A Critical Patch Update is a collection of patches for multiple security vulnerabilities. These patches address vulnerabilities in Oracle code and in third party components included in Oracle products. These patches are usually cumulative, but each advisory describes only the security patches added since the Critical Patch Update Advisory. Thus, prior Critical Patch Update advisories should be reviewed for information regarding earlier published security patches. Refer to “Critical Patch Updates, Security Alerts and Bulletins” for information Oracle Security advisories.

Oracle continues to periodically receive reports of attempts to maliciously exploit vulnerabilities for which Oracle has already released security patches. In some instances, it has been reported that attackers have been successful because targeted customers had failed to apply available Oracle patches. Oracle therefore strongly recommends that customers remain on actively-supported versions and apply Critical Patch Update security patches without delay.

This Critical Patch Update contains 481 new security patches across the product families listed below. Please note that an MOS note summarizing the content of this Critical Patch Update and other Oracle Software Security Assurance activities is located at April 2026 Critical Patch Update: Executive Summary and Analysis .

Please note that since the release of the January 2026 Critical Patch Update, Oracle has released a Security Alert for Oracle Identity Manager and Oracle Web Services Manager, CVE-2026-21992 (March 20, 2026) . Customers are strongly advised to apply the April 2026 Critical Patch Update for Fusion Middleware products, which includes patches for this Alert as well as additional patches.

Security vulnerabilities addressed by this Critical Patch Update affect the products listed below.

Please click on the links in the Patch Availability Document column below to access the documentation for patch availability information and installation instructions.

Risk matrices list only security vulnerabilities that are newly addressed by the patches associated with this advisory. Risk matrices for security patches can be found in Critical Patch Update advisories and Alerts . An English text version of the risk matrices provided in this document is here .

Several vulnerabilities addressed in this Critical Patch Update affect multiple products. Each vulnerability is identified by a CVE ID . A vulnerability that affects multiple products will appear with the same CVE ID in all risk matrices.

Security vulnerabilities are scored using CVSS version 3.1 (see Oracle CVSS Scoring for an explanation of how Oracle applies CVSS version 3.1).

Oracle conducts an analysis of each security vulnerability addressed by a Critical Patch Update. Oracle does not disclose detailed information this security analysis to customers, but the resulting Risk Matrix and associated documentation provide information conditions required to exploit the vulnerability and the potential impact of a successful exploit. Oracle provides this information so that customers may conduct their own risk analysis based on the particulars of their product usage. For more information, see Oracle vulnerability disclosure policies .

Third party component vulnerabilities that are deemed not exploitable in the context of their inclusion in an Oracle product are listed, with VEX justifications, below the respective Oracle product's risk matrix.

The protocol in the risk matrix implies that all of its secure variants are affected as well. For example, if HTTP is listed as an affected protocol, it implies that HTTPS is also affected. The secure variant of a protocol is listed in the risk matrix only if it is the only variant affected.

Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply Critical Patch Update security patches as soon as possible . Until you apply the Critical Patch Update patches, it may be possible to reduce the risk of successful attack by blocking network protocols required by an attack. For attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from users that do not need the privileges may help reduce the risk of successful attack. Both approaches may break application functionality, so Oracle strongly recommends that customers test changes on non-production systems. Neither approach should be considered a long-term solution as neither corrects the underlying problem.

Oracle strongly recommends that customers apply security patches as soon as possible. For customers that have skipped one or more Critical Patch Updates and are concerned products that do not have security patches announced in this Critical Patch Update, please review Critical Patch Update advisories to determine appropriate actions.

Patches released through the Critical Patch Update program are provided only for product versions that are covered under the Premier Support or Extended Support phases of the Lifetime Support Policy . Oracle recommends that customers plan product upgrades to ensure that patches released through the Critical Patch Update program are available for the versions they are currently running.

Product releases that are not under Premier Support or Extended Support are not tested for the presence of vulnerabilities addressed by this Critical Patch Update. However, it is likely that earlier versions of affected releases are also affected by these vulnerabilities. As a result, Oracle recommends that customers upgrade to supported versions.

Database, Fusion Middleware, and Oracle Enterprise Manager products are patched in accordance with the Software Error Correction Support Policy that further supplements the Lifetime Support Policy as explained in My Oracle Support Note KB65129 . Please review the Technical Support Policies for further guidelines regarding support policies and phases of support.
