CVE-2026-0626 is a stored cross-site scripting vulnerability affecting the WPFunnels plugin for WordPress. The issue arises from improper neutralization of input in the 'button_icon' parameter within the 'wpf_optin_form' shortcode, allowing authenticated users with contributor or higher privileges to inject arbitrary scripts. These scripts execute in the context of users who visit the compromised pages, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to 3.7.9. The CVSS 3.1 score is 6.4 (medium), reflecting network attack vector, low attack complexity, privileges required, no user interaction, and partial confidentiality and integrity impact. No patch or official fix has been documented as of the published date.

An attacker with contributor-level or higher access can inject malicious JavaScript code into pages via the vulnerable shortcode parameter. This code executes in the browsers of users who view the infected pages, potentially leading to theft of sensitive information or session tokens. The vulnerability does not impact availability. There are no known exploits in the wild at this time.

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 removing or disabling the vulnerable shortcode if feasible. Monitor updates from the vendor for a security patch.
