Published: 18 February 2026
Summary
CVE-2026-2576 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 12.4th 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-2026-2576 is a time-based SQL injection vulnerability in the Business Directory Plugin – Easy Listing Directories for WordPress, affecting all versions up to and including 6.4.2. The flaw arises from insufficient escaping of the user-supplied 'payment' parameter and lack of proper preparation in the existing SQL query, allowing attackers to append malicious SQL queries. This issue is classified under CWE-89 with 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), indicating high confidentiality impact without requiring authentication or user interaction.
Unauthenticated attackers can exploit this vulnerability remotely by sending crafted requests to the affected 'payment' parameter, enabling time-based blind SQL injection techniques to extract sensitive information from the database, such as user credentials or other confidential data hosted by WordPress sites using the plugin.
References, including Wordfence's threat intelligence advisory and WordPress plugin trac browser links, highlight the vulnerable code in files like includes/controllers/pages/class-checkout.php (line 126) and includes/db/class-db-query-set.php (line 37). Mitigation involves updating to a patched version, as evidenced by changeset 3463307 which addresses the issue in the trunk of the business-directory-plugin repository.
