CVE-2025-64256 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the PressTigers Simple Folio product, affecting versions up to 1.1.0. CSRF vulnerabilities occur when a web application does not sufficiently verify that requests made to it originate from an authenticated and authorized user, allowing attackers to craft malicious web pages or links that cause authenticated users to unknowingly perform actions such as changing settings, submitting forms, or modifying data. In this case, Simple Folio lacks adequate CSRF protections, such as anti-CSRF tokens or origin checks, enabling attackers to exploit this flaw by tricking logged-in users into sending forged requests. The vulnerability does not require the attacker to have direct access or elevated privileges; the victim must simply be authenticated and visit a malicious site. No CVSS score is assigned yet, and no public exploits have been reported, but the vulnerability is publicly disclosed and considered exploitable. The absence of patches at the time of publication indicates that users must implement interim mitigations. This vulnerability threatens the integrity of user actions and could lead to unauthorized modifications within the Simple Folio environment, potentially impacting data accuracy and trustworthiness.

For European organizations, the CSRF vulnerability in Simple Folio could lead to unauthorized changes to portfolio content, user settings, or other critical data managed by the application. This can result in data integrity issues, loss of user trust, and potential disruption of business operations, especially for companies relying on Simple Folio for client-facing or internal content management. Attackers could manipulate user actions to deface portfolios, inject malicious content, or alter configurations, which might also affect compliance with data protection regulations like GDPR if personal data is involved. The impact is particularly significant for creative agencies, marketing firms, and digital content providers prevalent in Europe that utilize Simple Folio. Although availability and confidentiality impacts are limited, the integrity compromise and potential reputational damage are substantial. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits following public disclosure.

European organizations using Simple Folio should immediately implement several specific mitigations: 1) Apply any official patches or updates from PressTigers as soon as they become available. 2) If patches are not yet released, implement server-side anti-CSRF tokens in all state-changing forms and requests to ensure that only legitimate user actions are processed. 3) Enforce strict validation of the HTTP Referer and Origin headers to block requests originating from unauthorized domains. 4) Educate users about the risks of clicking unknown links while authenticated and encourage the use of separate browsers or profiles for sensitive applications. 5) Monitor application logs for unusual or unauthorized actions that could indicate exploitation attempts. 6) Consider deploying Web Application Firewalls (WAFs) with rules to detect and block CSRF attack patterns. 7) Review and minimize user privileges within Simple Folio to reduce the impact of potential CSRF attacks. These targeted steps go beyond generic advice and address the specific nature of the vulnerability.
