Database for Contact Form 7, WPforms, Elementor forms <= 1.4.3 - Unauthenticated PHP Object Injection to Arbitrary File Deletion
Noroxi assessment
Priority: Monitor (action score 39/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 1.3% (FIRST EPSS); higher than 70.2% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- No fixed version is recorded, but the references include a patch (commit or PR) link.
- Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. See the fix and affected versions sections below.

Primary sources: NVD · CVE.org · FIRST EPSS
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, 1.4.3 via deserialization of untrusted input in the get_lead_detail function. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain in the Contact Form 7 plugin, which is likely to be used alongside, allows attackers to delete arbitrary files, leading to a denial of service or remote code execution when the wp-config.php file is deleted.
