CVE-2026-71287
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk23th percentile - higher than 23% of all known CVEs
Summary
Cacti's sanitize_sql_column sanitizes user-supplied ORDER BY column names using a regex that retains letters, digits, underscore, parentheses, and dot. This allows certain payloads to pass through completely unmodified.
Risk Assessment
An attacker could exploit this to inject SQL, potentially leading to unauthorized data access or database integrity compromise.
Recommendation
Update Cacti to a patched version or tighten input validation to disallow dangerous patterns.

Original NVD description (English source)
Cacti's sanitize_sql_column (lib/functions.php) sanitizes user-supplied ORDER BY column names using the regex . Because this allowlist retains letters, digits, underscore, parentheses, and dot (intended to support expressions like COUNT(id) and table.column), a payload such as passes through completely unmodified.
