Summary
The PZ Frontend Manager plugin for WordPress up to version 1.0.6 contains a missing authorization vulnerability in the pzfm_user_request_action_callback() function. This AJAX function lacks capability checks and nonce verification, allowing authenticated attackers with Subscriber-level access or higher to delete arbitrary WordPress users, including administrators.
Risk Assessment
The risk involves the ability to delete administrator accounts by low-privileged attackers, potentially leading to complete loss of control over the WordPress site.
Recommendation
Immediately update the PZ Frontend Manager plugin to version 1.0.7 or later, which includes a fix for this vulnerability.

OpenAM from 14.0.0 before 16.1.4 contains an information disclosure vulnerability that allows unauthenticated attackers to read live session tokens from the notification WebSocket. Attackers can bypass the agent-only check through an unvalidated internal forward on legacy Liberty ID-FF endpoints, collecting iPlanetDirectoryPro tokens to hijack user and administrator sessions.
- CVE-2026-123550Critical
OpenAM before 16.1.4 contains an authentication bypass vulnerability in its SAML v2.0 service provider that accepts unsigned assertions on the ECP (PAOS) and HTTP-Artifact bindings when WantAssertionsSigned is false. Unauthenticated remote attackers can submit forged assertions to obtain sessions as any mapped user, including administrators, and hijack single sign-on to dependent applications.
- CVE-2026-123549Critical
OpenAM before 16.1.4 fails to enforce the Valid Creation Attributes list during self-registration, allowing anonymous attackers to set restricted attributes including group membership. Attackers can register through the legacy self-service REST endpoint or User Self-Service flow to join administrative groups and gain full administrative control of OpenAM.

Original NVD description (English source)
The PZ Frontend Manager plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.0.6. The pzfm_user_request_action_callback() function, registered via the wp_ajax_pzfm_user_request_action action hook, lacks both capability checks and nonce verification. This function handles user activation, deactivation, and deletion operations. When the 'dataType' parameter is set to 'delete', the function calls wp_delete_user() on all provided user IDs without verifying that the current user has the appropriate permissions. Notably, the similar pzfm_remove_item_callback() function does check pzfm_can_delete_user() before performing deletions, indicating this was an oversight. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary WordPress users (including administrators) by sending a crafted request to the AJAX endpoint.
