CVE-2025-26933 is a Local File Inclusion (LFI) vulnerability found in the WC Place Order Without Payment WordPress plugin developed by Nitin Prakash, affecting all versions up to and including 2.6.7. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements. This flaw allows an attacker to manipulate the filename input, causing the application to include unintended local files from the server filesystem. Such inclusion can lead to disclosure of sensitive information such as configuration files, source code, or credentials, and in some cases, may enable remote code execution if the attacker can upload malicious files or leverage other vulnerabilities. The vulnerability is classified as a PHP Remote File Inclusion type but currently only confirmed as Local File Inclusion. No public exploits are known at this time, but the vulnerability is published and should be considered exploitable due to the nature of PHP file inclusion flaws. The plugin is used in WordPress environments to facilitate order placement without payment, which is a niche but critical function in some e-commerce workflows. The lack of a CVSS score indicates this is a newly disclosed vulnerability, with severity assessment based on technical impact and exploitability. The vulnerability requires no authentication or user interaction, increasing its risk profile. No official patches or updates are linked yet, so users must monitor vendor advisories. The vulnerability was reserved in February 2025 and published in March 2025, indicating recent discovery and disclosure.

The impact of CVE-2025-26933 is significant for organizations using the affected WC Place Order Without Payment plugin in their WordPress e-commerce platforms. Successful exploitation can lead to unauthorized disclosure of sensitive server files, including credentials, configuration files, and source code, compromising confidentiality. Attackers may also execute arbitrary code if combined with other vulnerabilities or file upload capabilities, threatening system integrity and availability. This can result in website defacement, data breaches, or full server compromise. The vulnerability can disrupt business operations, damage reputation, and lead to regulatory non-compliance if customer data is exposed. Since the plugin facilitates order placement without payment, attackers might also manipulate order workflows, causing financial or operational fraud. The lack of authentication requirement and ease of exploitation increase the likelihood of attacks, especially in automated scanning and exploitation campaigns targeting vulnerable WordPress plugins. Organizations worldwide relying on this plugin or similar PHP-based e-commerce extensions are at risk, particularly those with limited security monitoring or patch management processes.

To mitigate CVE-2025-26933, organizations should immediately identify if they use the WC Place Order Without Payment plugin version 2.6.7 or earlier. If so, they should monitor the vendor's official channels for patches or updates addressing this vulnerability and apply them promptly once available. In the absence of an official patch, administrators should consider temporarily disabling or removing the plugin to eliminate exposure. Implement strict input validation and sanitization on any user-controlled parameters that influence file inclusion paths, ensuring only allowed filenames or directories are processed. Employ web application firewalls (WAFs) with rules designed to detect and block suspicious file inclusion attempts. Restrict PHP include paths and disable allow_url_include and allow_url_fopen directives in PHP configurations to reduce risk. Conduct thorough security audits and scanning for signs of exploitation or compromise. Regularly back up website data and configurations to enable recovery if an incident occurs. Educate development teams on secure coding practices to prevent similar vulnerabilities in custom plugins or themes.
