What is CVE-2026-0829?

The Frontend File Manager Plugin for WordPress, up to version 23.5, presents a significant security risk by permitting unauthenticated users to send emails from the site, bypassing necessary security protocols. This loophole allows malicious actors to exploit the WordPress site as a relay for spam or phishing emails, consequently endangering the site's reputation and integrity. Moreover, the vulnerability enables attackers to guess file IDs, granting them unauthorized access to shared files and potentially sensitive information, thereby posing a substantial risk to user data privacy.
