CVE-2025-67349: n/a
A cross-site scripting (XSS) vulnerability was identified in FluentCMS 1.2.3. After logging in as an admin and navigating to the "Add Page" function, the application fails to properly sanitize input in the <head> section, allowing remote attackers to inject arbitrary script tags.
AI Analysis
Technical Summary
CVE-2025-67349 identifies a cross-site scripting (XSS) vulnerability in FluentCMS version 1.2.3, specifically within the 'Add Page' functionality accessible to authenticated administrators. The vulnerability arises because the application fails to properly sanitize user-supplied input in the <head> section of new pages, allowing an attacker with admin credentials to inject arbitrary JavaScript code. This injected script can execute in the context of the admin's browser session, potentially enabling session hijacking, unauthorized actions, or the injection of malicious payloads that compromise the integrity and confidentiality of the CMS environment. The attack vector requires the attacker to be authenticated as an admin, which limits exploitation to insiders or compromised admin accounts. No public exploits are currently known, and no official patches or updates have been linked yet. The lack of a CVSS score suggests the vulnerability is newly published and pending further assessment. The flaw is significant because it affects the core content management functionality, potentially impacting all pages created or edited by admins. The vulnerability highlights the importance of robust input validation and output encoding in web applications, especially in administrative interfaces.
Potential Impact
For European organizations using FluentCMS 1.2.3, this vulnerability could lead to unauthorized script execution within the administrative interface, risking session hijacking, unauthorized content changes, or deployment of further malicious code. This could compromise the confidentiality of sensitive data managed through the CMS, degrade the integrity of published content, and potentially disrupt availability if malicious scripts cause application instability. Given that exploitation requires admin authentication, the threat is elevated in environments with weak credential management or insider threats. Public sector, media, and e-commerce organizations in Europe relying on FluentCMS for content management are particularly vulnerable, as successful exploitation could damage reputation and trust. The absence of known exploits suggests a window of opportunity for defenders to implement mitigations before active attacks emerge.
Mitigation Recommendations
1. Restrict administrative access to trusted personnel and enforce strong authentication mechanisms, including multi-factor authentication (MFA). 2. Implement strict input validation and output encoding on all user-supplied data, especially in the <head> section of pages. 3. Monitor administrative actions and logs for unusual behavior indicative of attempted script injection. 4. If possible, apply web application firewalls (WAFs) with rules to detect and block XSS payloads targeting the CMS admin interface. 5. Isolate the CMS administrative interface behind VPNs or IP whitelisting to reduce exposure. 6. Regularly audit and update CMS software; coordinate with FluentCMS developers or vendors for patches or security advisories. 7. Educate administrators on phishing and credential security to prevent account compromise. 8. Consider temporary disabling or restricting the 'Add Page' function until a patch is available.
