Advisory Summary

CVE-2026-14249 is a HIGH (CVSS 7.5) security vulnerability vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-14249

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-2026-14249, 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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted 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 Request a Quote plugin for WordPress is vulnerable to Code Injection in versions up to, and including, 2.5.5 via the emd_delete_file AJAX action. This is due to the emd_delete_file() handler deriving a PHP function name from the attacker-controlled $_POST['path'] parameter and invoking it dynamically via the variable-function call $sess_name(), and the handler being registered for wp_ajax_nopriv with its only protection being a nonce that the plugin prints into the public quote-form page via wp_localize_script. This makes it possible for unauthenticated attackers to invoke arbitrary zero-argument PHP functions on the server, such as phpinfo(), potentially exposing sensitive server configuration and credentials, or executing other destructive built-in PHP functions.
