Key points
- CVE-2026-112327 is a critical SQL injection vulnerability in TMS Amelia.
- The flaw affects all versions of the plugin up to and including 2.4.11.
- The NVD record does not state whether a patch has been released.
Security operations teams must prioritize the assessment of WordPress installations running the TMS Amelia booking plugin. The National Vulnerability Database records CVE-2026-112327 as a critical severity issue with a CVSS score of 9.3. This vulnerability involves improper neutralization of special elements in SQL commands, commonly known as SQL injection. The flaw is present in TMS Amelia versions ranging from the earliest available version through 2.4.11. As Vuln Post reported on 2026-10-15, similar SQL injection flaws have recently impacted other event calendar plugins, highlighting the persistent risk in this software category.
In plain English
SQL injection occurs when an application fails to properly filter user input before passing it to a database. In this case, the TMS Amelia plugin does not correctly neutralize special characters in SQL commands. An attacker could potentially craft malicious input that the database interprets as executable code rather than data. This allows the attacker to interfere with the queries the application makes to its database. The vulnerability is classified under CWE-89, which covers improper neutralization of special elements in SQL commands.
The background
The TMS Amelia plugin is a popular booking solution for WordPress sites. The NVD record specifies that the issue affects the ameliabooking component. The vulnerability allows for SQL injection, which can lead to unauthorized access to or modification of data stored in the database. The affected version range is broad, covering all releases up to 2.4.11. The source material does not provide information on the availability of a fix. This mirrors the situation with the CP Multi View Event Calendar plugin, where a high-severity SQL injection flaw also lacked a confirmed patch status.
What changes now
Sites running TMS Amelia up to 2.4.11 are currently exposed to this critical vulnerability. The NVD record lists the vulnerability but does not confirm a patch status. Administrators should verify their installed version against the affected range. If the plugin is not actively used, disabling it may be a temporary measure. Monitoring for unauthorized database activity is essential. Teams should also review access controls to limit who can interact with the booking forms. As Vuln Post noted on 2026-10-16, similar critical blind SQL injection flaws in other plugins have required immediate updates to mitigate risk.
Who needs to act first
Teams should prioritize sites that expose the TMS Amelia booking forms to the public internet. Exposed systems require immediate attention to limit potential data exposure. Implement strict input validation at the web application firewall level to block common SQL injection patterns. Ensure that database credentials used by the plugin have the minimum necessary privileges, restricting write access where possible. Back up all site data and database configurations before making any changes to the environment. Monitor logs for unusual query patterns or unauthorized access attempts, which could indicate exploitation.
Background: Input validation
Input validation cyber security requires checking every piece of data entering a system for type, length, and format. You must reject unexpected data immediately. This prevents attackers from injecting malicious code or causing system crashes. Trusting user input without strict rules allows breaches to occur.

What to do and how to stay safe: TMS Amelia
- Verify the installed version of TMS Amelia and confirm if it is 2.4.11 or earlier.
- Restrict public access to booking forms if possible until a patch is available.
- Implement web application firewall rules to detect and block SQL injection attempts.
- Monitor database logs for anomalous queries or unauthorized access patterns.
