May 5, 2026EmailKit: Arbitrary File ReadCVE-2026-5957 · WordPress plugins & themes · reported by WordfenceMedium 6.5
The EmailKit plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to and including 1.6.5. This is due to a flawed path traversal validation in the create_template() method of the CheckForm class, where realpath() is called on the allowed base directory (wp-content/uploads/emailkit/templates/) which may not exist, causing it to return false. In PHP 8.x, strpos($real_path, false) implicitly converts false to an empty string, and strpos() with an empty needle always returns 0, causing the check strpos(...) !== 0 to evaluate to false and bypassing the path validation entirely. This makes it possible for authenticated attackers, with Author-level access and above, to read arbitrary files from the server, including sensitive files such as wp-config.php, by supplying an absolute path to the emailkit-editor-template REST API parameter.

Apr 24, 2026MailKit is a cross-platform mail client library built on top of MimeKit.CVE-2026-41319 · Other software · jstedfast · reported by GitHubMedium 6.5
MailKit is a cross-platform mail client library built on top of MimeKit. A STARTTLS Response Injection vulnerability in versions prior to 4.16.0 allows a Man-in-the-Middle attacker to inject arbitrary protocol responses across the plaintext-to-TLS trust boundary, enabling SASL authentication mechanism downgrade (e.g., forcing PLAIN instead of SCRAM-SHA-256). The internal read buffer in `SmtpStream`, `ImapStream`, and `Pop3Stream` is not flushed when the underlying stream is replaced with `SslStream` during STARTTLS upgrade, causing pre-TLS attacker-injected data to be processed as trusted post-TLS responses. Version 4.16.0 patches the issue.

Mar 20, 2026EmailKit – Email Customizer for WooCommerce & WP: Arbitrary file readCVE-2026-3474 · WordPress plugins & themes · reported by WordfenceMedium 4.9
The EmailKit – Email Customizer for WooCommerce & WP plugin for WordPress is vulnerable to arbitrary file read via path traversal in all versions up to, and including, 1.6.3. This is due to the action() function in the TemplateData class passing user-supplied input from the 'emailkit-editor-template' REST API parameter directly to file_get_contents() without any path validation, sanitization, or restriction to an allowed directory. This makes it possible for authenticated attackers, with Administrator-level access, to read arbitrary files on the server (such as /etc/passwd or wp-config.php) by supplying a traversal path. The file contents are stored as post meta and can subsequently be retrieved via the fetch-data REST API endpoint. Notably, the CheckForm class in the same plugin implements proper path validation using realpath() and directory restriction, demonstrating that the developer was aware of the risk but failed to apply the same protections to the TemplateData endpoint.

Feb 18, 2026EmailKit – Email Customizer for WooCommerce & WP: Unauthorized data modificationCVE-2026-1925 · WordPress plugins & themes · reported by WordfenceMedium 4.3
The EmailKit – Email Customizer for WooCommerce & WP plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check on the 'update_template_data' function in all versions up to, and including, 1.6.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the title of any post on the site, including posts, pages, and custom post types.

Jan 7, 2026EmailKit: Arbitrary File ReadCVE-2025-14059 · WordPress plugins & themes · reported by WordfenceMedium 6.5
The EmailKit plugin for WordPress is vulnerable to Arbitrary File Read via Path Traversal in all versions up to, and including, 1.6.1. This is due to missing path validation in the create_template REST API endpoint where user-controlled input from the emailkit-editor-template parameter is passed directly to file_get_contents() without sanitization. This makes it possible for authenticated attackers with Author-level permissions or higher to read arbitrary files on the server, including sensitive configuration files like /etc/passwd and wp-config.php, via the REST API. The file contents are stored in post meta and can be exfiltrated through MetForm's email confirmation feature.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. 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. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
