CVE-2026-62527: Oracle Learning Management Auth Bypass

CVE-2026-62527 Overview

CVE-2026-62527 affects the Import and Export component of Oracle Learning Management within Oracle E-Business Suite. The flaw impacts supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit the weakness without user interaction. Successful exploitation allows unauthorized update, insert, or delete operations on a subset of accessible data. Attackers can also read a subset of data and cause a partial denial of service. The underlying weakness maps to [CWE-89] SQL Injection.

Critical Impact
A low-privileged attacker over HTTP can modify or read a subset of Oracle Learning Management data and cause a partial denial of service without user interaction.

Technical Details for CVE-2026-62527

Vulnerability Analysis

The vulnerability resides in the Import and Export functionality of Oracle Learning Management. The component processes HTTP-borne input without adequate sanitization before it reaches backend database operations. An authenticated user with minimal privileges can send crafted requests that alter the intended SQL structure. The result is targeted read, write, and availability impact on a subset of Learning Management data.

Exploitation is network-reachable and requires only low privileges. No user interaction is needed, which raises exposure in environments where broad user populations receive Learning Management accounts. The scope remains unchanged, and impact is limited to the Learning Management application context rather than the underlying host.

Root Cause

The root cause is improper neutralization of special elements used in an SQL command, categorized as [CWE-89]. The Import and Export code path constructs database queries using input that an authenticated user controls. Because the input is not consistently parameterized or validated, attackers can inject SQL fragments that the database engine executes. Oracle's advisory in the July 2026 Critical Patch Update confirms the confidentiality, integrity, and availability impact.

Attack Vector

The attack vector is network-based over HTTP against the Oracle E-Business Suite front end. An attacker authenticates with any low-privileged Learning Management account. The attacker then submits crafted Import or Export requests that embed SQL payloads in fields consumed by the vulnerable component. Successful requests yield unauthorized data reads, unauthorized data modification, or partial service disruption. See the Oracle Critical Patch Update - July 2026 for advisory details.

Detection Methods for CVE-2026-62527

Indicators of Compromise

Unexpected Import or Export requests from low-privileged Learning Management accounts, particularly those containing SQL metacharacters such as single quotes, UNION, --, or ;.
Oracle E-Business Suite audit records showing anomalous SELECT, INSERT, UPDATE, or DELETE operations tied to the Learning Management schema outside routine business hours.
Application error responses referencing malformed SQL or ORA-prefixed database errors correlated with Learning Management URLs.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and Page Access Tracking for Learning Management Import and Export functions.
Deploy a Web Application Firewall (WAF) rule set targeting SQL injection patterns in HTTP parameters submitted to Learning Management endpoints.
Baseline typical Import and Export payload sizes and structures, then alert on deviations that suggest injected SQL syntax.

Monitoring Recommendations

Forward Oracle E-Business Suite application, database, and web tier logs to a centralized analytics platform for correlation and long-term retention.
Track authentication events for Learning Management users and flag session sources that exhibit rapid Import or Export activity.
Monitor database performance counters for query anomalies that align with partial denial-of-service behavior described in the advisory.

How to Mitigate CVE-2026-62527

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite instances running Learning Management versions 12.2.3 through 12.2.15.
Inventory Learning Management user accounts and revoke access from users who do not require Import or Export privileges.
Restrict network access to the Oracle E-Business Suite front end to trusted corporate ranges and VPN concentrators.

Patch Information

Oracle addressed CVE-2026-62527 in the July 2026 Critical Patch Update. Administrators should download the fix package referenced in the Oracle Critical Patch Update - July 2026 advisory and apply it in accordance with Oracle's E-Business Suite patching guidance. Test the patch in a non-production environment before rolling out to production.

Workarounds

Place a WAF or reverse proxy in front of Oracle E-Business Suite and block requests containing SQL injection signatures to Learning Management Import and Export URLs.
Temporarily disable the Import and Export function for Learning Management if a patch cannot be applied within your standard maintenance window.
Enforce least-privilege role assignments so that only administrators retain access to data-import capabilities within Learning Management.
