CVE-2026-4834
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 ERP Pro plugin for WordPress is vulnerable to SQL Injection via the 'search_key' parameter in all versions up to, and including, 1.5.1. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
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 ERP Pro plugin for WordPress versions up to 1.5.1 contains a SQL Injection vulnerability in the 'search_key' parameter. The plugin fails to properly escape user input and does not use prepared statements, allowing unauthenticated attackers to inject arbitrary SQL queries and extract sensitive data from the database.

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.
-
Verify WP ERP Pro plugin versionAccess WordPress admin dashboard, navigate to Plugins section, find WP ERP Pro in the list, and note the installed version number. Alternatively, check the plugin header comment in wp-content/plugins/wp-erp-pro/includes/erp.php or the main plugin file.Affected if Installed version is lower than 1.5.2 (all prior versions are affected)
-
Confirm plugin is activeIn WordPress admin, go to Plugins > Installed Plugins and verify that WP ERP Pro is activated.Affected if Plugin is active and version is below 1.5.2 - an inactive plugin is not exploitable
-
Identify exposure to search_key parameterThe vulnerability lies in the search functionality that processes the 'search_key' parameter in SQL queries. Determine if any public-facing endpoint or API route accepts this parameter by examining plugin code or monitoring HTTP requests to the site.Affected if The search feature is accessible to unauthenticated users and the plugin version is below 1.5.2
You are affected if WP ERP Pro plugin is active and the installed version is below 1.5.2, as the unauthenticated SQL injection via the search_key parameter can be exploited.

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.
dbcve · scopedUpdate the WP ERP Pro plugin to a version beyond 1.5.1 that patches this vulnerability, or apply code fixes to use proper escaping and prepared statements for the 'search_key' parameter in all SQL queries.
WP ERP Pro version 1.5.2 or later
- 1. Navigate to the WordPress admin dashboard and go to Plugins > Installed Plugins
- 2. Locate the WP ERP Pro plugin
- 3. Check the current installed version (visible in the plugin list)
- 4. Update the plugin to the latest available version from the WordPress plugin repository or from WP ERP's official website
- 5. After updating, verify the new version number reflects 1.5.2 or higher
