CVE-2025-64256: 
WordPress vulnerability analysis and mitigation

CVE-2025-64256 is a Cross-Site Request Forgery (CSRF) vulnerability in the PressTigers Simple Folio WordPress plugin. It affects all versions of the plugin up to and including version 1.1.0. The vulnerability was published on December 9, 2025, and was assigned by Patchstack. It carries a CVSS v3.1 base score of 8.8 (High) (Feedly, Patchstack).

The vulnerability is classified as CWE-352 (Cross-Site Request Forgery), meaning the plugin fails to properly validate or verify the origin of state-changing requests made by authenticated users. An attacker can craft a malicious web page or link that, when visited by an authenticated WordPress user with sufficient privileges, silently submits forged requests to the vulnerable plugin's endpoints. Exploitation requires no special privileges from the attacker but does require user interaction — specifically, tricking an authenticated user into visiting a malicious URL or page (Feedly).

Successful exploitation allows an attacker to perform unauthorized actions on behalf of an authenticated WordPress user without their knowledge or consent. This can include modifying plugin settings, altering user permissions, deleting portfolio content, or otherwise compromising the integrity of the WordPress site. Given the CVSS scores of High for confidentiality, integrity, and availability, a successful attack could result in significant site compromise (Feedly).

There is currently no public proof-of-concept exploit available, and no evidence of active in-the-wild exploitation has been observed. The EPSS score is extremely low at approximately 0.008%, indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog (Feedly).

1. Reconnaissance: Identify WordPress sites running the Simple Folio plugin version 1.1.0 or earlier, which can be detected via plugin enumeration tools or by inspecting publicly accessible WordPress sites.
2. Craft malicious request: Create a forged HTML form or JavaScript-based request targeting a state-changing endpoint in the Simple Folio plugin (e.g., a settings update or content modification action).
3. Social engineering: Deliver the malicious page or link to an authenticated WordPress administrator or editor via phishing email, forum post, or other social engineering vector.
4. Trigger CSRF: When the authenticated victim visits the attacker-controlled page, the browser automatically submits the forged request to the WordPress site, carrying the victim's session cookies.
5. Achieve objective: The plugin processes the forged request as legitimate, allowing the attacker to modify plugin settings, alter permissions, or delete content without the victim's knowledge (Feedly).

• Logs: Unexpected POST requests to Simple Folio plugin admin endpoints in WordPress access logs, particularly from unusual referrer URLs or with no referrer header.
• File System: Unexplained changes to Simple Folio plugin configuration files or WordPress database entries related to the plugin's settings.
• Logs: WordPress audit logs (if enabled) showing plugin setting changes or content modifications attributed to an authenticated user who denies making them.

Users should immediately update the Simple Folio WordPress plugin to the latest available version beyond 1.1.0, which should include proper CSRF nonce validation. As interim mitigations, administrators can restrict access to the WordPress admin panel by IP allowlisting, use a WordPress security plugin that adds CSRF protection, and educate users about the risks of clicking unsolicited links while logged into WordPress. Strict session management and enforcing logout when not in use can also reduce exposure (Feedly, Patchstack).
