CVE-2026-62505: Oracle Time and Labor Auth Bypass Flaw

CVE-2026-62505 Overview

CVE-2026-62505 affects the Oracle Time and Labor product within Oracle E-Business Suite, specifically the Internal Operations component. Supported versions 12.2.3 through 12.2.15 are impacted. An unauthenticated attacker with network access via HTTP can exploit this flaw, but successful exploitation requires human interaction from a user other than the attacker. The vulnerability introduces a scope change, meaning attacks may impact additional Oracle products beyond Time and Labor. Successful exploitation permits unauthorized update, insert, or delete access to a subset of Oracle Time and Labor data, along with limited read access. The weakness is categorized under [CWE-284] (Improper Access Control).

Critical Impact
Remote, unauthenticated attackers can trick a legitimate user into triggering requests that alter or expose Oracle Time and Labor data, with cross-product scope impact across Oracle E-Business Suite.

Affected Products

Oracle E-Business Suite — Oracle Time and Labor 12.2.3
Oracle E-Business Suite — Oracle Time and Labor versions 12.2.4 through 12.2.14
Oracle E-Business Suite — Oracle Time and Labor 12.2.15

Technical Details for CVE-2026-62505

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Time and Labor, part of Oracle E-Business Suite. It is classified as an improper access control weakness [CWE-284]. The attack vector is network-based over HTTP and does not require attacker authentication. Exploitation requires user interaction, consistent with client-assisted attack patterns such as crafted links or forms delivered to an authenticated Oracle E-Business Suite user. Because the vulnerability produces a scope change, code executing within Oracle Time and Labor can influence data or functions in adjacent Oracle E-Business Suite modules. Impact is limited to confidentiality and integrity, with no direct availability effect.

Root Cause

Oracle's advisory attributes the issue to improper access control within the Internal Operations component. Access enforcement fails to fully validate the origin, authorization context, or intent of requests, allowing an attacker-controlled request executed by a victim to perform state-changing operations. The scope change indicates the vulnerable component operates with privileges reaching beyond its own security authority.

Attack Vector

An unauthenticated attacker delivers a crafted HTTP request or link to a user with an active Oracle E-Business Suite session. When the user interacts with the payload, the request executes against Oracle Time and Labor with the victim's session context. The attacker can then modify a subset of Time and Labor data and read limited information, with impact extending across product boundaries. See the Oracle Security Alert July 2026 for advisory details.

No verified public exploit code is available. Refer to Oracle's advisory for technical specifics.

Detection Methods for CVE-2026-62505

Indicators of Compromise

Unexpected HTTP requests to Oracle Time and Labor Internal Operations endpoints originating from external referrers or via user-clicked links.
Unauthorized inserts, updates, or deletes in Oracle Time and Labor tables that do not correlate with legitimate workflow activity.
Session activity where a single user account performs data modifications immediately after visiting an external URL.

Detection Strategies

Enable Oracle E-Business Suite audit logging for the Time and Labor Internal Operations component and review anomalous write operations.
Correlate web server access logs with database audit trails to identify HTTP requests that trigger unexpected data changes.
Monitor for cross-module data access patterns consistent with the documented scope change behavior.

Monitoring Recommendations

Alert on Oracle E-Business Suite HTTP requests referencing Time and Labor endpoints from off-domain referrers.
Baseline normal Time and Labor transaction volumes per user and flag deviations, particularly non-business-hours activity.
Track EPSS scoring updates and Oracle advisory revisions for changes in exploit likelihood.

How to Mitigate CVE-2026-62505

Immediate Actions Required

Apply the Oracle Critical Patch Update fix referenced in the Oracle Security Alert July 2026 to all Oracle E-Business Suite 12.2.3–12.2.15 deployments.
Inventory all Oracle Time and Labor instances and validate patch level after deployment.
Restrict external HTTP access to Oracle E-Business Suite interfaces used internally.

Patch Information

Oracle addressed CVE-2026-62505 in the July 2026 Critical Patch Update. Administrators should download and apply the patch corresponding to their Oracle E-Business Suite 12.2.x release. Consult the Oracle Security Alert July 2026 for patch identifiers, prerequisites, and post-installation validation steps.

Workarounds

Limit user access to Oracle Time and Labor to only personnel with a business requirement, reducing the pool of potential victims.
Enforce strict web browsing controls and email link filtering for users with Oracle E-Business Suite access.
Place Oracle E-Business Suite behind a web application firewall that inspects and filters HTTP requests targeting Time and Labor endpoints.
