CVE-2025-2267 in WP01 Plugin
Summary
by MITRE • 03/15/2025
The WP01 plugin for WordPress is vulnerable to Arbitrary File Download in all versions up to, and including, 2.6.2 due to a missing capability check and insufficient restrictions on the make_archive() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to download and read the contents of arbitrary files on the server, which can contain sensitive information.

The WP01 plugin for WordPress presents a critical security vulnerability classified as CVE-2025-2267 that affects all versions up to and including 2.6.2. This vulnerability stems from a fundamental flaw in the plugin's access control mechanisms and file handling procedures, creating a pathway for unauthorized data extraction. The issue specifically targets the make_archive() function which lacks proper validation and capability checks, allowing malicious actors with minimal privileges to exploit this weakness. The vulnerability operates under the broader category of insecure file handling practices that have been consistently identified as high-risk in cybersecurity frameworks and industry standards.
The technical implementation of this flaw resides in the make_archive() function's failure to properly validate user inputs and verify authorization levels before processing file download requests. Authentication checks are completely bypassed, enabling any user with Subscriber-level access or higher to initiate arbitrary file download operations. This represents a classic case of privilege escalation through inadequate access controls, where the system fails to enforce proper capability checks that should prevent unauthorized file system access. The vulnerability manifests as a direct consequence of insufficient input validation and improper access control enforcement, creating a pathway for information disclosure attacks.
Operational impact of this vulnerability extends beyond simple information disclosure, as it allows attackers to access potentially sensitive server files including configuration files, database credentials, application code, and other system artifacts that could facilitate further attacks. The compromised system becomes vulnerable to advanced persistent threats where attackers can gather intelligence about the server environment, application architecture, and potential weaknesses in the broader infrastructure. This vulnerability directly impacts the confidentiality and integrity of the WordPress installation, potentially exposing the entire platform to more sophisticated attack vectors. The security implications align with attack patterns documented in the MITRE ATT&CK framework under the information gathering and credential access domains, where attackers seek to enumerate system information and extract sensitive data.
Mitigation strategies for this vulnerability require immediate patching of the WP01 plugin to version 2.6.3 or later, which includes proper capability checks and input validation for the make_archive() function. Organizations should also implement additional security measures such as restricting file permissions, monitoring for unusual download patterns, and conducting regular security audits of installed plugins. The fix addresses the core issue by implementing proper capability verification before file operations and by adding input sanitization to prevent malicious file path traversal attempts. Security teams should also consider implementing web application firewalls to detect and block suspicious download requests, and conduct comprehensive vulnerability assessments to identify other potential weaknesses in the WordPress ecosystem. This vulnerability exemplifies the importance of proper access control implementation and input validation as outlined in CWE categories related to privilege escalation and information exposure.
