CVE-2026-5714 describes a stored cross-site scripting vulnerability in the Enable Media Replace plugin for WordPress, affecting all versions up to and including 4.1.8. The issue is due to improper neutralization of input in the 'location_dir' parameter, allowing authenticated attackers with Author-level access or higher to inject arbitrary web scripts. These scripts execute in the context of users who access the injected pages, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, privileges required at the Author level, no user interaction needed, and partial impact on confidentiality and integrity.

An attacker with Author-level privileges can inject persistent malicious scripts via the vulnerable parameter, which execute in the browsers of users viewing the affected pages. This can lead to partial confidentiality and integrity compromise, such as theft of session tokens or unauthorized actions performed on behalf of users. Availability is not impacted.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Author-level access to trusted users only and consider additional input validation or output escaping controls if possible. Monitor vendor channels for updates or patches addressing this vulnerability.
