CVE-2026-90901
📛 CVE Title
Joomla Extension - joomshaper.com - Authenticated, Privileged SQL Injection in Media Image Deletion in Easy Store extension 1.0.0-3.0.0
Description
Joomla Extension - joomshaper.com - Authenticated, Privileged SQL Injection in Media Image Deletion in Easy Store extension 1.0.0-3.0.0 - The checkout.searchGuestUser endpoint allowed querying guest checkout records solely by supplying an email address. The server returned complete shipping details (full name, phone number, street address, city, postal code, and country) directly from the #__easystore_guests table with no authentication, session validation, or ownership checks. An unauthenticated attacker could iterate through email lists to enumerate guest customers and harvest sensitive Personally Identifiable Information (PII). Resolved by removing the unauthenticated server-side guest lookup endpoint entirely and migrating autofill functionality to client-side localStorage protected by explicit user consent.
