Official Description

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 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Risk Analysis

This high-severity vulnerability in the wpForo Forum plugin for WordPress allows unauthenticated attackers to perform time-based SQL Injection. This can lead to the extraction of sensitive information from the database. The high CVSS score of 7.5 and confirmed exploitation by CISA (is_in_kev: true) indicate a significant risk to data confidentiality.

Active exploitation of this vulnerability has been observed in the wild. The CVSS vector (AV:N/AC:L) indicates that this flaw is remotely exploitable with low attack complexity.

Recommended Action

Update the wpForo Forum plugin to the latest secure version, beyond 2.4.14, to address this SQL injection vulnerability. Implement robust input validation and parameterized queries in web applications to prevent similar flaws.

Technical Analysis

CVE-2026-1581 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 7.5.

CISA has added CVE-2026-1581 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.

From a weakness classification perspective (CWE-89): SQL injection vulnerabilities allow attackers to manipulate database queries, potentially exposing or modifying sensitive data.
