CVE-2025-58831 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the snagysandor Parallax Scrolling Enllax.js library, specifically affecting versions up to 0.0.6. Enllax.js is a JavaScript library used to implement parallax scrolling effects on websites, enhancing user interface aesthetics. The vulnerability arises because the library does not implement adequate CSRF protections, allowing an attacker to trick an authenticated user into submitting unwanted requests to a web application that uses this library. Although the vulnerability itself is in a front-end JavaScript library, the impact depends on how the library is integrated within a web application and whether the application processes state-changing requests without proper anti-CSRF tokens or validation. The CVSS v3.1 score is 4.3 (medium severity), with the vector indicating that the attack can be performed remotely (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The impact is limited to integrity (I:L) with no confidentiality or availability impact. No known exploits are currently in the wild, and no patches have been published yet. The vulnerability is classified under CWE-352, which covers CSRF issues where unauthorized commands are transmitted from a user that the web application trusts. Since Enllax.js is a client-side library, the vulnerability's exploitation depends heavily on the server-side implementation and whether the server validates requests properly. The lack of patch links suggests that remediation may require developers to implement or enhance CSRF protections in their applications or update the library once a fix is available.

For European organizations, the primary risk of this vulnerability lies in web applications that incorporate the Enllax.js library without sufficient CSRF protections. Successful exploitation could allow attackers to perform unauthorized actions on behalf of authenticated users, potentially leading to data integrity issues such as unauthorized changes to user settings, content, or transactions. While the vulnerability does not directly compromise confidentiality or availability, the integrity impact can still disrupt business operations or damage trust. Organizations in sectors with high web presence—such as e-commerce, government portals, and online services—are more at risk if they use this library. The medium severity score reflects that exploitation requires user interaction and does not grant full control or data leakage but still poses a meaningful threat if leveraged in targeted attacks. Since no known exploits exist yet, the immediate risk is moderate, but organizations should proactively assess their exposure and implement mitigations to prevent future exploitation.

1. Web developers should audit their applications to identify usage of the Enllax.js library, especially versions up to 0.0.6. 2. Implement robust CSRF protections on the server side, including the use of anti-CSRF tokens for all state-changing requests, regardless of client-side libraries. 3. Employ SameSite cookie attributes to restrict cross-origin requests where applicable. 4. Monitor for updates or patches from the snagysandor project and plan to upgrade the Enllax.js library once a fix is released. 5. Educate users about phishing and social engineering risks to reduce the likelihood of successful CSRF attacks requiring user interaction. 6. Conduct security testing, including CSRF attack simulations, to validate the effectiveness of implemented protections. 7. Consider Content Security Policy (CSP) headers to limit the sources of executable scripts, reducing the attack surface. 8. If immediate patching is not possible, consider removing or replacing the Enllax.js library with alternative solutions that follow secure coding practices.
