CVE-2024-0627 is a stored cross-site scripting vulnerability in the Custom Field Template WordPress plugin by hiroaki-miyashita. The issue arises from improper neutralization of input during web page generation, specifically in the custom field name column. Authenticated users with contributor or higher privileges can inject arbitrary scripts due to lack of input sanitization and output escaping. This can lead to script execution in the context of other users viewing the injected pages. The vulnerability affects all versions up to and including 2.6.1. The CVSS 3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and privileges required.

An attacker with contributor-level or higher permissions can inject persistent malicious scripts into pages via the custom field name column. These scripts execute in the context of users who view the affected pages, potentially leading to information disclosure or session hijacking. The impact is limited to confidentiality and integrity with no availability impact. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level permissions to trusted users only. Consider disabling or limiting use of the Custom Field Template plugin if possible. Monitor for updates from the plugin author or WordPress security channels.
