⚠️ Patch immediately. CISA added this to its Known Exploited Vulnerabilities catalog on October 15, 2025 with a remediation deadline of November 5, 2025. Public exploitation is happening.

What is CVE-2025-54253?

Adobe Experience Manager Forms has a misconfiguration in how it enforces authorization checks. The flaw lets an attacker bypass the security model and execute arbitrary code on the AEM Forms server. Because AEM Forms is typically deployed as a customer-facing application server handling enterprise forms, PDF rendering, and document workflows, code execution here usually means full server compromise with access to the document data store.

The CWE-863 classification (Incorrect Authorization) is the technical root cause: AEM Forms grants access where it shouldn't, and that pathway leads straight to RCE.

Am I affected?

Per Adobe's APSB25-82 advisory, this vulnerability hits Adobe Experience Manager Forms versions 6.5.23 and earlier on all supported platforms (Windows, Linux, AIX, Solaris).

To check your installed AEM version:

  1. Log into the AEM author or publish instance.
  2. Open Tools → Operations → System Information, or browse to http://<your-aem-host>:<port>/system/console/status-productinfo.
  3. Look for the line Adobe Experience Manager, 6.5.x.x.SP. If the patch level is 6.5.23 or lower, you're affected.

You can also check from the OS:


# Linux/Unix
ls -la /path/to/aem/crx-quickstart/cq-quickstart-*.jar

# Windows
dir C:\AEM\crx-quickstart\cq-quickstart-*.jar

The filename includes the version (e.g. cq-quickstart-6.5.0.jar plus the cumulative service pack jar).

How to fix CVE-2025-54253

  1. Download AEM Forms 6.5 Service Pack 24 (or the latest cumulative fix pack) from the Adobe Software Distribution portal: experienceleague.adobe.com/docs/experience-manager-release-information/aem-release-updates.html. You need an authorized Adobe account.
  2. Back up your AEM repository. From the operations dashboard, run an online or offline backup of the crx-quickstart/repository directory. Do not skip this, service pack installs touch OSGi bundles and JCR nodes.
  3. Stop the AEM instance cleanly using the appliance scripts (./crx-quickstart/bin/stop on Linux or crx-quickstart\bin\stop.bat on Windows). Wait for all OSGi bundles to deregister.
  4. Install the service pack package via the AEM Package Manager once you restart in maintenance mode, or place the cumulative fix pack jar in crx-quickstart/install/ for automatic deployment on next start.
  5. Restart AEM and watch error.log for any bundle activation failures. Re-run any custom code activations that the service pack invalidated.
  6. Repeat on each environment: author tier, publish tier, dispatcher hosts (if any custom logic lives there), and DR replicas. Do not run a mixed-version cluster in production for longer than the migration window requires.

For AEM as a Cloud Service customers, Adobe applies these patches automatically, verify by checking the service version banner in the Cloud Manager console.

Patch via your OS package manager


# The exact package name and patched version are listed in the vendor advisory:
# https://helpx.adobe.com/security/products/aem-forms/apsb25-82.html
# Debian / Ubuntu
sudo apt update
sudo apt install --only-upgrade adobeexperiencemanager

# RHEL / Rocky / AlmaLinux / Fedora
sudo dnf upgrade adobeexperiencemanager

# openSUSE
sudo zypper update adobeexperiencemanager

# Verify the running version matches the fixed version
dpkg -s adobeexperiencemanager 2>/dev/null | grep -i version || rpm -q adobeexperiencemanager 2>/dev/null


# Windows: pull the cumulative update that ships this fix.
Install-Module PSWindowsUpdate -Force -SkipPublisherCheck
Get-WindowsUpdate -AcceptAll -Install -AutoReboot

Verify the fix landed


# 1. Confirm the running version matches the fixed-in version from the advisory:
#    https://helpx.adobe.com/security/products/aem-forms/apsb25-82.html
#    Use the platform-specific version probe above.

# 2. Re-scan with your vulnerability scanner (Nessus, Qualys, Tenable, OpenVAS).
#    The scanner should no longer flag CVE-2025-54253 on the patched target.

# 3. Inspect recent service / kernel logs for crash loops or rollback events.
journalctl -u <service> --since "10 minutes ago"
dmesg --since "10 minutes ago"

If you can't patch immediately

The Adobe advisory APSB25-82 does not list a workaround. The only documented remediation is to update to the patched service pack. If you absolutely cannot patch in the federal-deadline window, take these emergency steps:

None of these stop the vulnerability, they just reduce the exposure surface while you finish the patch.

How to verify the fix worked

After the service pack installs and AEM restarts, confirm the version:

  1. Browse to http://<your-aem-host>:<port>/system/console/status-productinfo (basic auth as admin).
  2. The product info should now show Adobe Experience Manager 6.5.24 or higher.
  3. In the OSGi console at /system/console/bundles, verify the com.adobe.forms.* bundles are in the Active state with the new version numbers.

Re-run your authenticated vulnerability scan against the AEM management endpoint. The CVE-2025-54253 finding should clear.

Frequently asked questions

Other vulnerabilities in the same area that are worth patching alongside this one:

Is CVE-2025-54253 being exploited in the wild?

Yes. CISA added it to the KEV catalog on October 15, 2025, which is CISA's standard signal for confirmed in-the-wild exploitation.

Does this affect AEM Sites or AEM Assets specifically?

The advisory scopes the fix to AEM Forms. AEM Sites and AEM Assets share the same underlying CQ platform, so applying the cumulative service pack updates all modules together. Customers running AEM without the Forms add-on still get the security fix as part of SP24.

What about AEM 6.4 and earlier?

AEM 6.4 reached end of extended support in April 2023. Adobe does not publish security fixes for it. The remediation path is to migrate to AEM 6.5 SP24 or AEM as a Cloud Service.
