CVE-2026-15145 is a stored cross-site scripting vulnerability (CWE-79) in the Essential Addons for Elementor – Popular Elementor Templates & Widgets WordPress plugin. The flaw exists in the Fancy Text Widget due to inadequate input sanitization and output escaping, allowing authenticated attackers with contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute in the context of users who access the compromised pages. The vulnerability affects all plugin versions up to and including 6.6.11. The CVSS 3.1 base score is 6.4, indicating a medium severity with network attack vector, low attack complexity, and no user interaction required.

An attacker with contributor-level access or higher can inject persistent malicious scripts into pages via the Fancy Text Widget. These scripts execute in the browsers of users who visit the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability does not affect availability but impacts confidentiality and integrity.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the Fancy Text Widget to reduce exposure.
