Explain it like I’m five

Even the admin tier is not a safety net here: input from a privileged account can cross from configuration into code execution.

SIMPLIFIED_ATTACK_PATH03 STEPS
  1. 01Privileged access

    An attacker with high AEM privileges reaches the vulnerable function.

  2. 02Input accepted unchecked

    The attacker submits input AEM does not properly validate.

  3. 03Code executes

    The attacker's input runs in the application's context.

What happened

Adobe disclosed CVE-2026-106626 in bulletin APSB26-152: an improper input validation vulnerability (CWE-20) in Adobe Experience Manager that could result in arbitrary code execution for a highly privileged attacker.

Adobe’s bulletin APSB26-152 covers Experience Manager 6.5 release lines and their hotfixes. Apply the hotfix Adobe lists for your exact 6.5 version rather than assuming one package fits all.

What to do

  1. Inventory every Adobe Experience Manager deployment, including test, training, and individually managed instances.
  2. Apply the vendor fix or upgrade exactly as directed in the linked vendor bulletin or advisory.
  3. Restrict network access to Adobe Experience Manager while remediation is underway, especially for internet-facing instances.
  4. Review application and server logs for privileged-account actions outside change windows and new packages, users, or replication agents.
  5. Check for accounts, content, or configuration created outside normal change processes, and rotate exposed credentials where access cannot be ruled out.
  6. Verify the deployed version or patch level after remediation.

Management note

The privilege requirement narrows the threat to insiders and stolen admin credentials, which are exactly the accounts worth auditing after you hotfix.
