Security readout for executives and security teams
Plain-English summary
CVE-2025-31403 is a critical SQL injection issue in the WordPress Booking Calendar and Notification plugin up to version 4.0.3. An attacker may be able to query backend database information without logging in. The sources do not state a patched version, exploit details, or active exploitation.
Executive priority
Treat this as urgent for any public WordPress site using the affected plugin. The main business risk is unauthorized database access from an unauthenticated attacker. First determine whether the plugin is installed, then apply vendor-supported remediation or remove the exposure until guidance is confirmed.
Technical view
The issue is CWE-89 blind SQL injection in shiptrack Booking Calendar and Notification, package booking-calendar-and-notification, affecting versions through 4.0.3. CVSS 3.1 is 9.3: network reachable, low complexity, no privileges, no user interaction, scope changed, high confidentiality impact, and low availability impact.
Likely exposure
Public WordPress sites using Booking Calendar and Notification version 4.0.3 or earlier are the relevant exposure. Internet-facing booking forms or plugin routes should be treated as higher risk, but the source bundle does not name the vulnerable endpoint or parameter.
Exploitation context
The CVE is not listed as KEV in the supplied bundle, and the sources provided do not support a claim of active exploitation. The CVSS vector indicates unauthenticated network exploitation is possible, but no proof-of-concept or attack telemetry is included.
Researcher notes
Evidence is limited to CVE and Patchstack-style advisory data. The bundle does not include vulnerable parameter details, fixed version, patch diff, exploit code, or exploitation telemetry. Do not infer affected forks, alternate plugins, or confirmed exploitation beyond the provided sources.
Mitigation direction
- Inventory WordPress sites for booking-calendar-and-notification plugin usage and version.
- Prioritize sites running Booking Calendar and Notification version 4.0.3 or earlier.
- Check vendor or Patchstack guidance for a fixed release before upgrading.
- If no fixed release is available, consider disabling or removing the plugin.
- Review database and web logs for unusual plugin-related request patterns.
Validation and detection
- Confirm plugin slug and installed version from WordPress administration or asset inventory.
- Verify whether affected sites are internet-facing and reachable by unauthenticated users.
- Check authoritative vendor or Patchstack notes for patch availability and remediation instructions.
- Review WAF, web server, and application logs for suspicious database-error or probing patterns.
- Document whether compensating controls cover the affected WordPress routes.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
