CVE-2026-5100
Published: 05 May 2026
Summary
CVE-2026-5100 is a high-severity SQL Injection (CWE-89) vulnerability in Wordpress (inferred from references). Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 38.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2026-5100 is a SQL injection vulnerability in the AWP Classifieds plugin for WordPress, affecting versions up to and including 4.4.5. The flaw arises from insufficient escaping of the user-supplied 'regions' parameter array keys and inadequate preparation of the existing SQL query, allowing attackers to append malicious SQL queries. This issue, classified under CWE-89, carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), highlighting high confidentiality impact with no requirements for privileges or user interaction.
Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity. By manipulating the 'regions' parameter in plugin requests, they can inject additional SQL queries into existing ones, enabling extraction of sensitive information from the database, such as user credentials or other confidential data.
The provided references point to specific locations in the plugin's source code, including lines 168, 174, 63, and 70 in frontend/page-search-ads.php, and line 1240 in functions.php, where the insufficient escaping and query preparation occur. No explicit patch or advisory details are available in the given information, but security practitioners should review these code sections and update to a fixed version if released.

Why these techniques?
SQL injection in unauthenticated public-facing WordPress plugin directly enables remote exploitation of web applications (T1190) and permits arbitrary database queries for extraction of sensitive data such as credentials (T1213.006).

SI-10 directly prevents SQL injection by requiring validation and sanitization of user-supplied inputs like the unescaped 'regions' parameter array keys.
SI-2 requires identifying, reporting, and correcting specific flaws such as the insufficient escaping and query preparation in the AWP Classifieds plugin's frontend/page-search-ads.php and functions.php.
RA-5 mandates vulnerability scanning that would identify the SQL injection flaw in the plugin, enabling remediation before exploitation.
