EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 89% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Joomla Extension - j2commerce.com - Guest checkout address disclosure to any authenticated user (IDOR) in J2Store 1.0.0-3.3.21, 4.0.0-4.0.21, 4.1.0-4.1.6 - editAddress() redirected non-owners away only when the loaded address row had a non-empty user_id belonging to someone else. Guest-checkout address rows have an empty user_id, so that check never triggered for them — any logged-in account guessing a small, sequential address_id got a guest customer's full name, street address, and phone number rendered prefilled into the edit form.
