CVE-2026-12231 is a stored cross-site scripting vulnerability in the Exclusive Addons for Elementor WordPress plugin. The issue exists in the 'exad_infobox_image' parameter, allowing authenticated attackers with Contributor-level or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users who access the compromised pages. The vulnerability affects all versions up to and including 2.7.9.8 due to improper neutralization of input during web page generation. The CVSS 3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and no user interaction required. Confidentiality and integrity impacts are low, with no availability impact. No official patch or remediation guidance is currently provided.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable parameter. These scripts execute in the browsers of users who view the infected pages, potentially leading to theft of sensitive information or unauthorized actions within the context of the affected site. The impact is limited to confidentiality and integrity with no direct availability impact.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Contributor-level access to trusted users only and consider additional input validation or output escaping controls if possible. Monitor for updates from the vendor or security community regarding patches or official mitigations.
