Advisory Summary

CVE-2026-78579 is a MODERATE (CVSS 6.8) security vulnerability vulnerability (CWE-90: Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product constructs all or part of an ldap query using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended ldap query when it is sent to a downstream component.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-78579

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-78579, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-90: Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection'), where the product constructs all or part of an ldap query using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended ldap query when it is sent to a downstream component. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The Okta Access Gateway does not sanitize SAML assertion attribute values before interpolating them into LDAP search filters in the LDAP datastore configuration. The raw values are substituted directly into the filter string and passed to the LDAP search operation, resulting in modification of the intended query logic.
