How to Fix CVE-2026-12416

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-2026-12416, 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-640: Weak Password Recovery Mechanism for Forgotten Password, where the product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak. 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 Invoice Generator plugin for WordPress is vulnerable to Account Takeover via Password Reset in all versions up to, and including, 1.0.0. This is due to the `pravel_invoice_change_password()` function being registered as a nopriv AJAX handler with no nonce verification and no authorization check, and performing a loose equality comparison between the supplied `reset_activation_code` POST parameter and the target user's stored `forgot_email` user meta — a check that trivially evaluates to true (`'' == ''`) for any user who has never initiated a forgot-password request, which applies to administrators under normal conditions. This makes it possible for unauthenticated attackers to supply an arbitrary user ID via the `reset_user_id` POST parameter, bypass the activation code check entirely by omitting `reset_activation_code`, and set the target account's password to an attacker-chosen value, enabling full takeover of any account on the site, including administrator accounts.
