CVE intelligence and bounded remediation

CVE-2025-4203 — wpForo Forum security vulnerability

High CVSS 7.5

The 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.

Matched remediation archetype

SQL and data-query injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace request, message, file, and stored values into SQL, ORM query fragments, filters, sort expressions, and other data-query languages.
  • Inventory database roles, reachable schemas, multi-tenant boundaries, and whether stacked or administrative operations are enabled.
  • Check both direct queries and second-order use of previously stored values.

Remediate safely

  • Use parameterized queries or safe query builders for all values; map identifiers and operators through explicit allowlists.
  • Remove raw query concatenation and give the application account only the tables and operations it requires.
  • Update affected data-access components and add regression tests for query structure preservation with inert edge-case inputs.
