CVE-2026-3361
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 · uneditedThe WP Store Locator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpsl_address' post meta value in versions up to, and including, 2.2.261 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page and opens an injected map marker info window.
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 · high confidenceThe WP Store Locator plugin fails to properly sanitize the 'wpsl_address' post meta input and escape it during output, allowing authenticated users with contributor+ permissions to inject malicious JavaScript via stored XSS that executes when users access injected pages and open map marker info windows.

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.
-
Confirm WP Store Locator plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'WP Store Locator' in the list. Note the version number displayed.
-
Identify the installed plugin versionOn the Plugins page, find WP Store Locator and note the version number shown (e.g., 'Version 2.2.261'). Compare this to the affected range.
-
Verify contributor+ user access existsIn WordPress admin, go to Users > All Users and check if any users have the 'Contributor' role or higher (Author, Editor, Administrator).
-
Inspect database for wpsl_address meta valuesQuery the WordPress postmeta table (typically wp_postmeta) for meta_key 'wpsl_address' using: SELECT * FROM wp_postmeta WHERE meta_key = 'wpsl_address'; Review any stored values for suspicious script tags or unusual HTML.
-
Check for stored XSS in map marker info windowsView a page where the store locator map is displayed. Click on any map marker to open its info window. Inspect the displayed content using browser developer tools (F12) to see if address data is rendered inside script tags or event handlers.
A user is affected if WP Store Locator version 2.2.261 or lower is installed, regardless of whether contributor+ users currently exist on the site.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the WP Store Locator plugin to a version beyond 2.2.261, or implement proper input sanitization and output escaping for the wpsl_address field as an interim measure.
