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 · unedited
Simple Link Directory through 9.0.4 interpolates the sld_no_results_found option into a JavaScript string literal without encoding. Because sanitize_text_field leaves quotes intact, a stored payload breaks out of the string and runs script for every page visitor.

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 · moderate confidence

Simple Link Directory plugin through 9.0.4 contains a stored XSS vulnerability in the sld_no_results_found option. The plugin uses sanitize_text_field for validation, which preserves quotes, and then interpolates this value directly into a JavaScript string literal without additional encoding. This allows attackers to inject a crafted payload containing quote characters to break out of the JS string and execute arbitrary script in every visitor's browser.

MitigationUpdate to a patched version that properly encodes option values before JavaScript interpolation (e.g., using json_encode or esc_js), or apply a workaround by sanitizing input with quote-encoding before storage.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Simple Link Directory plugin is installed
    Check the WordPress plugins directory for simple-link-directory folder, or view the installed plugins list in WordPress admin under Plugins > Installed Plugins
    Affected if The plugin Simple Link Directory is present in the WordPress installation
  2. Check the plugin version
    Examine the main plugin file (typically simple-link-directory.php) for the 'Version' header or version constant, or view the version column in WordPress admin plugins list
    Affected if The installed version is 9.0.4 or earlier
  3. Locate the sld_no_results_found option in the database
    Query the wp_options table (or equivalent options table with prefix) for option_name = 'sld_no_results_found' using a database tool or WP CLI: wp option get sld_no_results_found
    Affected if The option exists and has a non-empty value set
  4. Inspect the option value for injection markers
    Examine the stored value of sld_no_results_found for unescaped quotes, especially single quotes that could break out of a JavaScript string literal context
    Affected if The option value contains unescaped single quotes or appears to have JavaScript code injection attempts

A user is affected if Simple Link Directory version 9.0.4 or earlier is installed, the sld_no_results_found option is populated, and the option value contains unescaped quotes that could break out of JavaScript string context when the page renders.
