Title source: cnaExploitation Summary
EIP tracks 1 public exploit for CVE-2026-13152. PoCs published by incogbyte.
AI-analyzed exploit summary This exploit demonstrates an unauthenticated privilege escalation vulnerability in the 'Custom Fields Account Registration For WooCommerce' plugin (<=1.3) by abusing unblocked user-meta writes during WooCommerce registration. Attackers can inject arbitrary capabilities (e.g., administrator role) by submitting crafted values to a pre-existing custom registration field whose slug matches the site's actual '<table_prefix>capabilities' meta key.
Description
The Custom Fields Account Registration For Woocommerce WordPress plugin before 1.4 does not prevent its custom registration fields from writing to the user capabilities meta key on sites that use a non-default database table prefix, so an unauthenticated user who registers an account can be granted the administrator role when a correspondingly named field has been configured.
