CVE-2025-11177
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 External Login plugin for WordPress is vulnerable to SQL Injection via the 'log' parameter in all versions up to, and including, 1.11.2 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 when a PostgreSQL or MSSQL database is configured as the external authentication 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 External Login WordPress plugin versions up to 1.11.2 contain an unauthenticated SQL injection vulnerability in the 'log' parameter. Due to insufficient escaping of user input and lack of prepared statements in the SQL query, attackers can append malicious SQL commands. This is only exploitable when PostgreSQL or MSSQL is configured as the external authentication database, as these databases handle SQL concatenation differently than MySQL.

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.
-
Locate the External Login plugin and identify its versionAccess the WordPress wp-content/plugins/ directory and locate the external-login plugin folder. Open the main plugin PHP file (typically external-login.php) and look for the version declaration in the plugin header comment, or check the readme.txt file for the Version field.Affected if The installed version is 1.11.2 or any earlier version (the plugin version is at or below 1.11.2).
-
Verify the external authentication database typeExamine the WordPress configuration (wp-config.php) and the External Login plugin settings to determine which database type is configured for the external authentication connection. Look for database connection parameters that specify PostgreSQL or MSSQL.Affected if The external authentication database is configured as PostgreSQL or MSSQL (this vulnerability does not apply when using MySQL).
-
Confirm the plugin is active with external database configuredCheck the WordPress admin plugin status to confirm the External Login plugin is enabled, then review the plugin configuration to verify that an external authentication database connection is actually configured and in use.Affected if The plugin is active and has an external PostgreSQL or MSSQL authentication database configured and connected.
A user is affected if they have the External Login plugin installed at version 1.11.2 or lower AND have PostgreSQL or MSSQL configured as their external authentication database, with the plugin active and the external auth feature enabled.

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 External Login plugin to the latest patched version once released. If immediate patching is not possible, consider disabling the plugin or implementing WAF rules to block SQL injection attempts targeting the 'log' parameter.
External Login plugin version 1.11.3 or higher
- 1. Update the External Login WordPress plugin to version 1.11.3 or later through the WordPress admin dashboard (Plugins > Updates Available), or
- 2. If automatic updates are not enabled, navigate to Plugins > Add New > Upload Plugin and upload the latest version from wordpress.org/plugins/external-login/, or
- 3. Alternatively, download the latest version from wordpress.org and manually upload via FTP or the WordPress file manager
