Descrição técnica

The Anti-Spam by CleanTalk – Spam Protection Without CAPTCHA plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 6.88 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 is exploitable once a comment from the attacker's email address has been approved; on default WordPress installations, only the first comment from a given email address is held for moderation, meaning subsequent comments auto-approve and immediately expose the payload to site visitors.

———The RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'item_title (parsed from feed <item><title>)' parameter in all versions up to, and including, 5.2.13 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 requires an administrator to have previously configured a Feed-to-Post import pointing at an attacker-controlled feed URL, after which the attacker can rotate payloads at will without any further interaction with the site.6h CVE-2026-1192114.9 MÉD

———The AAA Autoload Optimizer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'option_page' parameter in all versions up to, and including, 1.7.0 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. Exploitation requires the plugin's Option Tracking setting to be configured to 'Legacy' mode, and succeeds despite WordPress ultimately returning HTTP 403 to the low-privileged caller because the vulnerable 'all' filter fires before the capability check in wp-admin/options.php.6h CVE-2026-1191785.4 MÉD

———The Smart Cookie Kit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 2.3.2 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 payload is specifically crafted to survive wp_kses on save by storing hostile characters inside allowed HTML elements, with the attribute-breaking double-quote smuggled inside a permitted <code> body and reconstructed into a <abbr title> attribute only at render time by the plugin's own output buffer; exploitation requires an administrator to approve the comment and subsequently view the affected public post.6h
