From 5.4.0 until 5.4.4 and 5.5.4, PATCH /api/v3/store/carts/:id/associate in Spree::Api::V3::Store::CartsController#associate uses find_cart_for_association to locate a cart by prefixed_id but does not require a cart token or otherwise verify possession of the selected guest cart. An authenticated customer can derive reversible prefixed cart IDs, associate an eligible guest cart with the attacker's account, and receive billing and shipping address data from the cart. Exploitation requires a guest cart with address data on a store that does not require login for checkout, and reassignment can also disrupt the guest's in-progress cart. This issue is fixed in versions 5.4.4 and 5.5.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","score":7.1},"cwes":["CWE-639"],"references":["https://github.com/spree/spree/commit/8834230a1f47bb5988f23f45dbd162776cf592bd","https://github.com/spree/spree/commit/af0d1a2d582a60d179de65b7d3ea024cb26426a8","https://github.com/spree/spree/pull/14314","https://github.com/spree/spree/releases/tag/v5.4.4","https://github.com/spree/spree/releases/tag/v5.5.4"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-94462","score":0.00384,"percentile":0.32476,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4825-p4xm-pcf2","url":"https://osv.dev/vulnerability/GHSA-4825-p4xm-pcf2","summary":"Spree: Broken Access Control in `PATCH /api/v3/store/carts/:id/associate` (IDOR)","modified":"2026-09-22T21:00:05.238442332Z","packages":[{"ecosystem":"RubyGems","name":"spree_api","purl":"pkg:gem/spree_api","ranges":[">=5.4.0 <5.4.4"],"fixed":["5.4.4"]},{"ecosystem":"RubyGems","name":"spree_api","purl":"pkg:gem/spree_api","ranges":[">=5.5.0 <5.5.4"],"fixed":["5.5.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
