CVE-2025-23504 identifies an authentication bypass vulnerability in the RiceTheme Felan Framework, specifically affecting versions up to and including 1.1.3. The vulnerability arises from the framework's failure to properly enforce authentication checks when alternate paths or channels are used to access protected resources. This means an attacker can circumvent normal login procedures and gain unauthorized access to the application or system components. The flaw is rooted in the framework's routing or access control mechanisms that do not adequately validate user credentials across all possible access vectors. Although no exploits have been reported in the wild, the vulnerability poses a significant risk because authentication bypass can lead to unauthorized data access, privilege escalation, and potential full system compromise depending on the deployment context. The Felan Framework is a web application framework developed by RiceTheme, used primarily for building websites and web applications. The lack of a CVSS score and absence of patches at the time of publication indicate that organizations should proactively monitor vendor communications and prepare to apply fixes. The vulnerability's technical nature suggests that attackers with moderate skill could exploit it without needing user interaction or valid credentials, increasing the threat level. The issue was reserved in January 2025 and published in January 2026, indicating a year-long disclosure process. Given the framework's role in authentication, this vulnerability directly impacts confidentiality and integrity, with potential availability impacts if attackers leverage access to disrupt services.

For European organizations, this vulnerability could lead to unauthorized access to internal or customer-facing web applications built on the Felan Framework. Attackers exploiting this flaw can bypass authentication controls, potentially accessing sensitive data, modifying application behavior, or escalating privileges. This could result in data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and operational disruptions. Organizations in sectors such as finance, healthcare, government, and e-commerce, which rely heavily on secure authentication, are particularly at risk. The absence of known exploits currently provides a window for proactive mitigation, but the risk of future exploitation remains high. Additionally, the impact extends to supply chain security if third-party applications or services incorporate the vulnerable framework. The potential for widespread unauthorized access makes this a critical concern for European entities aiming to maintain robust cybersecurity postures.

1. Monitor RiceTheme's official channels for patches or updates addressing CVE-2025-23504 and apply them promptly once available. 2. Conduct a thorough code review of authentication and access control implementations within applications using the Felan Framework to identify and remediate alternate path vulnerabilities. 3. Implement additional access control layers such as Web Application Firewalls (WAFs) configured to detect and block unusual access patterns or unauthorized requests. 4. Enforce multi-factor authentication (MFA) on all critical systems to reduce the risk of unauthorized access even if authentication bypass is attempted. 5. Restrict network access to management interfaces and sensitive endpoints using network segmentation and IP whitelisting. 6. Perform regular security testing, including penetration testing focused on authentication mechanisms, to detect similar bypass issues. 7. Educate development teams on secure coding practices related to authentication and session management to prevent recurrence. 8. Maintain comprehensive logging and monitoring to detect suspicious authentication attempts or access anomalies for timely incident response.
