CVE-2026-60777: Oracle E-Business Suite Auth Bypass Flaw

CVE-2026-60777 Overview

CVE-2026-60777 is a vulnerability in the Oracle Application Object Library, a core component of Oracle E-Business Suite. The flaw affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit the weakness without user interaction. Successful exploitation allows unauthorized update, insert, or delete operations against a subset of accessible data. Attackers can also gain unauthorized read access to some data and trigger a partial denial of service against the Application Object Library.

Critical Impact
Authenticated network-based attackers can modify and read data within the Oracle Application Object Library and cause partial service disruption in affected E-Business Suite deployments.

Affected Products

Oracle E-Business Suite - Oracle Application Object Library version 12.2.3
Oracle E-Business Suite - Oracle Application Object Library versions 12.2.4 through 12.2.14
Oracle E-Business Suite - Oracle Application Object Library version 12.2.15

Technical Details for CVE-2026-60777

Vulnerability Analysis

The vulnerability resides in the Core component of the Oracle Application Object Library (AOL), the foundational technology layer that underpins Oracle E-Business Suite modules. AOL provides shared services such as concurrent processing, flexfields, forms, and user session handling across E-Business Suite applications. A weakness in this component exposes data managed by AOL to tampering by any user who can authenticate to the application server over HTTP.

The attack surface is reachable across the network without requiring adjacent access. The scope of exploitation is limited to resources managed by the vulnerable component itself, so a compromise does not automatically translate into full-system access. Impact spans confidentiality, integrity, and availability at a partial level, with integrity being the most notable outcome given the write capability attackers gain.

Root Cause

Oracle has not published detailed technical information beyond the July 2026 Critical Patch Update. Based on the advisory metadata, the flaw stems from insufficient enforcement of access controls on operations exposed by the Application Object Library over HTTP. Low-privileged authenticated users can invoke functionality that should be restricted, resulting in unauthorized read and write operations.

Attack Vector

Exploitation requires network access to the Oracle E-Business Suite HTTP interface and valid low-privileged credentials. No user interaction is needed. After authenticating, an attacker sends crafted requests to AOL endpoints to trigger the vulnerable code path. The attack complexity is low, meaning specialized conditions or timing are not required for reliable exploitation.

No public proof-of-concept code, exploit script, or CISA KEV listing exists for CVE-2026-60777 at the time of publication. The EPSS probability is 0.272% (percentile 19.233), indicating no observed exploitation activity yet. Refer to the Oracle Security Alert - July 2026 for authoritative technical details.

Detection Methods for CVE-2026-60777

Indicators of Compromise

Unexpected INSERT, UPDATE, or DELETE operations executed by low-privileged E-Business Suite accounts against AOL-owned tables such as FND_USER, FND_RESPONSIBILITY, or profile option tables.
HTTP requests to AOL servlets and JSPs originating from user sessions with no legitimate business need to access those endpoints.
Anomalous concurrent request submissions or profile changes recorded in FND_LOG_MESSAGES outside standard change windows.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and page access tracking to identify low-privileged accounts touching AOL administrative surfaces.
Correlate web tier access logs (access_log from Oracle HTTP Server) with application audit records to detect abnormal request volumes or response patterns.
Baseline normal user activity for each responsibility and alert on deviations, particularly write operations against foundation tables.

Monitoring Recommendations

Forward Oracle HTTP Server, WebLogic, and E-Business Suite audit logs into a centralized SIEM for correlation and long-term retention.
Monitor database-layer auditing for direct changes to AOL schema objects performed through application connection pools.
Track failed and successful authentication attempts against E-Business Suite to detect credential stuffing that could precede exploitation.

How to Mitigate CVE-2026-60777

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite environments running versions 12.2.3 through 12.2.15.
Inventory all internet-facing and internal E-Business Suite instances and confirm patch status against the Oracle advisory.
Rotate credentials for any low-privileged accounts that showed anomalous activity prior to patching.

Patch Information

Oracle addressed CVE-2026-60777 in the July 2026 Critical Patch Update. Administrators should download and apply the relevant patch for Oracle Application Object Library as documented in the Oracle Security Alert - July 2026. Test the patch in a staging environment, then roll out to production following Oracle's recommended application steps for E-Business Suite 12.2.

Workarounds

Restrict network access to the E-Business Suite HTTP tier using firewalls, VPN, or reverse proxies until patching is complete.
Enforce least privilege by reviewing responsibilities assigned to standard users and removing unnecessary AOL-related privileges.
Enable multi-factor authentication for all E-Business Suite accounts to raise the cost of credential-based access.
Increase audit and monitoring coverage on AOL endpoints during the remediation window.
