CVE-2024-3214: CWE-1236 Improper Neutralization of Formula Elements in a CSV File in Relevanssi Relevanssi Premium
The Relevanssi – A Better Search plugin for WordPress is vulnerable to CSV Injection in all versions up to, and including, 4.22.1. This makes it possible for unauthenticated attackers to embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.
AI Analysis
Technical Summary
The Relevanssi Premium WordPress plugin versions up to 4.22.1 suffer from an improper neutralization of formula elements in CSV files (CWE-1236), enabling CSV Injection. This vulnerability permits unauthenticated attackers to embed malicious input into CSV exports. If a user opens the exported CSV file in spreadsheet software that evaluates formulas, this can lead to unintended code execution or command injection on the local system. The CVSS 3.1 base score is 5.8, reflecting network attack vector, no privileges required, no user interaction, and impact limited to integrity.
Potential Impact
An attacker can inject malicious formulas into CSV exports generated by the plugin. When these files are opened in vulnerable spreadsheet applications, it may result in execution of arbitrary commands or code on the local machine. The impact affects data integrity but does not directly compromise confidentiality or availability. No evidence of active exploitation is currently known.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should avoid opening CSV files exported from affected versions in spreadsheet software that automatically evaluates formulas. Consider sanitizing or validating CSV content before export to neutralize formula elements.
