Am I affected?

dbcve checks

Work through these to decide whether this CVE applies to you.

Confirm Oracle E-Business Suite installation

Locate Oracle E-Business Suite installation directories or running processes (such as Oracle database and application server processes) on the target system

Affected if The system does not run Oracle E-Business Suite
Identify installed E-Business Suite version

Query the installed version using Oracle utilities (such as adident, SQL queries against FND_PRODUCT_GROUPS, or the Oracle Applications Manager interface) to determine the exact version number

Affected if The installed version is 12.2.11, 12.2.12, 12.2.13, 12.2.14, or 12.2.15 (within the 12.2.11 through 12.2.15 range)
Verify Oracle Applications Framework Web Utilities is enabled

Check the Oracle E-Business Suite configuration for the Web Utilities module within Oracle Applications Framework. This may involve examining the Oracle Applications Manager module status, checking for WebUtil-related schema objects, or reviewing the applications context file

Affected if Web Utilities component is present and enabled in the Oracle Applications Framework configuration
Confirm HTTP network exposure

Verify that the Oracle E-Business Suite web interfaces (OA_HTML, OA_JAVA servlets, or related web entry points) are accessible over HTTP/HTTPS from the network. Check firewall rules, load balancer configurations, and web listener bindings

Affected if The E-Business Suite web tier is exposed to network access via HTTP

A system is affected if it runs Oracle E-Business Suite versions 12.2.11 through 12.2.15 with the Oracle Applications Framework Web Utilities component enabled and accessible over HTTP network.

Generated from the published advisory. Verify against your own configuration.

Remediation

dbcve · scoped

Upgrade available Upgrade to a release after 12.2.15

Interim mitigation

Apply the relevant Oracle Critical Patch Update (CPU) for Oracle E-Business Suite that addresses CVE-2026-62534. Prior to deployment in production, validate the patch in a non-production environment due to the complexity of Oracle EBS implementations.

Recommended fix Moderate confidence

Apply Oracle E-Business Suite 12.2.16 or later (or the latest CPU patch for your current version line)

1. Check Oracle's Official Critical Patch Update (CPU) advisory for CVE-2026-62534 at https://www.oracle.com/security-alerts/
2. Navigate to Oracle E-Business Suite Support documentation and locate the corresponding patch for your specific version (12.2.11, 12.2.12, 12.2.13, 12.2.14, or 12.2.15)
3. Download the recommended security patch from Oracle Support (MOS - My Oracle Support)
4. Review the patch readme and pre-install requirements
5. Apply the patch in a test environment first to validate compatibility
6. Apply the patch to production during a scheduled maintenance window
7. Verify the patch was applied successfully and conduct post-installation testing

Caveat Review Oracle's patch prerequisites and consider testing in a non-production environment before applying to production; some patches may require additional setup or have dependencies

Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
