CVE-2025-13968: Starboard Suite Reservation Calendars <= 3.1.4 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes

The Starboard Suite Reservation Calendars plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcode attributes in the [starboard-suite-lightbox] shortcode in all versions up to, and including, 3.1.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Security readout for executives and security teams

Plain-English summary

This is a stored XSS issue in a WordPress reservation-calendar plugin. A logged-in user with Contributor-level access or higher could place malicious script content through a plugin shortcode, causing it to run when someone views the affected page. The business risk is moderate and depends on who has posting rights.

Executive priority

Treat as a moderate-priority WordPress content-integrity risk. Prioritize sites with many content contributors, public logins, agencies, contractors, or shared editorial workflows.

Technical view

CVE-2025-13968 affects Starboard Suite Reservation Calendars up to and including 3.1.4. The [starboard-suite-lightbox] shortcode does not sufficiently sanitize attributes or escape output, enabling authenticated Contributor+ stored cross-site scripting. It is classified as CWE-79 with CVSS 3.1 score 6.4.

Likely exposure

Exposure is likely limited to WordPress sites running this plugin at version 3.1.4 or earlier, especially where Contributors, Authors, Editors, or Administrators can create shortcode content.

Exploitation context

The source bundle does not show KEV listing or evidence of active exploitation. Abuse requires authenticated access with Contributor-level permissions or higher, then a victim viewing an affected page where injected script content is stored.

Researcher notes

Evidence identifies the affected shortcode and inadequate sanitization/output escaping, but the bundle does not provide exploit telemetry or a named fixed version. Use vendor and Wordfence updates to confirm remediation status before closing findings.

Mitigation direction

  • Inventory WordPress sites using Starboard Suite Reservation Calendars.
  • Upgrade to a fixed release if vendor guidance identifies one.
  • Restrict Contributor-level and higher access to trusted users only.
  • Review and remove suspicious [starboard-suite-lightbox] shortcode content.
  • Monitor Wordfence and WordPress plugin guidance for remediation details.

Validation and detection

  • Check installed plugin versions against 3.1.4 and earlier.
  • Review posts and pages containing [starboard-suite-lightbox].
  • Audit users with Contributor, Author, Editor, or Administrator roles.
  • Review recent content changes by lower-privileged authenticated users.
  • Confirm shortcode output is sanitized after remediation.
