CVE-2026-13191: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in mischiefmarmot Create
The Create plugin for WordPress is vulnerable to generic SQL Injection via the 'order_by' parameter in all versions up to, and including, 2.5.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with author-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The REST endpoint permission callback defaults to the publish_posts capability, meaning any Author-level user or above can reach the vulnerable code path without any additional preconditions.
AI Analysis
Technical Summary
CVE-2026-13191 describes a SQL Injection vulnerability (CWE-89) in the Create WordPress plugin affecting all versions up to and including 2.5.3. The flaw exists because the 'order_by' parameter is not properly escaped and the SQL query is not sufficiently prepared, allowing authenticated users with author-level access or higher to inject additional SQL commands. The REST endpoint permission callback defaults to the publish_posts capability, enabling exploitation by any user with author-level permissions or above without further restrictions.
Potential Impact
An attacker with author-level access or higher can exploit this vulnerability to execute arbitrary SQL queries appended to existing queries. This can lead to unauthorized extraction of sensitive information from the database. The vulnerability does not affect confidentiality, integrity, or availability beyond the described data exposure, and does not require higher privileges than author-level.
Mitigation Recommendations
No official patch or fix is currently documented. Users should monitor the vendor advisory for updates. Until a fix is available, restrict author-level access to trusted users only and consider disabling or limiting use of the vulnerable REST endpoint if possible.
