Adobe Experience Manager EUVD-2026-100530

Exploitation requires the attacker to already hold a HIGH-privilege account (PR:H) on the target Adobe Experience Manager instance - such as an administrator or author-level user - which is the primary limiting factor; this is not exploitable by anonymous/unauthenticated remote users. No user interaction is required (UI:N) and the attack is network-reachable (AV:N) against the affected AEM component once privileged access is held. Affected deployments are AEM as a Cloud Service ≤2026.9.28187, AEM 6.5 ≤6.5.25, and AEM 6.5 LTS ≤6.5 LTS SP3; instances already patched to versions above these ranges are not exploitable. The changed scope (S:C) means successful code execution may impact resources beyond the vulnerable component.

This is a genuine high-priority issue for organizations running Adobe Experience Manager, but its real-world risk is tempered by a meaningful precondition. The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H, 9.1 Critical) indicates a network-reachable, low-complexity attack requiring no user interaction, with full confidentiality, integrity and availability impact and a changed scope - reflecting that code execution can affect resources beyond the vulnerable component. The critical caveat is PR:H: successful exploitation requires an attacker who already holds HIGH privileges (e.g., an administrative/author account) on the AEM instance, so this is not a remote-unauthenticated path despite the 9.1 score. No EPSS probability was supplied in the input, there is no CISA KEV listing, and no public proof-of-concept is referenced - so there is no public exploit identified at time of analysis. The signals are therefore internally consistent: a severe technical impact (RCE) gated behind privileged access, reported responsibly by Adobe PSIRT rather than discovered in active exploitation. Net: prioritize patching for internet-exposed or multi-tenant AEM author instances where privileged accounts are numerous or federated, but this is lower urgency than a comparable unauthenticated RCE. Note the apparent tension between the 9.1 'Critical' rating and the PR:H requirement - teams should weight the privilege prerequisite heavily when triaging.

An attacker who has obtained a high-privilege (administrator/author) account on an Adobe Experience Manager instance - via credential theft, insider access, or a chained lower-privilege flaw - submits crafted input to an affected AEM component that fails proper input validation. Because no user interaction is needed and the scope is changed, the malicious input is processed into arbitrary code execution in the context of the current user, potentially reaching resources beyond the originally vulnerable component. No public proof-of-concept exploit is currently identified.
