CVE-2026-15802 in Foodbakery Plugin
Summary
by MITRE • 07/22/2026
The WP Foodbakery plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'delete_locations_backup_file_callback' function in all versions up to, and including, 4.9. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

Analysis

The WP Foodbakery plugin presents a critical security vulnerability that stems from inadequate input validation within its file handling mechanisms. This weakness exists in the 'delete_locations_backup_file_callback' function, which processes file deletion requests without properly sanitizing or validating the file paths provided by users. The vulnerability affects all versions up to and including 4.9, creating a persistent risk for WordPress installations that utilize this plugin. The flaw represents a classic path traversal vulnerability where attacker-controlled input directly influences the file system operations, bypassing normal security boundaries that should protect against unauthorized file access.
Authentication requirements for exploitation are relatively low, as attackers need only subscriber-level privileges or higher to leverage this vulnerability effectively. This access level is often achievable through social engineering, compromised credentials, or other initial compromise techniques commonly used in web application attacks. The vulnerability's impact extends beyond simple file deletion, as it can be weaponized to target critical system files such as wp-config.php, which contains database credentials and cryptographic keys essential for WordPress operation. When such files are removed or corrupted, the consequences can range from complete application compromise to full system takeover, making this vulnerability particularly dangerous in production environments.
The operational implications of this vulnerability align with several ATT&CK framework techniques including privilege escalation through malicious file deletion and persistence mechanisms. Attackers can use this weakness as a stepping stone for more extensive compromises by deleting backup files that could aid in system recovery or removing configuration files that would cause application instability. The vulnerability also intersects with CWE-22, which defines path traversal flaws as weaknesses that allow attackers to access files outside the intended directory structure. Organizations running vulnerable versions of WP Foodbakery face significant risk of data loss, service disruption, and potential complete system compromise when this vulnerability is exploited.
Mitigation strategies should focus on immediate plugin updates to versions that address the validation issue, followed by comprehensive security audits of affected systems. Network segmentation and access control measures can help limit the impact if exploitation occurs, while regular monitoring of file system changes can provide early detection of malicious activity. Security teams should also implement proper input validation controls at multiple layers including application firewalls, web application security solutions, and database-level restrictions to prevent similar vulnerabilities from being exploited in other components of the system architecture.
