CVE-2026-61264: Oracle Call Center Tech Auth Bypass Flaw

CVE-2026-61264 Overview

CVE-2026-61264 is an improper access control vulnerability [CWE-284] in the Oracle Call Center Technology product of Oracle E-Business Suite. The flaw resides in the RDBMS and UI components and affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit this vulnerability to compromise Oracle Call Center Technology. Successful exploitation allows unauthorized update, insert, or delete access to a portion of Oracle Call Center Technology data, plus unauthorized read access to a subset of data. Oracle addressed the issue in the July 2026 Critical Patch Update.

Critical Impact
Authenticated attackers can modify and read Oracle Call Center Technology data over the network, impacting the confidentiality and integrity of call center records.

Technical Details for CVE-2026-61264

Vulnerability Analysis

The vulnerability is classified under [CWE-284] Improper Access Control. Oracle Call Center Technology fails to enforce proper authorization checks across its RDBMS and UI components. An authenticated user with low privileges can send crafted HTTP requests to reach data operations outside their intended permission scope.

The issue impacts both confidentiality and integrity. Attackers can read a subset of accessible data and can perform unauthorized INSERT, UPDATE, or DELETE operations against records the application exposes. Availability is not affected. The vulnerability requires no user interaction and can be exploited remotely across a network path.

Oracle Call Center Technology handles customer interaction records, agent activity, and campaign data. Unauthorized modification of these records can corrupt customer service workflows and compromise the accuracy of call center reporting.

Root Cause

The root cause is missing or insufficient authorization enforcement between the UI layer and the underlying RDBMS operations. Access control decisions rely on privileges that do not adequately restrict low-privileged accounts from reaching sensitive data pathways. Refer to the Oracle Security Alert July 2026 for vendor-supplied technical context.

Attack Vector

Exploitation requires network access via HTTP and valid low-privileged credentials to the Oracle E-Business Suite environment. The attacker sends crafted requests to Oracle Call Center Technology endpoints. The application processes the requests without applying full authorization checks, allowing the attacker to reach unintended data operations. No user interaction is required.

Detection Methods for CVE-2026-61264

Indicators of Compromise

Unexpected INSERT, UPDATE, or DELETE operations against Call Center Technology tables originating from low-privileged user sessions.
HTTP requests to Oracle E-Business Suite Call Center Technology endpoints from accounts that do not typically use these functions.
Database audit entries showing data access outside a user's assigned responsibility set.

Detection Strategies

Enable Oracle E-Business Suite audit logging and Oracle Database Fine-Grained Auditing on Call Center Technology tables.
Review web tier access logs for unusual URL patterns targeting Call Center Technology modules.
Correlate database change events with authenticated web session identifiers to detect privilege mismatches.

Monitoring Recommendations

Baseline normal call center agent activity and alert on deviations in record modification volume or timing.
Forward Oracle E-Business Suite application, middle-tier, and database audit logs to a centralized SIEM for correlation.
Track failed and successful authorization checks on Call Center Technology responsibilities and menus.

How to Mitigate CVE-2026-61264

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all affected Oracle E-Business Suite 12.2.3 through 12.2.15 environments.
Inventory Oracle Call Center Technology accounts and remove or restrict low-privileged accounts that no longer require access.
Review recent database audit records for signs of unauthorized data modification prior to patching.

Patch Information

Oracle released the fix as part of the July 2026 Critical Patch Update. Refer to the Oracle Security Alert July 2026 for patch identifiers, installation prerequisites, and post-patch validation steps. Apply patches in a test environment before production rollout.

Workarounds

Restrict network access to Oracle E-Business Suite HTTP endpoints using perimeter controls and VPN enforcement until patches are applied.
Reduce the assignment of Call Center Technology responsibilities to the minimum set of users required.
Enable enhanced database auditing on Call Center Technology schemas to detect exploitation attempts.

bash

# Enable Fine-Grained Auditing on a Call Center Technology table (example)
BEGIN
  DBMS_FGA.ADD_POLICY(
    object_schema   => 'APPS',
    object_name     => '<CCT_TABLE_NAME>',
    policy_name     => 'CCT_ACCESS_AUDIT',
    statement_types => 'SELECT,INSERT,UPDATE,DELETE'
