- Note: The CVE record and the advisory differ on details; see the advisory for on-premise fixes.
Fixed in
- AEM Cloud Service: 2026.10.29251
- AEM 6.5 and 6.5 LTS: Cumulative Hotfix for GRANITE-75052 or the applicable add-on (exact hotfix ID differs between the CVE record and the advisory; check APSB26-189 for each installation)
- AEM 6.5 with Forms Add-On: AEM Forms 6.5 SP25 Add-on
- AEM 6.5 without Forms Add-On: Forms Hotfix for AEM 6.5 QuickStart 1.0.12
- AEM 6.5 LTS without Forms Add-On: Not affected according to the advisory
Workaround
- Unknown. No workaround was found for unpatched systems.
Exploitation
- Adobe is not aware of any exploits in the wild for the issues in this update.
- The CVE is not listed in the CISA KEV catalogue.
- No public proof of concept was found; this does not rule one out.
Our recommendation
- Confirm that AEM Cloud Service runs version 2026.10.29251 or later.
- For on-premise AEM 6.5 or 6.5 LTS, identify the exact hotfix or add-on for your installation in APSB26-189 and apply it.
- Prioritise the critical issues in the same bulletin, as they carry higher risk.
- Warn users not to open untrusted links and monitor for suspicious browser activity.
