CVE-2025-57893: 
WordPress vulnerability analysis and mitigation

CVE-2025-57893 is a Cross-Site Request Forgery (CSRF) vulnerability in the Epsiloncool WP Fast Total Search plugin for WordPress. It affects all versions through 1.79.270 and was discovered by researcher Nabil Irawan, reported on July 19, 2025, and publicly disclosed on August 22, 2025. The vulnerability carries a CVSS v3.1 base score of 4.3 (Medium) (Patchstack, Red Hat CVE).

The vulnerability is classified as CWE-352 (Cross-Site Request Forgery) and stems from missing or insufficient CSRF token validation in the WP Fast Total Search plugin's request handling. An unauthenticated attacker can craft a malicious web page or link that, when visited by an authenticated WordPress administrator or privileged user, triggers unauthorized state-changing actions on the target site without the user's knowledge. Exploitation requires user interaction — specifically, a privileged user must be tricked into clicking a malicious link or visiting a crafted page (Patchstack).

Successful exploitation allows a malicious actor to force higher-privileged WordPress users to execute unwanted administrative actions under their current authentication session, resulting in unauthorized integrity modifications to the site. The confidentiality and availability impacts are rated as none, with only a low integrity impact, meaning attackers cannot directly read sensitive data or cause service disruption but may alter plugin settings or site configuration. The scope is limited to the affected WordPress installation (Patchstack).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported for CVE-2025-57893. The EPSS score is approximately 0.014% (0.000140), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. Patchstack classifies this as low priority with no impactful threat, though they note that CSRF vulnerabilities of this type can be used in mass-exploit campaigns targeting WordPress sites at scale (Patchstack).

1. Reconnaissance: Identify WordPress sites running the WP Fast Total Search plugin at version 1.79.270 or earlier, using tools like WPScan or passive enumeration of plugin directories.
2. Craft malicious payload: Create an HTML page or form that automatically submits a forged HTTP request to the target WordPress site's plugin endpoint, targeting a state-changing action (e.g., modifying plugin settings) without a valid CSRF nonce.
3. Social engineering: Deliver the malicious link or page to an authenticated WordPress administrator via phishing email, comment, or other social engineering vector.
4. Trigger exploitation: When the administrator visits the crafted page while logged into the WordPress site, their browser automatically sends the forged request with their session credentials, causing the unauthorized action to execute on the server (Patchstack).

The vulnerability is patched in WP Fast Total Search version 1.79.274. WordPress site administrators should update the plugin to version 1.79.274 or later immediately. Patchstack users can enable auto-update for vulnerable plugins as an additional safeguard. No specific configuration-based workaround has been published; upgrading is the recommended and only confirmed remediation (Patchstack).
