FKIE_CVE-2023-5527

Vulnerability from fkie_nvd - Published: 2024-06-18 06:15 - Updated: 2026-06-17 06:48
Severity
7.4 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L
8.0 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H
Summary
The Business Directory Plugin plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 6.4.3 via the class-csv-exporter.php file. This allows authenticated attackers, with author-level permissions and above, to embed untrusted input into CSV files exported by administrators, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.
