At a glance
CVE-2025-11196 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the External Login WordPress plugin, affecting versions <= 1.11.2. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed October 2025, reported by Jonas Benjamin Friedli.
Vulnerability Overview
The External Login plugin for WordPress is vulnerable to sensitive information exposure in all versions up to, and including, 1.11.2 due to the 'exlog_test_connection' AJAX action lacking capability checks or nonce validation. This makes it possible for authenticated attackers, with subscriber-level access and above, to query the configured external database and retrieve truncated usernames, email addresses, and password hashes via the diagnostic test results view.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
External Login <= 1.11.2 carries this weakness at exlog_test_connection, and reaching it takes an account at Subscriber level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.
The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. No fixed build of this plugin is recorded for External Login yet, so installs running <= 1.11.2 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
