CVE-2026-115453 — Cross user deletion and modification of cart and wishlist rows in Ecommerce Template through unscoped primary key queries

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.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.2% (30-day exploitation probability)+2
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (MarcosCamara01 Ecommerce Template).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
