AI Analysis
Technical Summary
CVE-2026-18666 is a SQL injection vulnerability (CWE-89) in the Library Management System WordPress plugin prior to version 3.6.7. The plugin fails to sanitize and escape user-supplied input before incorporating it into SQL queries, allowing users with as low a privilege as Subscriber to perform SQL injection attacks. This can result in unauthorized extraction of arbitrary data from the database, including sensitive information such as user password hashes. The vulnerability is publicly known but no vendor advisory or patch has been published yet.
Potential Impact
An attacker with Subscriber-level access can exploit this vulnerability to perform SQL injection attacks, potentially extracting sensitive data from the database, including user password hashes. This compromises data confidentiality but does not directly affect availability or integrity according to the CVSS vector. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Subscriber role capabilities if possible and monitor for suspicious activity related to SQL injection attempts.
