CVE-2026-25319: 
WordPress vulnerability analysis and mitigation

CVE-2026-25319 is a Cross-Site Request Forgery (CSRF) vulnerability in the Zita Elementor Site Library WordPress plugin by wpzita. It affects all versions up to and including 1.6.6, with version 1.6.7 containing the fix. The vulnerability was reported on December 29, 2025, and published on January 28, 2026. It carries a CVSS v3.1 base score of 4.3 (Medium) (Patchstack).

The vulnerability is classified as CWE-352 (Cross-Site Request Forgery) and stems from insufficient or missing nonce verification on one or more plugin actions, allowing forged requests to be submitted on behalf of authenticated users. An attacker can craft a malicious web page or link that, when visited by a logged-in WordPress user, triggers unauthorized actions within the plugin without the user's knowledge. Exploitation requires user interaction — specifically, a privileged user must visit or interact with attacker-controlled content (Patchstack).

Successful exploitation allows a malicious actor to force higher-privileged WordPress users to execute unwanted actions under their current authentication context, potentially leading to unauthorized changes to site content or plugin settings. The vulnerability has no direct confidentiality or availability impact (CVSS scores both as NONE), with only a low integrity impact. The scope is limited to the affected WordPress installation and does not provide a direct path to remote code execution or data exfiltration (Patchstack).

The EPSS score for this vulnerability is approximately 0.008% (0.000080), indicating a very low probability of exploitation in the wild. No public proof-of-concept exploit code, active in-the-wild exploitation, or threat actor attribution has been reported. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack classifies this as low priority with no impactful threat, though it notes that CSRF vulnerabilities of this type can be used in mass-exploit campaigns targeting WordPress sites (Patchstack).

1. Reconnaissance: Identify WordPress sites running the Zita Elementor Site Library plugin version 1.6.6 or earlier, using tools like WPScan or passive enumeration of plugin assets in page source.
2. Craft malicious request: Identify the vulnerable plugin action endpoint (e.g., an admin-facing AJAX action or form handler) that lacks CSRF nonce validation.
3. Create forged page: Build a malicious HTML page containing a hidden form or JavaScript that automatically submits a crafted POST request to the target WordPress site's admin endpoint, invoking the vulnerable plugin action.
4. Deliver to victim: Trick a logged-in WordPress administrator or privileged user into visiting the malicious page via phishing email, social engineering, or a compromised third-party site.
5. Action executed: The victim's browser automatically submits the forged request with their authenticated session cookies, causing the plugin to execute the unauthorized action (e.g., modifying plugin settings or importing site templates) (Patchstack).

• Logs: WordPress access logs showing unexpected POST requests to plugin-related admin-ajax endpoints (e.g., wp-admin/admin-ajax.php) from unusual referrer origins or with no referrer header, particularly for Zita Elementor Site Library actions.
• Application: Unexpected changes to plugin settings, imported site templates, or content modifications that administrators do not recall initiating.
• Network: Requests to WordPress admin endpoints originating from external or unfamiliar domains in server access logs, indicating a possible cross-origin forged submission.

The vendor has released version 1.6.7 of the Zita Elementor Site Library plugin, which patches this vulnerability. Site administrators should update the plugin to version 1.6.7 or later immediately via the WordPress dashboard. If an immediate update is not possible, restricting access to the WordPress admin area (e.g., via IP allowlisting) can reduce exposure. Patchstack users can enable auto-update for vulnerable plugins as an additional safeguard (Patchstack).
