What happened

Authorization Bypass Through User-Controlled Key (CWE-639) in the cart and wishlist repositories of MarcosCamara01 Ecommerce Template allows any authenticated user to delete and modify the cart and wishlist rows of any other user, because cartRepository.delete(), cartRepository.updateQuantityInternal() and wishlistRepository.

delete() in src/lib/db/drizzle/repositories/ match rows by primary key alone, with no predicate on the owning user, and the per user authorization for those three operations rests on PostgreSQL row level security. The migrations run ALTER TABLE ... ENABLE ROW LEVEL SECURITY and create policies comparing app.current_user_id() with user_id, but never ALTER TABLE ...

FORCE ROW LEVEL SECURITY, and PostgreSQL does not apply policies to the role that owns a table. The template uses one DATABASE_URL both to run the migrations, which create the tables, and for the application at runtime, so the application connects as the owner of the tables and the policies do not apply to it. cart_items.id and wishlist.

id are sequential bigserial values, so the identifiers of rows belonging to other users can be enumerated, and the update path returns the modified row, which carries the identifier of the user it belongs to. This results in the destruction and modification of cart and wishlist contents belonging to other accounts of the installation.

About this data

This record was ingested from a data source. Retrieved: Oct 27, 2026, 01:40 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.
