CVE-2025-68082: 
WordPress vulnerability analysis and mitigation

CVE-2025-68082 is a Cross-Site Request Forgery (CSRF) vulnerability in the Semrush Content Toolkit WordPress plugin developed by SEMrush CY LTD. It affects all versions of the plugin up to and including 1.1.32, with version 1.1.33 containing the fix. The vulnerability was reported by researcher Nabil Irawan on November 16, 2025, and publicly disclosed on December 15–16, 2025. It carries a CVSS v3.1 base score of 5.4 (Medium), as assessed by Patchstack (Patchstack).

The vulnerability is classified as CWE-352 (Cross-Site Request Forgery), meaning the plugin fails to properly validate the origin of state-changing HTTP requests. An unauthenticated attacker can craft a malicious web page or link that, when visited by an authenticated WordPress user (such as an administrator), causes the victim's browser to submit unauthorized requests to the plugin's endpoints on their behalf. Exploitation requires user interaction — specifically, a privileged user must be tricked into clicking a malicious link or visiting a crafted page while authenticated to the WordPress site (Patchstack).

Successful exploitation allows a malicious actor to force higher-privileged WordPress users to execute unwanted actions under their current authentication context, such as modifying plugin settings or triggering plugin functionality without consent. The CVSS assessment indicates low integrity and low availability impact with no confidentiality impact, limiting the scope to unauthorized state changes within the plugin rather than full site compromise. The vulnerability does not enable direct data exfiltration or remote code execution on its own (Patchstack).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported for CVE-2025-68082. The EPSS score is extremely low at 0.000080, indicating a very low probability of exploitation in the near term. 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 against WordPress sites (Patchstack).

1. Reconnaissance: Identify WordPress sites running the Semrush Content Toolkit plugin version 1.1.32 or earlier, using tools like WPScan or by inspecting publicly accessible plugin metadata.
2. Craft malicious payload: Create an HTML page or form that automatically submits a forged HTTP request to the vulnerable plugin endpoint on the target WordPress site (e.g., an admin action URL), without including a valid CSRF nonce.
3. Social engineering: Deliver the malicious link or page to a target WordPress user with sufficient privileges (e.g., administrator) via phishing email, forum post, or other social engineering vector.
4. Trigger exploitation: When the authenticated victim visits the attacker-controlled page, their browser automatically submits the forged request to the WordPress site, executing the unauthorized action under the victim's session.
5. Achieve objective: The plugin processes the forged request as legitimate, potentially modifying plugin settings or triggering plugin functionality as dictated by the attacker (Patchstack).

• Logs: WordPress access logs showing unexpected POST requests to Semrush Content Toolkit plugin endpoints from unusual referrer origins or with missing/invalid nonce parameters.
• Logs: Admin action logs reflecting plugin configuration changes that the legitimate administrator did not intentionally perform.
• Network: HTTP requests to WordPress admin-ajax.php or plugin-specific endpoints originating from external or unexpected referrer domains.

The primary remediation is to update the Semrush Content Toolkit plugin to version 1.1.33 or later, which contains the fix for this CSRF vulnerability. No configuration-based workaround has been published; updating the plugin is the only recommended solution. WordPress site administrators using Patchstack can enable auto-update for vulnerable plugins to receive protection automatically (Patchstack).

The vulnerability received minimal public attention, consistent with its low severity rating. Patchstack, the disclosing CNA, characterized it as low priority and unlikely to be exploited. No notable researcher commentary, vendor statements beyond the advisory, or significant media coverage has been identified for this CVE.
