The European VAT Compliance Assistant for WooCommerce plugin for WordPress contains a stored cross-site scripting (XSS) vulnerability via the CF-IPCountry header in all versions up to and including 1.36.10. This vulnerability allows unauthenticated attackers to inject malicious scripts that are stored in order post-meta during guest checkouts and executed when users access the affected pages.
The Redux Framework WordPress plugin up to version 4.5.11 contains a privilege escalation vulnerability. Authenticated users with Subscriber-level access or higher can exploit insufficient capability checks to set arbitrary user roles, including Administrator, during profile updates if a plugin or theme uses certain Redux user profile fields. This vulnerability arises from saving arbitrary meta keys under a registered option without proper restrictions.
The Redux Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via User Meta Merge via 'user-mediaurl' Media Field in all versions up to, and including, 4.5.14 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by Subscriber-level users who can store a payload in user meta fields such as the biography, session_tokens (via a crafted User-Agent at login), or persisted_preferences (via the REST API), which are then promoted to the site-wide redux_demo option when a media URL repair is triggered on the demo panel.
The Redux Framework WordPress plugin up to version 4.5.14 contains an authorization bypass vulnerability. Authenticated users with subscriber-level access or higher can delete arbitrary media library attachments, including those owned by administrators. This occurs because the plugin does not properly verify user authorization when a Custom Fonts field is registered on the user profile page, exposing a nonce that enables this action.
The Redux Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the spinner field in versions up to, and including, 4.5.13 This is due to insufficient input sanitization and output escaping. In the user_meta_save() function scalar values bypass the sanitization logic that only processes arrays, allowing the spinner field value to be stored in user meta without proper sanitization. Later, at line 56 of class-redux-spinner.php in the render() function, this value is rendered in an unquoted HTML attribute without escaping via '$data_string .= ' data-val=' . $this->value;'. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Redux Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Media field filter values in versions up to, and including, 4.5.13 This is due to insufficient input sanitization of nested array values in the user_meta_save() function and unsafe output of filter CSS values in the render() function without proper escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Redux Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Slider field in User Profile settings in versions up to and including 4.5.13.1. This is due to insufficient input sanitization in the user_meta_save() function (which only sanitizes array values, not scalar values) and improper output escaping in the Redux_Slider::render() method, which outputs slider values into unquoted HTML attributes. The vulnerability also exploits the fact that the clean_default() method only casts values to numeric types when they are empty or out of bounds, allowing malicious strings like '1 tabindex=0 autofocus onfocus=alert(1) x=' to pass validation through PHP's loose type comparison. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts into their user profile that will execute whenever an Administrator navigates to view the attacker's profile page.
The UpdraftPlus: WP Backup & Migration Plugin plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.26.4 via the UpdraftPlus_Remote_Communications_V2::wp_loaded function. This is due to insufficient validation of the remote communications message format, where signature verification can be bypassed and unchecked decryption return values collapse to a predictable all-zero encryption key. This makes it possible for unauthenticated attackers to forge arbitrary RPC commands and run them as the connected administrator, such as uploading and activating a malicious plugin, which ultimately leads to remote code execution.
The All-In-One Security (AIOS) – Security and Firewall WordPress plugin is vulnerable to a stored cross-site scripting (XSS) flaw in versions up to and including 5.4.7. This occurs when specific features are enabled, allowing unauthenticated attackers to inject malicious scripts into debug logs. These scripts execute in the administrator's browser when viewing the debug log page, potentially leading to site compromise.
The Easy Updates Manager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'paged' parameter in versions up to, and including, 9.0.20 This is due to insufficient input sanitization and output escaping in the pagination() function. This makes it possible for attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page granted they can trick an administrator into performing an action such as clicking on a link.
A path traversal vulnerability (CWE-22) exists in the WP-Optimize WordPress plugin up to version 4.5.2, allowing authenticated users with author-level access or higher to delete arbitrary files on the server. This occurs due to insufficient validation of the 'original-file' meta key in the unscheduled_original_file_deletion function. Because the meta key is public and modifiable by authors, attackers can exploit this to delete critical files such as wp-config.php, potentially leading to remote code execution. The vulnerability has a high severity with a CVSS score of 8.1. No official patch or remediation guidance is currently available from the vendor. No known exploits are reported in the wild at this time.
The WP-Optimize plugin for WordPress is vulnerable to unauthorized access of functionality due to missing capability checks in the `receive_heartbeat()` function in `includes/class-wp-optimize-heartbeat.php` in all versions up to, and including, 4.5.0. This is due to the Heartbeat handler directly invoking `Updraft_Smush_Manager_Commands` methods without verifying user capabilities, nonce tokens, or the allowed commands whitelist that the normal AJAX handler (`updraft_smush_ajax`) enforces. This makes it possible for authenticated attackers, with Subscriber-level access and above, to invoke admin-only Smush operations including reading log files (`get_smush_logs`), deleting all backup images (`clean_all_backup_images`), triggering bulk image processing (`process_bulk_smush`), and modifying Smush options (`update_smush_options`).
The Redux Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘data’ parameter in all versions up to, and including, 4.5.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The WPGet API – Connect to any external REST API plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 2.2.10. This makes it possible for authenticated attackers, with Administrator-level access and above, to make web requests to arbitrary locations originating from the web application which can be used to query and modify information from internal services.
The UpdraftPlus: WP Backup & Migration Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the showdata and initiate_restore parameters in all versions up to, and including, 1.24.12 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick an admin user into performing an action such as clicking on a link.
The UpdraftPlus: WP Backup & Migration Plugin plugin for WordPress is vulnerable to PHP Object Injection in all versions from 1.23.8 to 1.24.11 via deserialization of untrusted input in the 'recursive_unserialized_replace' function. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. An administrator must perform a search and replace action to trigger the exploit.
The Redux Framework plugin for WordPress is vulnerable to unauthenticated JSON file uploads due to missing authorization and capability checks on the Redux_Color_Scheme_Import function in versions 4.4.12 to 4.4.17. This makes it possible for unauthenticated attackers to upload JSON files, which can be used to conduct stored cross-site scripting attacks and, in some rare cases, when the wp_filesystem fails to initialize - to Remote Code Execution.
The Testimonial Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'testimonialcategory' shortcode in all versions up to, and including, 1.3.2 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Internal Link Juicer: SEO Auto Linker for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings such as 'ilj_settings_field_links_per_page' in all versions up to, and including, 2.23.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
The All-In-One Security (AIOS) – Security and Firewall plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'tab' parameter in all versions up to, and including, 5.2.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
