CVE-2025-54247 is a medium-severity vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.23.0 and earlier. The root cause is improper input validation (CWE-20), which allows a low-privileged attacker to bypass security features and gain unauthorized read access to protected resources. Specifically, the vulnerability enables an attacker without high privileges and without user interaction to circumvent access controls, potentially exposing sensitive information. The CVSS v3.1 score is 6.5, reflecting a network attack vector (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N, A:N). Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk because it compromises confidentiality by allowing unauthorized data disclosure. The lack of patches at the time of reporting increases the urgency for organizations to monitor for updates and apply mitigations. Adobe Experience Manager is widely used by enterprises for content management and digital experience delivery, making this vulnerability particularly relevant for organizations relying on AEM for web content and digital asset management.

For European organizations, the impact of CVE-2025-54247 could be substantial, especially for those in sectors such as government, finance, healthcare, and media that rely heavily on Adobe Experience Manager for managing sensitive content and customer data. Unauthorized read access could lead to exposure of confidential business information, personal data protected under GDPR, intellectual property, and other sensitive materials. This exposure risks regulatory penalties, reputational damage, and potential secondary attacks leveraging leaked information. Since the vulnerability requires only low privileges and no user interaction, it lowers the barrier for attackers to exploit it remotely over the network. The confidentiality breach could also facilitate espionage or competitive intelligence gathering. Given the critical role of AEM in digital experience platforms, disruption or data leakage could affect customer trust and operational continuity.

European organizations should implement the following specific mitigation steps: 1) Immediately inventory all Adobe Experience Manager instances and confirm versions; prioritize upgrading to versions later than 6.5.23.0 once Adobe releases a patch. 2) Until patches are available, restrict network access to AEM instances by implementing strict firewall rules and network segmentation to limit exposure to trusted internal users only. 3) Employ web application firewalls (WAFs) with custom rules to detect and block anomalous input patterns that could exploit input validation flaws. 4) Conduct thorough access reviews to minimize privileges assigned to users and service accounts interacting with AEM, reducing the attack surface. 5) Monitor logs and network traffic for unusual read access patterns or unauthorized data retrieval attempts. 6) Engage with Adobe security advisories and subscribe to threat intelligence feeds to receive timely updates on patches and exploit developments. 7) Consider deploying runtime application self-protection (RASP) solutions that can detect and block exploitation attempts in real time. These targeted mitigations go beyond generic advice by focusing on access control tightening, network isolation, and proactive detection tailored to the nature of this vulnerability.
