CVE-2025-13133: CWE-1236 Improper Neutralization of Formula Elements in a CSV File in vaniivan Simple User Import Export
The Simple User Import Export plugin for WordPress is vulnerable to CSV Injection in all versions up to, and including, 1.1.7 via the 'Import/export users' function. This makes it possible for authenticated attackers, with Administrator-level access and above, 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
CVE-2025-13133 is a CSV Injection vulnerability in the Simple User Import Export WordPress plugin by vaniivan. The flaw exists in all versions up to 1.1.7 and allows authenticated administrators to embed untrusted input into CSV exports. This improper neutralization of formula elements (CWE-1236) can lead to code execution when the CSV file is opened in spreadsheet software that evaluates formulas. The CVSS 3.1 base score is 6.6, reflecting network attack vector, low attack complexity, high privileges required, no user interaction, and impacts on confidentiality, integrity, and availability.
Potential Impact
An attacker with Administrator-level access can craft malicious CSV files that execute code when opened by a user in a vulnerable spreadsheet application. This can lead to partial compromise of confidentiality, integrity, and availability of the affected system or data. The vulnerability requires high privileges to exploit and no known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Administrator-level access to trusted users only and exercise caution when exporting and opening CSV files from this plugin. Avoid opening exported CSV files in spreadsheet software that automatically executes formulas or disable formula evaluation features if possible.
