dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Block Slider plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and search for 'Block Slider' or 'block slider'. Confirm the plugin is present and activated.Affected if The Block Slider plugin is installed and active on the WordPress site
