Unauthenticated Privilege Escalation in WordPress Invoice Generator <= 1.0.0

IdentifiersCVE-2026-12415CWE-862

CVE-2026-12415 is a critical privilege escalation vulnerability in the Invoice Generator plugin for WordPress affecting versions up to and including 1.0.0. The flaw is in the pravel_invoice_edit_account() AJAX action, which is exposed to unauthenticated users via wp_ajax_nopriv_pravel_invoice_edit_account. The handler accepts attacker-controlled user_id and user_email values from POST data and invokes wp_update_user() without enforcing authentication, capability checks, ownership validation, or nonce verification. As a result, a remote unauthenticated attacker can modify the email address associated with an arbitrary WordPress user account, including an administrator account, and then leverage the standard WordPress password reset workflow to reset the victim account password and take over the account.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows unauthenticated remote attackers to take over arbitrary WordPress accounts, including administrator accounts. This can result in full compromise of the affected site through administrative access, including unauthorized modification of site content and configuration, installation of malicious plugins or backdoors, access to sensitive data available to the compromised account, and potential follow-on actions such as persistence and further privilege abuse within the WordPress environment.

Mitigation

If you can’t patch tonight, do this now.

As an immediate mitigation, disable or uninstall the Invoice Generator plugin on affected WordPress instances if a patched version is not yet available. Restrict access to vulnerable AJAX functionality where possible, monitor for unauthorized changes to user email addresses, review password reset activity for privileged accounts, and audit administrator and other high-value accounts for signs of takeover. Reset credentials and restore legitimate account email addresses for any suspected compromised users.

Remediation

Patch, then assume compromise.

Update the Invoice Generator plugin to a patched version newer than 1.0.0 if one is available from the vendor. The vulnerable AJAX action should be corrected by removing unauthenticated exposure where not required, enforcing authentication and authorization checks before allowing account changes, validating that the acting user is permitted to modify the target account, and implementing nonce verification for the request. If no patched release is available, disable or remove the plugin until a fix is provided.
