What happened

CVE-2026-14494 affects The Sigma Forms Pro plugin for WordPress is vulnerable to Remote Code Execution in all up to, and including, 1 4 5 via the handle_form_submis The Sigma Forms Pro plugin for WordPress. A security weakness in The Sigma Forms Pro plugin for WordPress is vulnerable to Remote Code Execution in all is being tracked as CVE-2026-14494. The Sigma Forms Pro plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1 4 5 via the handle_form_submission function.

The available advisory information identifies up to, and including, 1 4 5 via the handle_form_submis The Sigma Forms Pro plugin for WordPress as affected versions. The available description indicates that the vulnerable path can be reached remotely or from an untrusted network, so the exposure of The Sigma Forms Pro plugin for WordPress is vulnerable to Remote Code Execution in all becomes part of the attack condition. The reported consequence is code execution, meaning successful exploitation could make the affected application or process run attacker-controlled code.

The published description indicates a remote or untrusted-network exploitation path. This is due to the plugin dynamically granting the unfiltered_upload capability to all users during form submissions and bypassing MIME type validation when allowed_file_types is not configured. A maximum-severity vulnerability in the GiveWP plugin for WordPress allows an unauthenticated attacker to execute arbitrary commands on the hosting server.

GiveWP WordPress donation plugin flaw lets hackers execute server commands.

Editorial note: this News Brief follows the available evidence and adds length only when additional facts or useful context are available. Where public reporting does not establish a specific victim sequence, CyberDeltaForce does not present one as fact.
