1.6.9.29
CVE-2026-39493 affects the Appointment Booking Calendar — Simply Schedule Appointments Booking Plugin for WordPress. This vulnerability stems from insufficient input sanitization, allowing attackers to inject malicious SQL code. Exploitation can lead to unauthorized access to sensitive database information. The vulnerability impacts versions up to and including 1.6.9.27, and a patch is available in version 1.6.9.29.
The SQL Injection vulnerability in Simply Schedule Appointments allows an unauthenticated attacker to manipulate database queries. Successful exploitation could enable attackers to extract sensitive data such as user credentials (usernames, passwords, email addresses), appointment details, and potentially other stored information. The attacker could also modify data, leading to data corruption or denial of service. While direct remote code execution is unlikely, the ability to extract database credentials could facilitate lateral movement within the WordPress environment, potentially compromising other plugins or the core WordPress installation itself. The blast radius extends to any data stored within the plugin's database, making it a significant risk for organizations relying on this plugin for appointment scheduling.
CVE-2026-39493 was published on 2026-04-08. Severity is rated as High (CVSS 7.5). Currently, there are no publicly known Proof-of-Concept (POC) exploits. The vulnerability is not listed on KEV or EPSS, indicating a low to medium probability of active exploitation at this time. Monitor WordPress security forums and vulnerability databases for updates.

CVSS 向量
The primary mitigation for CVE-2026-39493 is to immediately upgrade the Appointment Booking Calendar — Simply Schedule Appointments Booking Plugin to version 1.6.9.29 or later. If upgrading is not immediately feasible due to compatibility issues or testing requirements, consider implementing a Web Application Firewall (WAF) rule to filter potentially malicious SQL injection attempts targeting the vulnerable parameter.
