CVE-2026-62563: Oracle Work in Process Auth Bypass Flaw

CVE-2026-62563 Overview

CVE-2026-62563 affects the Oracle Work in Process product within Oracle E-Business Suite (EBS), specifically the Internal Operations component. Supported versions 12.2.5 through 12.2.15 are impacted. A low-privileged attacker with network access via HTTP can exploit this authorization flaw [CWE-285] to compromise Oracle Work in Process. Successful exploitation requires human interaction from a user other than the attacker. Because the vulnerability produces a scope change, attacks may affect additional Oracle products beyond Work in Process itself.

Critical Impact
Successful attacks enable unauthorized update, insert, or delete access to a subset of Oracle Work in Process data, plus unauthorized read access to a subset of that data, with potential impact extending beyond the vulnerable component.

Affected Products

Oracle E-Business Suite - Oracle Work in Process 12.2.5
Oracle E-Business Suite - Oracle Work in Process 12.2.6 through 12.2.14
Oracle E-Business Suite - Oracle Work in Process 12.2.15

Technical Details for CVE-2026-62563

Vulnerability Analysis

CVE-2026-62563 is an improper authorization vulnerability [CWE-285] in the Internal Operations component of Oracle Work in Process. An authenticated user with low privileges can send crafted HTTP requests that bypass expected authorization checks. Because the vulnerability requires user interaction from a distinct victim, exploitation typically follows a social-engineering vector such as a crafted link or an application workflow that induces the victim to submit an authenticated action.

The scope change indicates that a compromise in Work in Process can influence data or components controlled by other security authorities within Oracle EBS. This amplifies the impact beyond a single module and complicates blast-radius assessment.

Root Cause

The root cause is missing or improperly enforced authorization within the Internal Operations component. Authorization decisions do not sufficiently validate the requesting principal against the resource or operation, allowing lower-privileged users to trigger writes and reads they should not have.

Attack Vector

Exploitation occurs over the network via HTTP against an Oracle EBS instance running an affected Work in Process version. The attacker must possess valid low-privileged credentials and must lure a separate authenticated user into interacting with a crafted request or link. Once triggered, the authorization gap permits unauthorized create, update, delete, and limited read operations against accessible Work in Process data.

No verified proof-of-concept code is publicly available. Refer to the Oracle Critical Patch Update - July 2026 for vendor technical details.

Detection Methods for CVE-2026-62563

Indicators of Compromise

Unexpected modifications to Work in Process records (job status, routing, resource allocations) that do not correspond to a legitimate workflow event.
HTTP requests to Internal Operations endpoints originating from user sessions whose role should not permit those operations.
Cross-module data changes in Oracle EBS that trace back to a Work in Process session, reflecting the scope-change behavior.

Detection Strategies

Enable Oracle EBS Sign-On Audit and Page Access Tracking to log user activity against Work in Process forms and Internal Operations URLs.
Correlate application-tier access logs with database audit records to identify writes performed by users lacking the corresponding responsibility.
Baseline normal Work in Process transaction patterns per user role and alert on deviations, particularly INSERT, UPDATE, or DELETE operations by low-privileged accounts.

Monitoring Recommendations

Forward Oracle EBS application, concurrent manager, and database audit logs to a centralized analytics platform such as SentinelOne Singularity Data Lake for OCSF-normalized retention and search.
Monitor for phishing or social-engineering campaigns targeting EBS users, since exploitation requires victim interaction.
Track outbound links delivered to EBS users and inspect referrer chains landing on Internal Operations endpoints.

How to Mitigate CVE-2026-62563

Immediate Actions Required

Apply the Oracle Critical Patch Update from July 2026 to all Oracle E-Business Suite 12.2.5-12.2.15 environments running Work in Process.
Inventory all EBS instances and identify low-privileged user accounts with access to Work in Process responsibilities for review.
Reinforce user awareness training to reduce the likelihood of the required victim interaction being successful.

Patch Information

Oracle addressed CVE-2026-62563 in the Oracle Critical Patch Update - July 2026. Administrators should apply the vendor-supplied patches for Oracle E-Business Suite 12.2 following Oracle's documented CPU installation procedure and validate the patch level with adop and OPatch lsinventory after deployment.

Workarounds

Restrict network exposure of Oracle EBS Internal Operations endpoints to trusted internal networks and VPN clients.
Remove or narrow Work in Process responsibilities from users who do not require them, reducing the population of accounts able to initiate an attack.
Enforce strong session management, short session timeouts, and re-authentication for sensitive Work in Process transactions until the CPU is applied.
