CVE-2025-26961

Remediation / Mitigation Strategy: CVE-2025-26961 - Missing Authorization in NotFound Fresh Framework

Vulnerability Description:

  • Vulnerability: Missing Authorization
  • Component: NotFound Fresh Framework
  • Affected Versions: Versions up to and including 1.70.0
  • Description: The NotFound Fresh Framework suffers from a Missing Authorization vulnerability. This means that certain functionalities within the framework are not properly protected by Access Control Lists (ACLs). This allows attackers to access features or data that they are not authorized to access.

Severity:

  • CVSS Score: 8.6 (High) - based on the provided data.
  • Impact: A high CVSS score indicates that this vulnerability has the potential for significant impact. An attacker exploiting this vulnerability could gain unauthorized access to sensitive data, modify configurations, or perform actions within the application that they should not be able to. The specific impact depends on the functionality that is accessible without proper authorization.

Known Exploit:

  • Exploit Status: Based on the information provided, it’s not clear if a public exploit is currently available (“n8n_cve_twitter_processed” suggests the CVE was processed, potentially indicating discussions, but doesn’t guarantee a public exploit). However, the existence of the CVE itself implies that an exploit is possible, and attackers may attempt to reverse engineer the vulnerability to create an exploit.

Remediation/Mitigation Strategy:

The primary goal is to ensure that all functionalities within the NotFound Fresh Framework are properly protected by robust and enforced access controls.

  1. Immediate Action: Upgrade (If Possible):

    • The first and most effective solution is to upgrade the NotFound Fresh Framework to a version patched to address CVE-2025-26961. Check the vendor’s (Fresh Framework developer) website or update channels for security patches or newer versions of the framework.
    • Critical: If a patch is available, apply it immediately.

  2. Identify Affected Functionality:

    • Conduct a thorough code review to identify all functionalities within the NotFound Fresh Framework that rely on access control lists (ACLs).
    • Specifically focus on functions, endpoints, or data access points that handle sensitive information or critical operations.
    • Identify any points where authorization checks might be missing or insufficient. This is a critical step for understanding the scope of the vulnerability.

  3. Implement Proper Authorization Checks:

    • Principle of Least Privilege: Enforce the principle of least privilege throughout the framework. Users should only be granted the minimum necessary permissions to perform their required tasks.
    • Explicit Authorization: For each potentially vulnerable function or endpoint, add explicit authorization checks. These checks should:
      • Authenticate the user (verify their identity).
      • Authorize the user (determine if they have the required permissions).
      • Fail securely (e.g., return an error message) if the user is not authorized.
    • Centralized Authorization: Consider using a centralized authorization mechanism (e.g., an access control service or a dedicated authorization library) to simplify and standardize authorization checks across the framework. This makes it easier to manage and audit access controls.

  4. Input Validation:

    • Implement strict input validation for all user-supplied data. This can help prevent attackers from bypassing authorization checks by manipulating input values.

  5. Web Application Firewall (WAF) Rules (Mitigation):

    • As a temporary mitigation measure (until a patch can be applied or proper authorization checks implemented), configure a Web Application Firewall (WAF) to detect and block malicious requests that attempt to exploit the vulnerability. This is a defensive layer, not a replacement for fixing the underlying code.
    • Create custom WAF rules based on the expected attack patterns. This may require analyzing the vulnerable code to understand how an attacker might exploit the missing authorization. The effectiveness of WAF rules depends heavily on the specific characteristics of the vulnerability.

  6. Monitoring and Logging:

    • Enable detailed logging of all authentication and authorization attempts. Monitor these logs for suspicious activity that could indicate an exploitation attempt.
    • Set up alerts to notify security personnel of any unusual patterns.

  7. Penetration Testing and Security Audits:

    • Conduct regular penetration testing and security audits to identify and address vulnerabilities in the NotFound Fresh Framework and other components of the application.
    • These tests should specifically focus on authorization-related vulnerabilities.

  8. Code Review and Training:

    • Train developers on secure coding practices, including proper authorization techniques.
    • Implement code review processes to ensure that all code changes are reviewed for security vulnerabilities before being deployed to production.

  9. Stay Informed:

    • Monitor security advisories and vulnerability databases for updates on CVE-2025-26961 and other vulnerabilities affecting the NotFound Fresh Framework and related technologies.

Important Considerations:

  • The exact steps required to remediate this vulnerability will depend on the specific implementation of the NotFound Fresh Framework and the functionality that is affected.
  • Thoroughly test all changes before deploying them to production.
  • Consult with security experts if you need assistance with remediation.
  • Document all remediation steps taken.
  • This response assumes a basic understanding of web application security concepts and best practices. If you need further explanation on any of the steps, please ask.
