WordPress vulnerability analysis and mitigation

The B Testimonial WordPress plugin (versions up to 1.2.2) has been identified with a Stored Cross-Site Scripting vulnerability, tracked as CVE-2024-11880. The vulnerability was discovered by Peter Thaleikis and publicly disclosed on December 3, 2024. This security issue affects the plugin's 'b_testimonial' shortcode functionality (NVD, Wordfence).

The vulnerability is classified as a Stored Cross-Site Scripting (CWE-79) issue that stems from insufficient input sanitization and output escaping on user-supplied attributes in the 'b_testimonial' shortcode. The severity is rated as Medium with a CVSS v3.1 base score of 6.4 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N) (NVD).

When exploited, this vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever a user accesses the compromised page, potentially leading to data theft or unauthorized actions performed on behalf of visiting users (NVD).

Users of the B Testimonial plugin should update to a version newer than 1.2.2 if available. If an update is not possible, it is recommended to restrict access to the plugin's functionality to trusted users only (NVD).
