CVE-2025-8289 - Redirection For Contact Form 7 Plugin

CVE-2025-8289

The Redirection for Contact Form 7 plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.2.4 via deserialization of untrusted input in the delete_associated_files function. This makes it possible for unauthenticated attackers to inject a PHP Object. This vulnerability may be exploited by unauthenticated attackers when a form is present on the site with a file upload action, and doesn't affect sites with PHP version > 8. This vulnerability also requires the 'Redirection For Contact Form 7 Extension - Create Post' extension to be installed and activated in order to be exploited. 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. We confirmed there is a usable gadget in Contact Form 7 plugin that makes arbitrary file deletion possible when installed with this plugin. Given Contact Form 7 is a requirement of this plugin, it is likely that any site with this plugin and the 'Redirection For Contact Form 7 Extension - Create Post' extension enabled is vulnerable to arbitrary file deletion.

Potential Impact

Severity is HIGH (CVSS 7.5). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as High based on remote code execution potential, low-bar exploit prerequisites.

Primary risk drivers: remote code execution potential, low-bar exploit prerequisites

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
