CVE-2026-3584
CWE-94Published: March 20, 2026· Updated: Mar 23, 2026
Official Description
The Kali Forms plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.4.9 via the 'form_process' function. This is due to the 'prepare_post_data' function mapping user-supplied keys directly into internal placeholder storage, combined with the use of 'call_user_func' on these placeholder values. This makes it possible for unauthenticated attackers to execute code on the server.
Technical Analysis
CVE-2026-3584 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
CISA has added CVE-2026-3584 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
