CVE-2026-5100 is an SQL Injection vulnerability in the AWP Classifieds plugin for WordPress, affecting versions up to and including 4.4.5. The issue arises from improper neutralization of special elements in the 'regions' parameter array keys, allowing unauthenticated attackers to append malicious SQL queries. This is due to insufficient escaping of user input and lack of prepared statements in the affected SQL queries. The vulnerability can be exploited remotely without authentication to extract sensitive data from the backend database. The CVSS 3.1 base score is 7.5, reflecting high impact on confidentiality with no impact on integrity or availability.

Successful exploitation allows unauthenticated attackers to extract sensitive information from the database by injecting SQL commands through the vulnerable 'regions' parameter. This compromises data confidentiality but does not affect data integrity or availability. There are no known active exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling or restricting access to the vulnerable plugin or applying custom input validation and escaping as a temporary mitigation. Monitor vendor channels for updates and apply official patches promptly once available.
