Technical details
An operator precedence error in the cleanExpiryProdList SQL query allows the WHERE clause to match any user's cart row when a product is off-shelf, rather than only the authenticated caller's expired items. The vulnerable query uses OR with AND in improper order: `tp.status = 0 OR ts.status = 0 AND tb.user_id = ?` evaluates as `tp.status = 0 OR (ts.status = 0 AND tb.user_id = ?)`, so any row with an off-shelf product matches regardless of user_id. A single DELETE request to /p/shopCart/cleanExpiryProdList removes cart entries across all users.
Affected products
