CVE-2026-61296: Oracle E-Business Suite Auth Bypass Flaw

CVE-2026-61296 Overview

CVE-2026-61296 is a high-severity vulnerability in the Linear Asset Management component of Oracle Enterprise Asset Management, part of Oracle E-Business Suite. Affected versions span 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit this issue, though successful exploitation requires interaction from a user other than the attacker. The vulnerability carries a scope change, meaning attacks may impact components beyond Oracle Enterprise Asset Management itself. Successful exploitation can result in unauthorized access to all Oracle Enterprise Asset Management data and unauthorized modification of some data.

Critical Impact
Attackers can compromise confidentiality of all accessible data and modify a subset of application data, with cross-component impact due to scope change.

Affected Products

Oracle E-Business Suite — Oracle Enterprise Asset Management 12.2.3
Oracle E-Business Suite — Oracle Enterprise Asset Management versions 12.2.4 through 12.2.14
Oracle E-Business Suite — Oracle Enterprise Asset Management 12.2.15

Technical Details for CVE-2026-61296

Vulnerability Analysis

The vulnerability resides in the Linear Asset Management component of Oracle Enterprise Asset Management. It is remotely exploitable over HTTP and requires only low-level authenticated access to the application. Exploitation requires a victim user to perform an action, indicating a user-interaction-driven attack pattern such as clicking a crafted link or loading an attacker-influenced request in an authenticated session.

The scope change indicator signals that the vulnerable component and the impacted component differ. An attacker leveraging Oracle Enterprise Asset Management can affect resources managed by other Oracle E-Business Suite components. This behavior is characteristic of cross-component data exposure or client-side injection classes such as Cross-Site Scripting (XSS) or Cross-Site Request Forgery (CSRF) that pivot across trust boundaries in the E-Business Suite application stack.

Root Cause

Oracle has not published root-cause details in the public advisory. Based on the CVSS metrics (network vector, low privileges, required user interaction, scope change, high confidentiality impact, and low integrity impact), the flaw is consistent with insufficient validation or output encoding in a Linear Asset Management interface that a targeted user reaches through the browser. Refer to the Oracle Security Alert for authoritative technical details.

Attack Vector

An attacker authenticated to Oracle E-Business Suite with low privileges crafts a malicious HTTP request or link targeting the Linear Asset Management functionality. The attacker delivers the payload to a second, higher-privileged or differently-scoped user. When that user interacts with the payload from an authenticated session, the request executes in the victim's context. The scope change allows the attack to reach data or actions outside Oracle Enterprise Asset Management, expanding the blast radius across E-Business Suite modules.

No public proof-of-concept code is available for CVE-2026-61296 at the time of publication. See the vendor advisory for exploitation preconditions.

Detection Methods for CVE-2026-61296

Indicators of Compromise

Unexpected HTTP requests to Linear Asset Management endpoints under /OA_HTML/ originating from authenticated low-privileged accounts.
Session activity where a user's browser issues cross-module requests immediately after loading an externally-sourced link or email.
Audit records showing data reads or writes to Enterprise Asset Management objects that fall outside the normal role scope for the acting user.

Detection Strategies

Correlate Oracle E-Business Suite application logs with proxy and web server logs to identify unusual referrers preceding sensitive Linear Asset Management transactions.
Baseline the request patterns of low-privileged EAM users and alert on deviations, especially requests that trigger scope-crossing actions.
Inspect outbound email and messaging telemetry for URLs pointing at Oracle E-Business Suite hosts that include Linear Asset Management parameters.

Monitoring Recommendations

Enable and forward Oracle E-Business Suite FND audit logs and Apache access logs to a centralized analytics platform for retention and correlation.
Monitor authenticated sessions for concurrent activity from multiple source IP addresses, which may indicate a hijacked session driven by user interaction.
Track privileged account activity that follows immediately after any low-privileged user interaction with Linear Asset Management URLs.

How to Mitigate CVE-2026-61296

Immediate Actions Required

Apply the patches referenced in the Oracle Security Alert for August 2026 to all Oracle E-Business Suite environments running versions 12.2.3 through 12.2.15.
Inventory all Oracle E-Business Suite deployments and confirm whether Oracle Enterprise Asset Management with Linear Asset Management is enabled.
Restrict Oracle E-Business Suite network exposure so that only authenticated internal users can reach the application over HTTP or HTTPS.

Patch Information

Oracle addressed CVE-2026-61296 in its Critical Patch Update cycle documented in the August 2026 security alert. Administrators should follow Oracle's standard E-Business Suite patching procedures to apply the fix to all affected 12.2.x releases. Consult the vendor advisory for the exact patch identifiers and prerequisites.

Workarounds

Where patching is delayed, reduce the population of users with access to Linear Asset Management to the minimum required for operations.
Enforce user awareness controls to discourage clicking links from untrusted sources while authenticated to Oracle E-Business Suite.
Deploy a web application firewall in front of Oracle E-Business Suite to inspect and constrain unexpected parameters submitted to Linear Asset Management URLs.
