Urgent Alert: Adobe AEM Forms 0-Day Vulnerabilities Expose Organizations to Arbitrary Code Execution Risks

Organizations leveraging Adobe Experience Manager (AEM) Forms on Java Enterprise Edition (JEE) face an immediate and severe security threat. Adobe has issued an urgent security update to patch two critical zero-day vulnerabilities that could enable attackers to execute arbitrary code and gain unauthorized access to file systems. This development underscores the persistent and evolving nature of cyber threats, demanding swift and decisive action from IT and security teams.

Understanding the Critical Zero-Day Vulnerabilities

The vulnerabilities, identified as CVE-2025-54253 and CVE-2025-54254, have been assigned Adobe’s highest priority rating. This classification is a direct reflection of their potential impact and the confirmed existence of proof-of-concept (PoC) exploits in the wild. The designation of “zero-day” signifies that these flaws were unknown to Adobe and unpatched until very recently, leaving a window of opportunity for malicious actors to exploit them before a fix was available.

• CVE-2025-54253: Arbitrary Code Execution – This vulnerability permits an unauthenticated attacker to execute arbitrary code on the affected AEM Forms server. This level of access grants adversaries significant control, potentially leading to data exfiltration, system compromise, or the installation of further malicious software.
• CVE-2025-54254: Unauthorized File System Access – Complementing the arbitrary code execution, this flaw allows attackers to gain unauthorized access to the underlying file system. Such access can lead to the theft of sensitive data, modification of critical system files, or even denial-of-service conditions.

Implications for Organizations

The combination of arbitrary code execution and unauthorized file system access creates a severe risk posture for organizations. Compromised AEM Forms instances could become launchpads for broader network attacks, giving threat actors a persistent foothold within an enterprise environment. Given the widespread use of Adobe AEM Forms for critical business processes, including data collection and document management, the potential for disruption and data breaches is extremely high.

Remediation Actions: Immediate Steps Required

Adobe’s urgent security update is paramount for mitigating these critical vulnerabilities. Organizations must prioritize the immediate application of the relevant patches to secure their AEM Forms deployments.

• Patch Immediately: Identify all instances of Adobe Experience Manager Forms on Java Enterprise Edition (JEE) within your infrastructure. Apply the latest security updates released by Adobe without delay.
• Verify Patch Application: After applying the patches, thoroughly verify their successful installation and ensure that the vulnerabilities are no longer exploitable.
• Network Segmentation: If not already in place, implement or strengthen network segmentation to limit the blast radius in case of a compromise. Isolate AEM Forms environments from other critical systems.
• Monitor Logs: Increase monitoring of AEM Forms server logs for any suspicious activity, unauthorized access attempts, or unusual process executions.
• Regular Backups: Ensure up-to-date and secure backups of all AEM Forms data and configurations.
