A path traversal vulnerability exists in the Custom Fields WordPress plugin before version 1.5.1. This flaw allows unauthenticated users to supply arbitrary file paths for deletion without proper validation, enabling deletion of critical files such as wp-config.php. Exploitation of this vulnerability can lead to a full site takeover.

The FormGent plugin for WordPress is vulnerable to unauthorized arbitrary file deletion due to a missing capability check on the /wp-json/formgent/responses/attachments REST API endpoint in all versions up to, and including, 1.9.2 This is due to the REST API route being registered without any authentication middleware in routes/rest/api.php. This makes it possible for unauthenticated attackers to delete arbitrary files within the formgent uploads directory. Additionally, on Linux servers where the wp-content/uploads/formgent directory does not yet exist (the default state after plugin installation), the path traversal protection can be bypassed, enabling deletion of arbitrary files including wp-config.php which can lead to complete site takeover via a fresh WordPress installation.

The SpeedyCache plugin for WordPress is vulnerable to Arbitrary File Read via Path Traversal in all versions up to, and including, 1.3.8. This is due to a mismatch between CSS URL validation (which allows query strings like `.css?...`) and path resolution (which strips query strings), combined with no validation that the resolved file is actually a CSS file. This makes it possible for authenticated attackers, with Administrator-level access and above, to read arbitrary files from the server (including `wp-config.php` and `/etc/passwd`) by injecting crafted `<link>` tags into page content, with the file contents written to publicly accessible cache files.

The Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_sticker function in all versions up to, and including, 2.15.19. This makes it possible for authenticated attackers, with administrator-level access and above, 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). The prefix check intended to restrict deletion to the uploads directory can be bypassed by crafting a URL that begins with the legitimate uploads base URL but embeds ../ traversal sequences in the path portion, as the normalize_sticker function only applies esc_url_raw(), which does not strip ../ sequences, allowing the traversal payload to be stored verbatim in WordPress options.

The WP Foodbakery plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'delete_locations_backup_file_callback' function in all versions up to, and including, 4.9. This makes it possible for authenticated attackers, with subscriber-level access and above, 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).

The pCloud WP Backup plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.0.3 via the wp2pcl_ajax_process_request_inner. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract force generation of a full-site backup archive written to a publicly accessible directory, exposing wp-config.php database credentials, WordPress secret salts, and the complete PHP source tree. The resulting archive is deposited in the plugin's unprotected tmp/ directory at a predictable URL, making the extracted data accessible to unauthenticated visitors once the backup is triggered.

The Uncanny Automator plugin for WordPress up to version 7.3.1.4 contains a deserialization vulnerability that allows unauthenticated attackers to delete arbitrary files on the server. This occurs due to insufficient file path validation in the fr_token function. Exploitation requires a Forminator form linked to an Uncanny Automator recipe configured to allow submissions from 'Everyone', enabling malicious serialized payloads to trigger the vulnerability. The plugin includes a gadget chain internally, so no external libraries are needed for exploitation. This can lead to remote code execution if critical files like wp-config.php are deleted.

NukeViet versions prior to 4.6.00 contain a path traversal vulnerability in the Edit Comment admin function that allows an authenticated administrator to delete arbitrary files within the application root. By injecting a crafted 'attach' parameter with a specific padding and traversal sequence, an attacker can cause deletion of critical files such as 'config.php', leading to application outage. The vulnerability arises from insufficient validation of the 'attach' parameter before file deletion. A fix has been implemented that validates the file path to ensure it remains within the intended upload directory.

The Word Count and Social Shares WordPress plugin through 1.0 does not validate a user-supplied file path before deletion, nor does it have proper authorization or CSRF checks, allowing any authenticated user, such as a Subscriber, to delete arbitrary files on the server, which can lead to a full site takeover (e.g. by deleting wp-config.php).

The Planyo Online Reservation System plugin for WordPress is vulnerable to Server-Side Request Forgery leading to Local File Inclusion in all versions up to, and including, 3.0. The ulap.php file acts as an AJAX proxy and is directly accessible without WordPress bootstrapping or any authentication. The send_http_post() function validates the host of the provided URL against an allowlist that includes 'localhost', but critically fails to validate the URL scheme/protocol. This makes it possible for unauthenticated attackers to supply a file:// URL (e.g., file://localhost/etc/passwd) which bypasses the host allowlist check because parse_url() returns 'localhost' as the host. The URL is then passed to curl_init() or fopen(), both of which support the file:// protocol, allowing the attacker to read arbitrary local files on the server and have their contents returned in the HTTP response. This can lead to disclosure of sensitive files such as /etc/passwd, wp-config.php (containing database credentials and authentication keys), and other server-side files.
