Security readout for executives and security teams
Plain-English summary
CVE-2015-10099 is a SQL injection issue in the WordPress CP Appointment Calendar Plugin versions 1.1.0 through 1.1.5. A flaw in appointment processing can let a remote authenticated attacker affect database confidentiality, integrity, and availability. The provided sources name a patch commit but do not confirm active exploitation.
Executive priority
Prioritize remediation for public WordPress sites using this plugin, especially where many users can authenticate. The issue is database-facing and remotely reachable, but the provided evidence suggests authenticated access is required and does not show known exploitation.
Technical view
The vulnerable code is dex_process_ready_to_go_appointment in dex_appointments.php. Manipulation of the itemnumber argument leads to CWE-89 SQL injection. CVSS v2 is 6.5 with network access, low complexity, and single authentication required. The patch reference is commit e29a9cdbcb0f37d887dd302a05b9e8bf213da01d.
Likely exposure
Exposure is limited to WordPress sites running CP Appointment Calendar Plugin 1.1.0 through 1.1.5. Internet-facing sites with authenticated user paths into appointment processing are the primary concern. The bundle does not identify other affected products or fixed release numbers.
Exploitation context
The source bundle says the attack can be initiated remotely, but CVSS indicates authentication is required. CVE is not marked KEV, and the provided sources do not state active exploitation. Treat exploit activity as unconfirmed.
Researcher notes
Focus assessment on affected plugin versions, the dex_process_ready_to_go_appointment function, and itemnumber input handling. Avoid assuming unauthenticated reachability without local route testing. The patch commit is the strongest remediation reference; the source bundle does not provide a fixed version mapping.
Mitigation direction
- Inventory WordPress sites for CP Appointment Calendar Plugin versions 1.1.0 through 1.1.5.
- Apply the referenced upstream patch commit or a vendor-supported fixed package if available.
- Disable or remove the plugin where timely patching is not possible.
- Review vendor guidance before relying on compensating controls.
Validation and detection
- Confirm plugin version and presence of dex_appointments.php on each WordPress site.
- Verify whether commit e29a9cdbcb0f37d887dd302a05b9e8bf213da01d is present.
- Review appointment-processing logs for unusual itemnumber handling or database errors.
- Check whether only trusted authenticated users can reach affected appointment flows.

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.
