iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more <= 3.13.6 - Unauthenticated Stored Cross-Site Scripting via Comment Content via IUB-COOKIE-BLOCK Marker

The iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.13.6. This is due to the way iubendaParser::parse_comments() re-processes HTML inside IUB-COOKIE-BLOCK markers through the bundled simple_html_dom parser after WordPress has already KSES-filtered the saved comment: simple_html_dom's remove_noise() stores <code> bodies under a deterministic key ('___noise___ 1000') and restore_noise() later substitutes any matching substring back into attribute values WITHOUT re-escaping, allowing a quote-breaking payload stashed in an allowed <code> element to be injected into an allowed <abbr title="___noise___ 1000"> attribute at render time. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, after an administrator approves the first (otherwise moderated) comment under WordPress's default comment_previously_approved setting.

WordPress iubenda plugin <= 3.13.6 - Denial of Service Attack vulnerability

iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more <= 3.13.4 - Unauthenticated Stored Cross-Site Scripting via Comment Content via AdSense Regex Rewrite

The iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via AdSense Regex Rewrite in all versions up to, and including, 3.13.4 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. This vulnerability only manifests when the 'Secondary' parser engine is active (parser_engine=default); it does not exist under the default 'new' DOM-based parser engine.

iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more <= 3.13.4 - Unauthenticated Stored Cross-Site Scripting via Comment Content

The iubenda | All-in-one Compliance for GDPR / CCPA Cookie Consent + more plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content in all versions up to, and including, 3.13.4 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 exploit works by embedding KSES-allowed markup such as abbr title attributes and HTML comments in a submitted comment so that the global strtr() substitution strips substrings from an inert tag, mutating it into an executable element such as an img onerror handler that runs in the WordPress origin for any visitor, including logged-in administrators.

iubenda < 3.3.3 - Subscriber+ Privileges Escalation to Admin

The iubenda WordPress plugin before 3.3.3 does does not have authorisation and CSRF in an AJAX action, and does not ensure that the options to be updated belong to the plugin as long as they are arrays. As a result, any authenticated users, such as subscriber can grant themselves any privileges, such as edit_plugins etc

The iubenda-cookie-law-solution plugin before 2.3.5 for WordPress does not restrict URL sanitization to http protocols.
