CVE-2024-4014 is a stored cross-site scripting vulnerability in the hCaptcha for WordPress plugin, affecting all versions up to and including 4.0.0. The issue is due to improper neutralization of input during web page generation, specifically insufficient sanitization and output escaping of user-supplied attributes in the plugin's cf7-hcaptcha shortcode. Authenticated attackers with contributor-level privileges or higher can exploit this to inject arbitrary web scripts that execute when the injected page is accessed.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages using the vulnerable shortcode. This can lead to the execution of arbitrary scripts in the context of users viewing those pages, potentially resulting in data theft, session hijacking, or other client-side attacks. The vulnerability does not impact availability but affects confidentiality and integrity to a limited extent.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the cf7-hcaptcha shortcode functionality if feasible to reduce risk.
