CVE-2025-5567 is a stored cross-site scripting vulnerability in the WP Shortcodes Plugin — Shortcodes Ultimate for WordPress. The issue is due to improper neutralization of input in the 'data-url' attribute, allowing authenticated users with Contributor-level privileges or above to inject arbitrary web scripts. These scripts execute when any user accesses the compromised page. The vulnerability affects all plugin versions up to 7.4.0. 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. The vulnerability impacts confidentiality and integrity but not availability. No patch or vendor advisory is currently provided.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable 'data-url' attribute. This can lead to unauthorized script execution in users' browsers, potentially compromising user data confidentiality and integrity. The vulnerability does not affect system availability. Since the attacker must be authenticated with at least Contributor privileges, the risk is limited to environments where such user roles exist. 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 released, restrict Contributor-level access to trusted users only. Consider disabling or removing the WP Shortcodes Plugin — Shortcodes Ultimate if feasible. Monitor for plugin updates and apply any official patches promptly once available.
