  • Jun 24, 2026ARForms: Stored Cross-Site ScriptingCVE-2026-3652 · WordPress plugins & themes · reported by WordfenceHigh 7.2

    The ARForms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `value` parameter of the `arf_save_incomplete_form_data` AJAX action in all versions up to, and including, 7.1.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that will execute whenever an administrator views the "Partial Filled Form Entries" page in the ARForms dashboard.

  • Jun 19, 2026Database for Contact Form 7, WPforms, Elementor forms: Arbitrary file deletionCVE-2026-9843 · WordPress plugins & themes · reported by WordfenceHigh 8.1

    The Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the view_page function in all versions up to, and including, 1.5.1. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Successful exploitation requires an administrator to view or edit the poisoned form entry, at which point PHP's bracket parser reshapes the attacker-crafted JSON key to bypass the stored-path isset check and trigger deletion of the traversal-specified file.

    The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.3.6 via the 'return_type' parameter. This makes it possible for unauthenticated attackers to extract sensitive data including the plaintext post_password of password-protected courses and the full post_content, post_author, and post_name of unpublished draft, private, and pending courses via the unrestricted SELECT * fallback query. Exploitation requires supplying both c_status=all (to bypass the publish-only post_status WHERE clause) and return_type=json (to prevent the safe DISTINCT(ID) AS ID field override) in a single unauthenticated request to the /wp-json/lp/v1/courses/archive-course endpoint.

  • Jun 6, 2026WPForms – Easy Form Builder for WordPress – Contact Forms, Payment Forms, Surveys, & More: Insufficient Verification of Data AuthenticityCVE-2026-7792 · WordPress plugins & themes · reported by WordfenceMedium 5.3

    The WPForms – Easy Form Builder for WordPress – Contact Forms, Payment Forms, Surveys, & More plugin for WordPress is vulnerable to Insufficient Verification of Data Authenticity in versions up to and including 1.10.0.1. This is due to the PayPal Commerce webhook endpoint processing unauthenticated JSON webhook payloads without verifying that the request originated from PayPal using the required HMAC-SHA256 webhook signature, and only checking whether the supplied event_type is whitelisted before dispatching the attacker-controlled resource data to handlers that update payment records. This makes it possible for unauthenticated attackers who know a valid PayPal subscription_id to forge PayPal webhook events and modify subscription payment records, such as reactivating a cancelled or suspended subscription by setting its subscription_status to active.

Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories.
