Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-78065 in the wild and no public exploit code.\n\nAffected product: j2commerce.com J2Store extension for Joomla. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-78065/ (Markdown: https://insights.sbomify.com/CVE-2026-78065/index.md)","id":"CVE-2026-78065","markdown":"https://insights.sbomify.com/CVE-2026-78065/index.md","name":"CVE-2026-78065","record":{"aliases":["GHSA-vwvh-r394-jv9x"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla e-commerce extension","requires_auth":"low_privilege","summary":"Authenticated users can view guest checkout addresses by guessing sequential IDs due to missing authorization checks in J2Store.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"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.
