CVE-2026-60630: Oracle APEX Auth Bypass Vulnerability

CVE-2026-60630 Overview

CVE-2026-60630 is a local information disclosure vulnerability in Oracle Application Express (APEX) affecting the Installation component. Supported versions 24.1, 24.2, and 26.1 are affected. A low-privileged attacker with logon access to the infrastructure where Oracle APEX executes can exploit this weakness to gain unauthorized access to critical data. Oracle disclosed the flaw in its July 2026 Critical Patch Update.

Critical Impact
Successful exploitation results in unauthorized access to all Oracle APEX accessible data, compromising confidentiality of application data managed by the platform.

Affected Products

Oracle APEX 24.1
Oracle APEX 24.2
Oracle APEX 26.1

Technical Details for CVE-2026-60630

Vulnerability Analysis

The vulnerability resides in the Installation component of Oracle APEX, Oracle's low-code development platform for building enterprise web applications. Attackers require local logon access to the infrastructure where Oracle APEX executes and only low privileges to exploit the issue. No user interaction is required.

Exploitation impacts confidentiality only. Integrity and availability of the system remain unaffected. The scope is unchanged, meaning the compromise stays within the vulnerable component's security authority.

Because the flaw is present in the Installation component, it likely involves exposure of sensitive configuration, credentials, or metadata generated or referenced during APEX setup. Successful attacks yield access to critical data or complete access to all APEX-accessible data.

EPSS data indicates a low probability of near-term exploitation. No public proof-of-concept, exploit code, or evidence of exploitation in the wild has been reported. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Root Cause

Oracle has not published detailed root-cause information. The Installation component appears to expose sensitive data to authenticated local users who should not have access to it. This aligns with an information exposure weakness class.

Attack Vector

Attack requires local access with valid credentials on the infrastructure hosting Oracle APEX. The attacker leverages that foothold to read data belonging to other APEX tenants, workspaces, or the platform itself. Remote or unauthenticated exploitation is not possible.

Refer to the Oracle Security Alert July 2026 for vendor-provided technical details.

Detection Methods for CVE-2026-60630

Indicators of Compromise

Unexpected reads of APEX installation artifacts, configuration files, or metadata tables by non-administrative accounts.
Local logons to APEX infrastructure hosts by low-privileged accounts outside normal operational windows.
Anomalous access to APEX workspace credentials, schema mappings, or bootstrap files.

Detection Strategies

Audit local authentication events on servers running Oracle APEX and correlate with subsequent file and database access.
Enable database auditing on APEX metadata schemas (APEX_*) to record SELECT activity against sensitive tables.
Baseline expected access patterns for the Installation component and alert on deviations.

Monitoring Recommendations

Forward host, database, and application logs from APEX servers to a centralized analytics platform for correlation.
Monitor privileged and semi-privileged account activity on APEX infrastructure for lateral read attempts.
Track file integrity on APEX installation directories to detect unauthorized inspection or copying.

How to Mitigate CVE-2026-60630

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle APEX 24.1, 24.2, and 26.1 deployments.
Inventory all APEX instances, including development, test, and production, to ensure complete patch coverage.
Review and reduce the population of local accounts with logon rights to APEX infrastructure hosts.

Patch Information

Oracle addressed CVE-2026-60630 in the July 2026 Critical Patch Update. Administrators should review the Oracle Security Alert July 2026 for patch matrices and installation guidance specific to versions 24.1, 24.2, and 26.1.

Workarounds

Restrict interactive and remote logon to APEX servers to a minimal set of administrative identities until patches are applied.
Enforce least-privilege on file system and database objects associated with APEX installation artifacts.
Rotate credentials, API keys, and secrets referenced in APEX configuration if unauthorized local access is suspected.

bash

# Configuration example: restrict local logon and audit APEX metadata reads
# 1. Limit interactive logon on the APEX host (Linux example)
sudo usermod -s /sbin/nologin <low_priv_account>

# 2. Enable Oracle DB auditing on APEX schemas
sqlplus / as sysdba <<EOF
AUDIT SELECT ON APEX_240200.WWV_FLOW_INSTALL BY ACCESS;
AUDIT SELECT ON APEX_240200.WWV_FLOW_PLATFORM_PREFS BY ACCESS;
