CVE-2023-0892Public exploitNetwork attack vector

Stored script execution via unescaped access key

Published May 15, 2023 · Updated Jan 24, 2025

Stored cross-site scripting in the BizLibrary WordPress plugin 1.1 and earlier allows remote authenticated administrators to run script in browsers. The settings handler stores an access-key value without adequate sanitization and renders it without escaping, allowing a crafted value to close the input attribute and inject script. Administrator access is required, and exploitation remains effective when unfiltered_html is disabled, such as on WordPress multisite installations.
