- CVE-2026-103900, 7 Nov 2026
- The WPJAM Basic plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 7.1 This is due to the WPJAM_User_Signup::signup() function unpacking attacker-supplied `data[args]` from the AJAX POST body and merging it via PHP array union into the payload passed to WPJAM_User::create(), whose internal whitelist (wpjam_pick) explicitly preserves the `role` key before it is handed to wp_insert_user(). The endpoint is registered as wp_ajax_nopriv_{provider}-signup with a nonce that is emitted on the public login page. This makes it possible for unauthenticated attackers to elevate their privileges to Administrator by creating a new user with an attacker-chosen role, provided a social-login provider is registered and open registration is enabled. CVE record
What to do if you run WPJAM Basic
If you run WPJAM Basic, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
