CVE-2026-12081: CWE-502 Deserialization of Untrusted Data in Database for Contact Form 7, WPforms, Elementor forms
The Database for Contact Form 7, WPforms, Elementor forms WordPress plugin before 1.5.2 does not restrict the PHP classes allowed when unserializing an attacker-supplied form-field value, allowing unauthenticated users to inject arbitrary PHP objects that are instantiated when an administrator views the stored entry. This is an incomplete fix of CVE-2025-7384 and CVE-2026-2599, whose deserialization paths were hardened while the entry-editor file-field path was missed.
AI Analysis
Technical Summary
The vulnerability exists because the plugin does not restrict which PHP classes can be unserialized from attacker-supplied form-field data. This enables unauthenticated attackers to inject arbitrary PHP objects that get instantiated when an administrator views the stored form entry. It is an incomplete fix of earlier deserialization vulnerabilities (CVE-2025-7384 and CVE-2026-2599), where the entry-editor file-field path was overlooked. No CVSS score or patch information is currently available, and no known exploits have been reported in the wild.
Potential Impact
Successful exploitation could allow unauthenticated attackers to execute arbitrary PHP code in the context of the WordPress site when an administrator views the maliciously crafted form entry. This could lead to full site compromise or data breach depending on the privileges of the WordPress process. However, no known exploits are reported yet.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, administrators should exercise caution when viewing form entries and consider restricting access to the entry editor. Monitor vendor channels for updates addressing this incomplete fix.
