CVE-2024-7620: Fastlinemedia Customizer Export/import

Medium severity, CVSS 6.6. EPSS: 0.7% chance of exploitation in the next 30 days.

The Customizer Export/Import plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the '_import' function in all versions up to, and including, 0.9.7. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. NOTE: This vulnerability is only exploitable when used in conjunction with a race condition as the uploaded file is deleted shortly after it is created.

Affected products

• Fastlinemedia Customizer Export/import: before 0.9.7.1 (fixed in 0.9.7.1)
