Deeper analysis
The Rescue Shortcodes plugin for WordPress is affected by a stored cross-site scripting vulnerability in all versions through 2.9. The issue resides in the rescue_progressbar shortcode, where insufficient input sanitization and output escaping on user-supplied attributes allow arbitrary script injection, corresponding to CWE-79 with a CVSS 3.1 score of 6.4.
Authenticated attackers holding contributor-level access or higher can exploit the flaw by embedding malicious payloads in shortcode attributes on pages or posts. The injected scripts execute in the browsers of any visitors who view the compromised content, enabling session hijacking, defacement, or theft of sensitive information within the site context.
The referenced WordPress plugin trac and Wordfence advisory point to an available update that addresses the shortcode handling, with the changeset indicating remediation in versions beyond 2.9; site administrators are advised to apply the latest release from the official repository.
EPSS remains flat at 0.1373 with no observed increase after disclosure.
