CVE-2026-1581
Published: 19 February 2026
Summary
CVE-2026-1581 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 in the top 6.9% of CVEs by exploit likelihood; 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
The wpForo Forum plugin for WordPress is vulnerable to time-based SQL Injection via the 'wpfob' parameter in all versions up to and including 2.4.14. The flaw stems from insufficient escaping of user-supplied input and the absence of prepared statements on an existing SQL query, allowing an attacker to alter query logic. The issue carries a CVSS 3.1 score of 7.5 with network attack vector and no required authentication or user interaction.
Unauthenticated attackers can supply a crafted 'wpfob' value to append additional SQL statements to existing queries, enabling extraction of sensitive database contents such as user credentials or forum data. Exploitation requires only a standard HTTP request to an affected WordPress site running the plugin.
Public references, including Wordfence advisory data and WordPress plugin repository changesets, indicate that the vulnerability was addressed through code updates that improve input sanitization and query parameterization; site administrators should apply the available plugin patch or upgrade beyond version 2.4.14.
The associated EPSS score rose from a low baseline to a peak of 0.1772 on 2026-04-02 before receding to the current value of 0.0972, signaling increased exploitation interest after public disclosure.
