Oracle Critical Security Patch Update Advisory - September 2026

Description

A Critical Security Patch Update (CSPU) provides targeted, high-priority security fixes in a smaller, more focused format, making them easier to apply with minimal disruption. Critical Security Patch Updates complement Oracle’s existing quarterly cumulative Critical Patch Updates (CPUs). These patches address vulnerabilities in Oracle code and in third party components included in Oracle products. Prior Critical Patch Update and Critical Security Patch Update advisories should be reviewed for information regarding earlier published security patches. Refer to Critical Patch Updates, Critical Security Patch Updates, Security Alerts and Bulletins for information about 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 security patches without delay.

This Critical Security Patch Update contains 673 new security patches across the product families listed below. Please note that a My Oracle Support (MOS) note summarizing the content of this Critical Security Patch Update and other Oracle Software Security Assurance activities is located at September 2026 Critical Security Patch Update: Executive Summary and Analysis.

Affected Products and Patch Information

Security vulnerabilities addressed by this Critical Security 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 Matrix Content

Risk matrices list only security vulnerabilities that are newly addressed by the patches associated with this advisory. Risk matrices for previous security patches can be found in previous Critical Patch Update advisories, Critical Security 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 Security 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 Security Patch Update. Oracle does not disclose detailed information about this security analysis to customers, but the resulting Risk Matrix and associated documentation provide information about 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.

Workarounds

Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply Critical Security Patch Update security patches as soon as possible. Until you apply the Critical Security 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.

Skipped Security Patch Updates

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

Critical Security Patch Update Supported Products and Versions

Patches released through the Critical Security 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 Security 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 Security 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.
