Deeper analysis

CVE-2024-13351 is a stored cross-site scripting (XSS) vulnerability in the Social proof testimonials and reviews by Repuso plugin for WordPress, affecting all versions up to and including 5.20. The flaw occurs in the plugin's 'rw_image_badge1' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. It has been assigned CWE-79 and a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N), published on 2025-01-15.

Authenticated attackers with contributor-level access or higher can exploit this vulnerability by injecting arbitrary web scripts into pages via the shortcode. The injected scripts will execute in users' browsers whenever they access the affected pages, potentially leading to session hijacking, defacement, or theft of sensitive data from administrators or other users.

Mitigation details are available in referenced advisories, including a patch commit in the WordPress plugin trac at https://plugins.trac.wordpress.org/changeset/3222107/social-testimonials-and-reviews-widget/trunk/social-testimonials-and-reviews-widget.php and a Wordfence threat intelligence report at https://www.wordfence.com/threat-intel/vulnerabilities/id/ff7ead53-4b20-48ba-95cd-118fb4eab330?source=cve.
