DescriptionThe 24liveblog - live blog tool plugin for WordPress is vulnerable to Exposure of Sensitive Information in versions up to, and including, 2.2. This is due to the lb24_block_enqueue_scripts() function being hooked to enqueue_block_editor_assets and, for any non-administrator user, falling back to loading the administrator-configured site-wide 24liveblog integration secrets (lb24_token, lb24_refresh_token, lb24_uid, lb24_uname) from the options table via get_option() and emitting them through wp_localize_script() as the lb24BlockData JavaScript object. This makes it possible for authenticated attackers, with contributor-level access and above, to extract third-party 24liveblog account credentials (including the API token and refresh token) by simply opening the block editor and inspecting the page source.
