CVE-2025-13656 is a stored cross-site scripting vulnerability in the Cute News Ticker WordPress plugin by arnabkumar. The issue exists in all versions up to and including 1.0, where the 'color' shortcode attribute is not properly sanitized or escaped. This allows authenticated users with Contributor-level permissions or higher to inject arbitrary JavaScript code that executes in the context of users viewing the injected pages. The vulnerability has a CVSS 3.1 base score of 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts confidentiality and integrity with no availability impact. No patch or official fix information is currently available.

An attacker with Contributor-level access or higher can inject persistent malicious scripts into pages via the 'color' shortcode attribute. These scripts execute in the browsers of users who view the compromised pages, potentially leading to unauthorized actions or data disclosure limited to the confidentiality and integrity of the affected site. There is no indication of availability impact or known active exploitation.

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 disabling or removing the Cute News Ticker plugin if possible. Monitor for updates from the plugin author or WordPress security advisories for an official patch or mitigation instructions.
