CVE-2025-4203
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe wpForo Forum plugin for WordPress is vulnerable to error‐based or time-based SQL Injection via the get_members() function in all versions up to, and including, 2.4.8 due to missing integer validation on the 'offset' and 'row_count' parameters. The function blindly interpolates 'row_count' into a 'LIMIT offset,row_count' clause using esc_sql() rather than enforcing numeric values. MySQL 5.x’s grammar allows a 'PROCEDURE ANALYSE' clause immediately after a LIMIT clause. Unauthenticated attackers controlling 'row_count' can append a stored‐procedure call, enabling error‐based or time‐based blind SQL injection that can be used to extract sensitive information from the database.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe wpForo Forum plugin for WordPress versions up to 2.4.8 contains an unauthenticated SQL injection in the get_members() function. The 'row_count' parameter is passed through esc_sql() and directly interpolated into a LIMIT clause without integer type validation. Since MySQL 5.x permits PROCEDURE ANALYSE after LIMIT, attackers can append stored-procedure calls to achieve error-based or time-based blind SQL injection.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify wpForo plugin installation and versionNavigate to WordPress admin > Plugins and check the installed version of wpForo Forum plugin, or inspect the main plugin file (typically wp-content/plugins/wpforo/wpforo.php) for the version definition.Affected if The installed version is 2.4.8 or lower.
-
Confirm the vulnerable get_members() function existsInspect the wpForo plugin files for the get_members() function definition, typically found in plugin core files under the wpforo directory.Affected if The function exists in the installed version and processes the 'row_count' parameter.
-
Check if members endpoint is publicly accessibleAttempt to access the wpForo members page (typically /community/members/ or similar URL path depending on wpForo configuration) without authentication.Affected if The members listing is accessible without requiring login (unauthenticated).
-
Verify row_count parameter handlingReview the get_members() function code to confirm the 'row_count' parameter is passed through esc_sql() but lacks integer type casting or validation before being used in the LIMIT clause.Affected if The parameter is not validated as an integer before SQL interpolation.
If wpForo Forum plugin version is 2.4.8 or lower AND the members functionality is publicly accessible without authentication, the environment is affected by this SQL injection vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate wpForo Forum plugin to version 2.4.9 or later. If immediate update is not possible, consider disabling the plugin or implementing WAF rules to block SQL injection attempts on the affected parameters.
wpForo Forum version 2.4.9 or later
- Log in to WordPress admin dashboard
- Navigate to Plugins > Installed Plugins
- Locate wpForo Forum plugin
- Check if current version is 2.4.8 or earlier
- If vulnerable, click 'Update Now' to upgrade to latest version
- Alternatively, download wpForo Forum 2.4.9 or later from wordpress.org/plugins/wpforo-forum/ and upload via Plugins > Add New > Upload Plugin
- After update, verify version number reflects 2.4.9 or higher
