Is WPLP Cookie Consent safe? Known vulnerabilities and latest version

Unauthenticated Cross Site Scripting (XSS) in WP Cookie Notice for GDPR, CCPA & ePrivacy Consent <= 4.4.6 versions.

The WPLP Cookie Consent WordPress plugin before 4.4.4 does not escape a value submitted through a public endpoint for the JavaScript context it is later output in on an administrative screen, allowing unauthenticated users to run arbitrary JavaScript in the session of an administrator who interacts with the logged entry. Only multisite installations are affected.

The WPLP Cookie Consent WordPress plugin before 4.4.4 does not perform CSRF or capability checks when processing bulk actions on its administration screens, and does not restrict the targeted items to its own records, allowing attackers to make a logged in admin permanently delete arbitrary posts and pages via a crafted request.

The Cookie Banner for GDPR / CCPA – WPLP Cookie Consent plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpl_user_preference' parameter in all versions up to, and including, 4.4.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The consent-logging AJAX endpoint is registered for unauthenticated users and its required nonce (wpl_consent_logging_nonce) is publicly emitted via wp_localize_script on the frontend, meaning any unauthenticated site visitor can plant a payload without any prior authentication or privileged access.

The WPLP Cookie Consent WordPress plugin before 4.4.2 does not perform nonce or capability checks on one of its cookie scanner AJAX actions, allowing any authenticated user, such as a subscriber, to read back the automated scan schedule the administrator configured.

The WPLP Cookie Consent WordPress plugin before 4.4.2 does not perform nonce or capability checks on several of its settings AJAX actions, allowing any authenticated user, such as a subscriber, to read and destroy scan data belonging to the administrator and to overwrite the WPLP Cookie Consent WordPress plugin before 4.4.2's stored configuration.

The WPLP Cookie Consent WordPress plugin before 4.4.2 does not have any authorisation or CSRF checks when storing visitor consent state, and the code that does so runs on every front-end page load, allowing unauthenticated attackers to overwrite a site-wide option with arbitrary data.

The WPLP Cookie Consent WordPress plugin before 4.4.2 does not have capability or nonce checks on some of its A/B testing actions, allowing any authenticated user, such as a subscriber, to overwrite the cookie banner configuration shown to every visitor and to irreversibly reset the stored A/B test results.

The WPLP Cookie Consent WordPress plugin before 4.4.2 does not properly validate a pagination parameter before using it in a SQL query, allowing users with administrator privileges to perform SQL injection attacks.

The WPLP Cookie Consent – Cookie Banner & Consent Management for GDPR, CCPA & Google Consent Mode plugin for WordPress is vulnerable to arbitrary file upload due to missing file type validation in the saas_upload_logo() function combined with an authorization bypass on the WPLP connector REST endpoints in all versions up to, and including, 4.4.1. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

The Cookie Banner for GDPR / CCPA – WPLP Cookie Consent plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'regionArray' parameter in all versions up to, and including, 4.3.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires that the site administrator has enabled the 'Support Google Consent Mode (GCM)' setting, which is disabled by default. Additionally, the AJAX handler performs no nonce or capability check, allowing any authenticated user including those with Subscriber-level access to overwrite the affected plugin setting.

The Cookie Banner for GDPR / CCPA – WPLP Cookie Consent plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.3.7. This is due to missing or incorrect nonce validation on the process_bulk_action function.

The Cookie Banner for GDPR / CCPA – WPLP Cookie Consent plugin for WordPress is vulnerable to generic SQL Injection via the 'scan_id' parameter in all versions up to, and including, 4.3.6 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The GDPR Cookie Consent plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and missing nonce verification on the gdpr_cookie_consent_ajax_save_schedule_scan() function (the wp_ajax_gcc_save_schedule_scan AJAX action) in versions up to, and including, 4.3.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the plugin's cookie scan schedule configuration stored in the gdpr_scan_schedule_data option, which is an administrative function intended to be limited to users with the manage_options capability.

The GDPR Cookie Consent plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'gdpr/v1/settings' REST API endpoint in all versions up to, and including, 4.1.2.
