed exploitation, and detailed vendor remediation in the supplied bundle. Avoid assuming exploit-in-the-wild status without KEV or another cited source.
Mitigation direction
- Inventory all WordPress sites for VikBooking plugin version 1.5.3 or earlier.
- Check vendor and Patchstack guidance for the fixed version before updating.
- If no fix is confirmed, temporarily disable the plugin or affected booking form.
- Prevent script execution from upload directories where operationally feasible.
- Review and remove unexpected uploaded executable files after containment.
Validation and detection
- Confirm installed VikBooking versions across production, staging, and backups.
- Verify public booking forms are not accepting dangerous executable uploads.
- Review web and WordPress logs for suspicious upload activity.
- Check site files for unexpected executable content in upload-accessible paths.
- Re-test after remediation to confirm the vulnerable upload path is closed.
