CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2026-3584 is a critical-severity Code Injection (CWE-94) vulnerability in Wordpress (inferred from references). Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The Kali Forms plugin for WordPress is vulnerable to remote code execution in all versions through 2.4.9. The flaw resides in the form_process function, where prepare_post_data maps attacker-controlled keys directly into internal placeholder storage that is later passed to call_user_func, enabling arbitrary PHP execution. The issue is tracked as CVE-2026-3584 with a CVSS 3.1 score of 9.8 and is associated with CWE-94.
Unauthenticated attackers can exploit the vulnerability over the network by submitting specially crafted form data that populates the placeholders with callable values. Successful exploitation grants the attacker the ability to run arbitrary code on the server, resulting in full compromise of confidentiality, integrity, and availability.
Public references include the vulnerable code path in the plugin repository, a WordPress Trac changeset that addresses the issue, and a detailed entry from Wordfence threat intelligence, indicating that administrators should apply the available update to resolve the exposure. The EPSS score has reached a peak of 0.3386 with a current value of 0.2873.

Vulnerability Data
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.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation finds code paths that accept and execute externally influenced strings.
Input validation directly stops untrusted data from being used to construct executable code without neutralization.
Least privilege limits the damage an injected code fragment can perform once executed.
Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.
Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
