Insufficient Session Expiration in Adobe ColdFusion

Executive Summary

CVE-2026-48329 is an Insufficient Session Expiration vulnerability in Adobe ColdFusion. This flaw allows a high-privileged attacker to bypass security measures and gain unauthorized write access to the system.

The vulnerability does not require any user interaction to be exploited. This means an attacker with elevated privileges can leverage it without needing actions from other users.

The CVSS v3.1 score for this vulnerability is 2.7, categorized as low severity. The vector is AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N, indicating it is exploitable over a network with low attack complexity, requires high privileges, and has no impact on confidentiality or availability but allows low integrity impact.

Compliance Impact

This vulnerability could impact compliance with several standards and regulations, depending on the context of your organization.

• GDPR: If the unauthorized write access leads to the alteration or exposure of personal data, it could violate GDPR requirements for data integrity and confidentiality. Organizations may face penalties for failing to protect personal data adequately.
• HIPAA: For organizations handling protected health information (PHI), this vulnerability could result in unauthorized modifications to PHI, violating HIPAA's integrity and security rules. This could lead to non-compliance and potential fines.
• Other standards: Compliance frameworks like ISO 27001, NIST, or PCI DSS require robust access controls and session management. This vulnerability could indicate a failure to meet these requirements, leading to compliance gaps.

Organizations should assess the potential impact of this vulnerability on their compliance posture and take corrective actions to mitigate risks.

Mitigation Strategies

• Apply the latest security patches or updates provided by Adobe for ColdFusion, as they may address this vulnerability.
• Review and enforce strict session expiration policies to ensure sessions are invalidated promptly after use or inactivity.
• Restrict high-privileged access to ColdFusion administrative interfaces to minimize the risk of exploitation.
• Monitor logs for unusual session activity or unauthorized write operations that could indicate exploitation attempts.
• Consider implementing additional security controls, such as network segmentation or intrusion detection systems, to detect and prevent unauthorized access.
