CVE-2026-6089: CWE-918 Server-Side Request Forgery (SSRF) in blendmedia WP CTA – Call Now Button, Sticky Button & Call to Action Builder
The WP CTA plugin for WordPress version 2.1.2 and earlier is vulnerable to Server-Side Request Forgery (SSRF) via the 'sticky_s_media' parameter in imported JSON files. This vulnerability allows authenticated users with Administrator-level access or higher to make arbitrary web requests from the server. The plugin uses insufficient URL validation, permitting requests to internal IP addresses. The response from these requests is saved as WordPress media attachments, enabling full-read SSRF. The CVSS score is 4.9, indicating a medium severity vulnerability.
AI Analysis
Technical Summary
CVE-2026-6089 is a Server-Side Request Forgery vulnerability in the blendmedia WP CTA – Call Now Button, Sticky Button & Call to Action Builder WordPress plugin. The issue arises because the import_sidebars() function processes user-supplied URLs from imported JSON data using file_get_contents() with only FILTER_VALIDATE_URL validation, which does not block internal IP addresses. Authenticated attackers with Administrator privileges can exploit this to make arbitrary HTTP requests from the server to internal or external resources. The response content is saved as a WordPress media attachment, resulting in a full-read SSRF. This affects version 2.1.2 of the plugin.
Potential Impact
An attacker with Administrator-level access can leverage this SSRF vulnerability to make arbitrary HTTP requests originating from the web application server. This can be used to access or query internal services that are otherwise inaccessible externally. The vulnerability allows reading of response content by saving it as media attachments in WordPress, potentially exposing sensitive internal information. There is no indication of integrity or availability impact. The CVSS base score is 4.9 (medium severity), reflecting the confidentiality impact and the requirement for high privileges.
Mitigation Recommendations
No official patch or remediation is currently confirmed for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Administrator-level access to trusted users only and avoid importing JSON files from untrusted sources. Monitor vendor communications for updates regarding an official fix.
