{"id":"CVE-2026-40098","aliases":["GHSA-665x-ppc4-685w"],"url":"https://o3.security/vulnerability/CVE-2026-40098","summary":"OpenMage LTS imports cross-user wishlist item via shared wishlist code, leading to private option disclosure and file-disclosure variant","details":"Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the Magento Community Edition e-commerce platform with a high level of backward compatibility. Prior to version 20.17.0, the shared wishlist add-to-cart endpoint authorizes access with a public `sharing_code`, but loads the acted-on wishlist item by a separate global `wishlist_item_id` and never verifies that the item belongs to the shared wishlist referenced by that code. This lets an attacker use a valid shared wishlist code for wishlist A and a wishlist item ID belonging to victim wishlist B to import victim item B into the attacker's cart through the shared wishlist flow for wishlist A. Because the victim item's stored `buyRequest` is reused during cart import, the victim's private custom-option data is copied into the attacker's quote. If the product uses a file custom option, this can be elevated to cross-user file disclosure because the imported file metadata is preserved and the download endpoint is not ownership-bound. Version 20.17.0 patches the issue.","published":"2026-04-20T16:19:55.157Z","modified":"2026-08-07T11:31:34.765189926Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"openmage/magento-lts","fixedVersion":"20.17.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40098.json"},{"type":"ADVISORY","url":"https://github.com/OpenMage/magento-lts/security/advisories/GHSA-665x-ppc4-685w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40098"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:34.765189926Z"}}
