How to Fix CVE-2026-19965

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-2026-19965, 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-203: Observable Discrepancy, where the product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor. 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

A vulnerability was determined in automad up to 2.0.0-beta.32. This vulnerability affects the function requestPasswordResetToken of the file automad/src/server/Controllers/API/UserController.php of the component Password Reset Endpoint. This manipulation of the argument name-or-email causes observable response discrepancy. The attack can be initiated remotely. The attack's complexity is rated as high. It is stated that the exploitability is difficult. The exploit has been publicly disclosed and may be utilized. Upgrading to version 2.0.0-beta.33 is able to resolve this issue. Patch name: eac0b05dafdb0ddf8b9139dad8929aaba86568ca. You should upgrade the affected component.
