CVE-2025-1777
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe BM Content Builder plugin for WordPress is vulnerable to unauthorized modification of data to a missing capability check on the 'ux_cb_page_options_save' function in all versions up to, and including, 3.16.2.1. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe BM Content Builder WordPress plugin is vulnerable to Broken Access Control allowing any authenticated user with subscriber-level access or higher to call the 'ux_cb_page_options_save' function without authorization, enabling injection of arbitrary JavaScript (stored XSS) into pages.
