What happened

The Advanced Members for ACF plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.3.0 via the acf[_amem_local_user_password] parameter of the [advanced-members-account-password] shortcode form submission. This is due to a PHP operator-precedence bug in the pre_update_value function of acf/fields/class-user-password.

php that assigns boolean true instead of the resolved user ID to $user_id, causing the _can_edit() authorization check to pass for any logged-in user via PHP loose equality, and causing wp_update_user() to cast 'ID' => true to integer 1 — unconditionally targeting the primary administrator account.

This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the password of user ID 1 (the site's primary administrator) with an attacker-chosen value, granting full administrative access to the site.

The intended exclusion guard in Account::process that strips the password field before saving is defeated because amem_save_all_fields() re-reads the full field list from amem()->submission and silently overwrites the caller-supplied excluded fields array with an empty array, ensuring the password field is always processed.

About this data

This record was ingested from a data source. Retrieved: Nov 6, 2026, 13:50 UTC. Ingestion is not an independent editorial investigation.

NVD status: Deferred. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
