Summary

CVE-2026-48252 is a Missing Authentication for Critical Function vulnerability (CWE-306) in Adobe Experience Manager (AEM) affecting AEM as a Cloud Service, AEM 6.5 LTS, and AEM 6.5. Rated High severity with a CVSS v3.1 base score of 8.6, the flaw allows unauthenticated remote attackers to bypass security controls and gain unauthorized write access to the system, with scope changed beyond the vulnerable component.

Technical details

  • Root cause: A critical server-side function lacks proper authentication enforcement (CWE-306 – Missing Authentication for Critical Function), allowing requests to reach privileged functionality without any credential check.
  • Trigger conditions: No authentication, no user interaction, and low attack complexity are required — any unauthenticated attacker reachable over the network can attempt exploitation.
  • Attack vector: Network-based (AV:N); AEM instances are internet-exposed by design, serving public-facing web content for enterprises, making them directly reachable.
  • Impact: Successful exploitation results in unauthorized write access with changed scope (S:C, I:H). In the context of AEM — which manages enterprise web content, digital assets, and publishing workflows — this could enable content defacement, injection of malicious content, data manipulation, or serve as a foothold for further compromise. Confidentiality and availability are not directly impacted by this vector.

Affected software

  • Adobe Experience Manager as a Cloud Service – Release 2026.5.0 and earlier
  • Adobe Experience Manager 6.5 LTS – Service Pack 1 and earlier
  • Adobe Experience Manager 6.5 – 6.5.24 and earlier

Severity

  • CVSS v3.1 Base Score: 8.6 (High)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N

Mitigation and recommended actions

  • AEM as a Cloud Service: Update to Release 2026.6.0 — Adobe deploys this automatically to Cloud Service customers; verify your environment has received the update.
  • AEM 6.5 LTS: Apply Service Pack 2 (includes hotfix NPR-43972).
  • AEM 6.5: Apply Service Pack 25 (includes hotfix NPR-43971).
  • If immediate patching is not possible, restrict network-level access to AEM authoring and administrative endpoints using web application firewall (WAF) rules or perimeter controls to limit exposure to trusted networks only.
  • Adobe has reported no known exploits in the wild at time of publication; however, given the unauthenticated nature of the vulnerability and AEM’s broad internet exposure, prompt patching is strongly recommended.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
