Administrator access via unchecked capabilities meta write
Published Jul 27, 2026 · Updated Jul 27, 2026
Privilege escalation in Plugin999 Custom Fields Account Registration For WooCommerce before 1.4 allows remote attackers to gain administrator access. The plugin saves attacker-supplied custom registration values as user meta without blocking the real prefixed capabilities key when WordPress uses a non-default table prefix. Exploitation requires WooCommerce account registration and a configured field whose slug matches that key; registration then creates an administrator account.
