CVE-2025-62089: 
WordPress vulnerability analysis and mitigation

CVE-2025-62089 is a Cross-Site Request Forgery (CSRF) vulnerability in the MERGADO Mergado Pack WordPress plugin (mergado-marketing-pack). It affects all versions through 4.2.1 and allows unauthenticated attackers to trick authenticated users into performing unauthorized actions on the plugin's configuration or settings. The vulnerability was reported by Muhammad Nur Ibnu Hubab on October 24, 2025, and publicly disclosed by Patchstack on December 31, 2025. It carries a CVSS v3.1 base score of 4.3 (Medium), assigned by Patchstack (Patchstack).

The vulnerability is classified as CWE-352 (Cross-Site Request Forgery) and stems from missing or insufficient CSRF token validation on one or more plugin action endpoints within the Mergado Pack WordPress plugin (Patchstack). An unauthenticated attacker can craft a malicious web page or link that, when visited by an authenticated WordPress administrator or privileged user, silently submits a forged request to the vulnerable endpoint using the victim's active session. No special privileges are required by the attacker; however, user interaction from a privileged user is necessary for exploitation. The attack vector is network-based with low complexity, aligning with OWASP Top 10 category A1: Broken Access Control (Patchstack).

Successful exploitation allows an attacker to manipulate authenticated users into modifying Mergado Pack plugin configurations or settings without their knowledge or consent (Feedly). The integrity impact is limited (low), with no direct confidentiality or availability impact, meaning attackers cannot directly read sensitive data or cause service disruption through this vulnerability alone. However, unauthorized changes to marketing pack settings (e.g., feed configurations, tracking integrations) could indirectly affect e-commerce operations or introduce malicious tracking parameters on affected WordPress/WooCommerce sites (Patchstack).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported for CVE-2025-62089. The EPSS score is approximately 0.014% (0.000140), indicating a very low probability of exploitation in the near term (Feedly). The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack classifies this as low priority, noting it is unlikely to be exploited despite CSRF vulnerabilities sometimes being used in mass-exploit campaigns targeting WordPress plugins (Patchstack).

1. Reconnaissance: Identify WordPress sites running the Mergado Pack plugin in versions ≤ 4.2.1 using tools like WPScan or by inspecting publicly accessible plugin metadata.
2. Identify vulnerable endpoint: Determine which plugin action endpoint lacks CSRF token validation (e.g., a settings update or configuration form handler within the Mergado Pack admin interface).
3. Craft malicious request: Create an HTML page or form that auto-submits a POST request to the vulnerable WordPress admin endpoint (e.g., wp-admin/admin-post.php or a plugin-specific action URL) with attacker-controlled parameter values.
4. Deliver to victim: Trick an authenticated WordPress administrator into visiting the malicious page via phishing email, social engineering, or embedding in a compromised site.
5. Unauthorized action executed: The victim's browser automatically submits the forged request using their active session cookie, causing the plugin settings to be modified without the administrator's awareness (Patchstack).

• Logs: WordPress access logs showing unexpected POST requests to Mergado Pack admin action endpoints from unusual referrer URLs or external domains.
• Application: Unexplained changes to Mergado Pack plugin settings or feed configurations in the WordPress admin panel without corresponding administrator activity.
• Network: Requests to WordPress admin endpoints originating from non-administrative IP addresses or unusual geographic locations coinciding with an administrator session.

As of the disclosure date (December 31, 2025), Patchstack reports no official patch is available from the vendor, and all versions through 4.2.1 remain vulnerable (Patchstack). Site administrators should monitor the WordPress plugin repository for an updated version from MERGADO and apply it as soon as one is released. In the interim, consider deactivating the plugin if it is not critical to operations, or use a WordPress security plugin (such as Patchstack) that provides virtual patching to block CSRF exploitation attempts. Administrators should also exercise caution when clicking links or visiting external pages while logged into the WordPress admin panel.

The vulnerability was discovered by independent researcher Muhammad Nur Ibnu Hubab and responsibly disclosed through Patchstack's vulnerability disclosure program (Patchstack). No significant vendor statements, notable researcher commentary, or broader media coverage have been identified for this low-severity vulnerability.
