CVE-2025-2485: CWE-502 Deserialization of Untrusted Data in glenwpcoder Drag and Drop Multiple File Upload for Contact Form 7
The Drag and Drop Multiple File Upload for Contact Form 7 plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.3.8.7 via deserialization of untrusted input from the 'dnd_upload_cf7_upload' function. This makes it possible for attackers to inject a PHP Object through a PHAR file. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. This vulnerability may be exploited by unauthenticated attackers when a form is present on the site with the file upload action. The Flamingo plugin must be installed and activated in order to exploit the vulnerability. The vulnerability was partially patched in version 1.3.8.8.
AI Analysis
Technical Summary
CVE-2025-2485 is a deserialization of untrusted data vulnerability (CWE-502) in the Drag and Drop Multiple File Upload for Contact Form 7 WordPress plugin. It allows unauthenticated attackers to inject PHP objects via a PHAR file through the 'dnd_upload_cf7_upload' function. Exploitation depends on the presence of a PHP Object Injection POP chain in other installed plugins or themes, which could lead to high-impact actions such as arbitrary file deletion, sensitive data disclosure, or remote code execution. The Flamingo plugin must be active for exploitation. The vulnerability was partially addressed in version 1.3.8.8, but no full patch status is confirmed.
Potential Impact
If exploited in an environment where a PHP Object Injection POP chain exists in other plugins or themes, attackers could achieve high-impact outcomes including arbitrary file deletion, sensitive data exposure, or remote code execution. Without such a POP chain, this vulnerability has no direct impact. Exploitation requires unauthenticated access to a form with file upload functionality and the Flamingo plugin installed and activated.
Mitigation Recommendations
A partial patch was introduced in version 1.3.8.8 of the plugin. Patch status is not yet confirmed as fully resolved—check the vendor advisory for current remediation guidance. Until a full fix is confirmed, administrators should consider disabling the vulnerable plugin or the file upload feature, and ensure the Flamingo plugin is not active if not required. Review installed plugins and themes for potential POP chains that could be leveraged in conjunction with this vulnerability.
