CVE-2026-61110 Overview
CVE-2026-61110 is a high-severity vulnerability in the Oracle Applications DBA product of Oracle E-Business Suite, specifically in the ADPatch component. Supported versions 12.2.3 through 12.2.15 are affected. The flaw allows a low-privileged attacker with network access via HTTP to compromise Oracle Applications DBA. Successful exploitation results in full takeover of the Oracle Applications DBA, impacting confidentiality, integrity, and availability. Oracle disclosed the issue in the Oracle Security Alert July 2026.
Critical Impact
Authenticated attackers can achieve complete takeover of Oracle Applications DBA over the network with low complexity and no user interaction.

Technical Details for CVE-2026-61110
Vulnerability Analysis
The vulnerability resides in the ADPatch component of Oracle Applications DBA, part of the Oracle E-Business Suite platform. ADPatch is the patching utility responsible for applying Oracle E-Business Suite updates and managing database administration tasks. An attacker with low-privileged credentials can send crafted requests over HTTP to reach the vulnerable functionality. Successful exploitation results in a scope-unchanged compromise with high impact to confidentiality, integrity, and availability. Because ADPatch operates with elevated privileges over the E-Business Suite environment, a takeover exposes application configurations, database contents, and administrative operations.
Root Cause
Oracle has not published the specific technical root cause in the public advisory. The Oracle Security Alert July 2026 describes the issue as an exploitable weakness in ADPatch reachable through the HTTP interface exposed by Oracle Applications DBA. Consult the Oracle Security Alert July 2026 for vendor-authoritative details.
Attack Vector
The attack vector is network-based over HTTP. The attacker must hold low-level privileges within the Oracle E-Business Suite environment but does not require user interaction. Attack complexity is low, and the scope is unchanged. Once exploited, the attacker controls the Oracle Applications DBA context, enabling arbitrary administrative actions across the E-Business Suite stack.
No verified proof-of-concept code has been published for CVE-2026-61110. Refer to the vendor advisory for authoritative technical details.
Detection Methods for CVE-2026-61110
Indicators of Compromise
- Unexpected ADPatch sessions initiated from low-privileged accounts or unusual source IP addresses.
- HTTP requests targeting Oracle Applications DBA endpoints outside normal patching windows.
- Unauthorized changes to Oracle E-Business Suite configuration files, patch history, or AD_* tables.
- New administrative database accounts or role grants originating from the applmgr or DBA context.
Detection Strategies
- Monitor Oracle E-Business Suite application server logs for anomalous invocations of ADPatch and related adop utilities.
- Review web-tier access logs for authenticated HTTP requests to Oracle Applications DBA URIs from non-administrative users.
- Correlate database audit logs with application-layer authentication events to identify privilege escalation patterns.
Monitoring Recommendations
- Enable Oracle Database Fine-Grained Auditing on APPLSYS and AD schemas to capture privileged operations.
- Alert on modifications to $APPL_TOP directories, patch inventories, and adop session tables.
- Track outbound connections from the E-Business Suite middle tier for signs of post-exploitation activity.
How to Mitigate CVE-2026-61110
Immediate Actions Required
- Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite deployments running versions 12.2.3 through 12.2.15.
- Restrict network access to Oracle Applications DBA HTTP endpoints to trusted administrative networks only.
- Audit and reduce the number of low-privileged accounts that hold access to E-Business Suite application interfaces.
- Rotate credentials for any accounts that may have interacted with ADPatch prior to patching.
Patch Information
Oracle addressed CVE-2026-61110 in the July 2026 Critical Patch Update. Administrators should review the Oracle Security Alert July 2026 for patch identifiers, prerequisite steps, and post-installation validation procedures specific to Oracle E-Business Suite 12.2.x.
Workarounds
- Place Oracle E-Business Suite web tiers behind a reverse proxy or WAF that enforces strict authentication for ADPatch-related URIs.
- Disable or firewall off HTTP access to Oracle Applications DBA components until the vendor patch is applied.
- Enforce least privilege by removing unnecessary responsibilities and application roles from non-administrative users.
# Example: restrict HTTP access to Oracle Applications DBA endpoints via iptables
iptables -A INPUT -p tcp --dport 8000 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -j DROP
