Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check the installed version of Hash ElementsNavigate to WordPress admin > Plugins > Installed Plugins, locate Hash Elements, and note the version number displayedAffected if The version shown is lower than 1.3.4
-
Identify Hash Elements input fields in useReview pages/posts where Hash Elements widgets or elements are added; note any text input fields, form fields, or content areas provided by the pluginAffected if The plugin is actively used with input-receiving elements on the site

-
View affected pages as a logged-out or low-privilege userOpen the frontend pages containing Hash Elements content while logged out or as a subscriber-level user to observe if stored script content executes in the browserAffected if Malicious JavaScript or HTML executes when viewing pages containing Hash Elements data
-
Review plugin source code for output escapingIf you have access to the plugin files, inspect the template files and PHP rendering code for the presence of escaping functions such as esc_html(), esc_attr(), or wp_kses() when outputting plugin-stored valuesAffected if Output functions are missing and user-supplied data is rendered without encoding
You are affected if Hash Elements version is below 1.3.4 AND the plugin is in use with input fields that store data without sanitization, allowing injected scripts to execute when viewed by other users.
