CVE-2026-2599: CWE-502 Deserialization of Untrusted Data in crmperks Database for Contact Form 7, WPforms, Elementor forms
The Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.4.7 via deserialization of untrusted input in the 'download_csv' function. This makes it possible for unauthenticated attackers to inject a PHP Object. 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.
AI Analysis
Technical Summary
CVE-2026-2599 is a critical PHP Object Injection vulnerability (CWE-502) in the crmperks Database plugin for Contact Form 7, WPforms, and Elementor forms for WordPress. The flaw exists in the 'download_csv' function where untrusted input is deserialized, enabling unauthenticated attackers to inject PHP objects. Exploitation depends on the presence of a POP chain gadget in other installed plugins or themes, which could enable file deletion, data disclosure, or code execution. No patch or official fix information is provided in the available data.
Potential Impact
If exploited in an environment where a POP chain gadget is present, this vulnerability can lead to high-impact consequences including arbitrary code execution, deletion of files, and exposure of sensitive data. Without a POP chain, the vulnerability cannot be leveraged to cause harm. The CVSS 3.1 score is 9.8 (critical), reflecting the potential severity if the prerequisite conditions are met.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, administrators should review installed plugins and themes for potential POP chain gadgets that could be exploited in conjunction with this vulnerability. Consider disabling or removing the crmperks Database plugin if not essential, or restricting access to the vulnerable functionality to trusted users only. Monitor vendor channels for updates and patches.
