A security feature bypass vulnerability in Adobe Experience Manager allows low-privileged attackers to gain unauthorized read access to sensitive data.

This is an improper input validation vulnerability (CWE-20) that allows a low-privileged, authenticated attacker to bypass established security controls via network-based exploitation.

The ability for a low-privileged user to bypass security features and access unauthorized data poses a significant risk to organizational confidentiality. Given the CVSS score of 7.7, this is classified as a High severity issue that could lead to the exposure of sensitive proprietary or customer information. System administrators should prioritize this update to prevent potential data exfiltration and maintain the integrity of their security posture.

Immediate Action: Update Adobe Experience Manager to the latest version provided by the vendor in the official security bulletin APSB25-90.

Proactive Monitoring: Review application access logs for unusual patterns of authorization failures or attempts to access restricted endpoints by low-privileged user accounts.

Compensating Controls: Implement strict network segmentation and ensure that Web Application Firewalls are configured to inspect incoming requests for anomalous input patterns that may attempt to trigger input validation failures.

Public Exploit Available: Unknown

This vulnerability represents a significant risk to the confidentiality of data stored within Adobe Experience Manager environments. Organizations should treat this as a high-priority update task, ensuring that all instances are patched to the version specified by Adobe to eliminate the security feature bypass risk. Regular audit of user privileges is also recommended to limit the potential impact of such vulnerabilities.
