Attackers have been actively exploiting CVE-2026-3300, a critical remote code execution flaw in the Everest Forms Pro WordPress plugin, to compromise vulnerable websites. The bug affects all versions through 1.9.12 and originates in the plugin’s Calculation add-on, where attacker-controlled input is passed into PHP’s eval() function without proper escaping of single quotes, allowing unauthenticated attackers to execute arbitrary PHP code on target sites.
Security researchers reported that exploitation has enabled full site takeover, including the creation of rogue administrator accounts and deployment of webshells. Wordfence said it observed attacks beginning on April 13 and blocked more than 29,300 exploit attempts, with a notable spike in activity on May 16. Reported indicators of compromise include an administrator account named "diksimarina", the email diksimarina@gmail.com, and requests originating from 202.56.2.126. The vendor, WPEverest, addressed the issue in version 1.9.13, and site administrators were urged to update immediately.

Attackers are actively exploiting **CVE-2026-3300**, a critical unauthenticated remote code execution flaw in the **Everest Forms Pro** WordPress plugin, to fully compromise vulnerable sites. The bug affects versions through **1.9.12** and was fixed in **1.9.13**. It stems from the plugin’s Complex Calculation feature, where user-controlled input in `process_filter()` is concatenated into PHP code and executed with `eval()`, allowing arbitrary PHP injection through crafted form submissions, often via the `/wp-admin/admin-ajax.php` endpoint. Wordfence reported exploitation beginning on April 13 and escalating into mass attacks, with more than **29,300** exploit attempts blocked overall and over **17,900** on May 16 alone. A recurring payload creates a rogue administrator account named **`diksimarina`**, giving attackers persistent access to upload webshells, install backdoors, alter site content, and potentially pivot deeper into the hosting environment. Defenders are being urged to upgrade immediately to **1.9.13 or later**, audit WordPress administrator accounts for unauthorized users, and review logs for suspicious requests and known malicious IP activity.

Two high-severity vulnerabilities have been disclosed in widely deployed WordPress plugins, exposing internet-facing sites to **unauthenticated compromise**. `CVE-2026-3584` affects **Kali Forms** through version `2.4.9` and allows **remote code execution** because user-controlled input can be mapped into internal placeholder storage and later invoked via `call_user_func` in the `form_process` path. The issue is classified as `CWE-94` and carries a `CVSS 3.1` score with the vector `AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`, indicating critical impact on confidentiality, integrity, and availability. A second flaw, `CVE-2026-4038`, affects **Aimogen Pro** through version `2.7.5` and enables **unauthenticated privilege escalation** through an arbitrary function call in `aiomatic_call_ai_function_realtime` caused by a missing capability check. According to the disclosure, attackers can invoke WordPress functions such as `update_option` to change the default registration role to administrator and enable user registration, effectively creating a path to full site takeover. The vulnerability is tracked as `CWE-862` and was likewise rated with a high-impact `CVSS 3.1` vector of `AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`.

Attackers are actively exploiting `CVE-2026-14894`, a critical CVSS 9.8 unauthenticated arbitrary-file-upload vulnerability in the WordPress **Super Forms – Drag & Drop Form Builder** plugin through version `6.3.313`. Insufficient file-type validation and a weak nonce mechanism in unauthenticated AJAX handlers let attackers obtain a valid nonce, upload executable PHP files, and potentially gain remote code execution and full control of affected sites. Roughly 13,000 active installations may be exposed. Exploitation was observed beginning July 14 and surged between August 18 and 25, with Wordfence blocking more than 250,000 attempts. Attackers have deployed a PHP webshell named `Mushr00w_upl.php`. Administrators should immediately upgrade to Super Forms `6.3.314`, released July 8, and investigate web roots and upload directories for unexpected PHP files and suspicious requests to the plugin's vulnerable AJAX endpoint.
