The vulnerability was disclosed on November 4, 2025, and affects the 'reuse_builder_single_post_title' shortcode functionality (NVD, Wordfence).

The vulnerability stems from insufficient input sanitization and output escaping on the 'style' attribute within the 'reuse_builder_single_post_title' shortcode. The issue has been assigned a CVSS v3.1 base score of 6.4 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N.

When exploited, this vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages.

The plugin has been temporarily closed as of October 31, 2025, pending a full security review. Users are advised to disable the plugin until a patched version is released (WordPress).
