{"id":"CVE-2026-56829","summary":"Shopper: Unauthorized inventory stock manipulation via unlocked variant property in VariantStock component","details":"Shopper is a Headless e-commerce Admin Panel. Prior to 2.9.2, packages/admin/src/Livewire/Components/Products/VariantStock.php exposes stockAction() without edit_product_variants authorization and leaves public $variant client mutable because it lacks the Livewire Locked attribute. Any authenticated admin-panel user, including staff with only browse_products, can select an arbitrary product variant and inventory location through component state, then submit a positive or negative quantity adjustment. This permits browse-only staff to inflate stock, reduce stock, or force out-of-stock states for variants outside the current page. This issue is fixed in version 2.9.2.","aliases":["GHSA-g3f9-g5vj-p62f"],"modified":"2026-09-16T03:47:07.260225690Z","published":"2026-09-15T17:40:01.302Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56829.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-862"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56829.json"},{"type":"FIX","url":"https://github.com/shopperlabs/shopper/commit/bf72e2753e21296184596d507336c7d65ecd46ff"},{"type":"FIX","url":"https://github.com/shopperlabs/shopper/pull/570"},{"type":"WEB","url":"https://github.com/shopperlabs/shopper/releases/tag/v2.9.2"},{"type":"ADVISORY","url":"https://github.com/shopperlabs/shopper/security/advisories/GHSA-g3f9-g5vj-p62f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-56829"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/shopperlabs/shopper","events":[{"introduced":"0"},{"fixed":"bf72e2753e21296184596d507336c7d65ecd46ff"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.9.2"}],"source":"AFFECTED_FIELD"}}],"versions":["v2.9.1","v2.9.0","v2.8.1","v2.8.0","v2.7.3","v2.7.2","v2.7.1","v2.7.0","v2.6.4","v2.6.3","v2.6.2","v2.6.1","v2.6.0","v2.5.0","v2.4.3","v2.4.2","v2.4.1","v2.4.0","v2.3.3","v2.3.2","v2.3.1","v2.3","v2.2.7","v2.2.6","v2.2.5","v2.2.4","v2.2.3","v2.2.2","v2.2.1","v2.2","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v2.0.0-beta21","v2.0.0-beta20","v2.0.0-beta19","v2.0.0-beta18","v2.0.0-beta17","v2.0.0-beta16","v2.0.0-beta15","v2.0.0-beta14","v2.0.0-beta13","v2.0.0-beta12","v2.0.0-beta11","v2.0.0-beta10","v2.0.0-beta9","v2.0.0-beta8","v2.0.0-beta7","v2.0.0-beta6","v2.0.0-beta5","v2.0.0-beta4","v2.0.0-beta3","v2.0.0-beta2","v2.0.0-beta","v1.1.2","v1.1.1","v1.1","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","V1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0","v0.0.26","v0.0.25","v0.0.24","v0.0.23","v0.0.22","v0.0.21","v0.0.20","v0.0.19","v0.0.18","v0.0.17","v0.0.16","v0.0.15","v0.0.14","v0.0.13","v0.0.12","v0.0.11","v0.0.10","v0.0.9","v0.0.8","v0.0.7","v0.0.6","v0.0.5","v0.0.4","v0.0.3","v0.0.2","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-56829.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H"}]}
