CVE-2026-7795, 6 Jun 2026
The Click to Chat - WA Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the [chat] shortcode 'num' parameter in all versions up to, and including, 4.38. This is due to insufficient escaping when embedding user-supplied shortcode attribute values inside JavaScript string literals that are then placed in HTML event-handler attributes. The CCW_Shortcode::shortcode() function applies esc_attr() to the 'num' parameter (line 157), which converts single quotes to the HTML entity '. This entity-encoded value is then interpolated directly into a JavaScript window.open() call string delimited by single quotes (line 194/221), and that complete string is placed verbatim into an HTML onclick attribute in the style template files (e.g., sc-style-1.php line 6). Because browsers HTML-decode event attribute values before executing the embedded JavaScript, the ' entities are decoded back to literal single quotes at runtime, allowing the injected payload to break out of the JavaScript string context and execute arbitrary code. This makes it possible for authenticated attackers with Contributor-level access and above to inject arbitrary web scripts into pages that will execute whenever a user clicks the WhatsApp chat button rendered by the [chat] shortcode.

CVE-2025-5336, 14 Jun 2025
The Click to Chat plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘data-no_number’ parameter in all versions up to, and including, 4.22 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. CVE record
CVE-2024-3849, 2 May 2024
The Click to Chat - HoliThemes plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 3.35. This makes it possible for authenticated attackers, with contributor access or above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included. CVE record
CVE-2022-4480, 16 Jan 2023
The Click to Chat WordPress plugin before 3.18.1 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins. CVE record

What to do if you run Click to Chat

If you run Click to Chat, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.

If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
