The Cybersecurity and Infrastructure Security Agency (CISA) has issued an urgent alert concerning a critical vulnerability in Adobe Experience Manager (AEM) Forms, identified as CVE-2025-54253. This flaw, affecting the Java Enterprise Edition (JEE) version of AEM Forms, allows attackers to execute arbitrary code on unpatched systems. Given its severity and active exploitation, organizations are strongly advised to apply the necessary patches without delay.
Understanding CVE-2025-54253
CVE-2025-54253 is a misconfiguration vulnerability that has been assigned a Common Vulnerability Scoring System (CVSS) score of 9.8 out of 10, indicating its critical nature. The flaw is particularly dangerous because it requires neither user interaction nor authentication to be exploited. Attackers can leverage this vulnerability to gain full control over affected servers, potentially leading to data theft, deployment of ransomware, or further network compromise.
