{"id":"CVE-2026-100872","summary":"Sylius 2.x before 2.1.16 and 2.2.9 Payment Amount Overwrite","details":"Sylius versions before 2.1.16 and 2.2.9 fail to validate payment amounts during cart recalculation, allowing unauthenticated attackers to modify order totals after gateway transaction initiation. Attackers can pay a small amount, enlarge the order after gateway capture, and have the system mark the inflated order as fully paid while the gateway captured only the original amount.","aliases":["GHSA-vv4h-q2x8-74g4"],"modified":"2026-09-29T03:47:23.296783987Z","published":"2026-09-27T13:09:56.034Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100872.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-345"]},"references":[{"type":"WEB","url":"https://packagist.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100872.json"},{"type":"ADVISORY","url":"https://github.com/Sylius/Sylius/releases/tag/v2.2.9"},{"type":"ADVISORY","url":"https://github.com/Sylius/Sylius/security/advisories/GHSA-vv4h-q2x8-74g4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-100872"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/sylius-2-x-before-2.1.16-and-2.2.9-payment-amount-overwrite"},{"type":"FIX","url":"https://github.com/Sylius/Sylius/commit/9e9aeaacbc97b1fc01d573e44d6679194527905d"},{"type":"FIX","url":"https://github.com/Sylius/Sylius/pull/19216"},{"type":"PACKAGE","url":"https://github.com/Sylius/Sylius"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sylius/sylius","events":[{"introduced":"6dd3ca9895be7ab7e6cb71f37af2ef66af17cbe0"},{"fixed":"439a8f66dbf05f369337dc8358e2698d57aba663"},{"introduced":"7aa47be3a617f75337d73d245352ea700bc8a1ef"},{"fixed":"253169df80a8c8babf479c6de5ce3d422e37dc6a"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"2.0.0"},{"fixed":"2.1.16"},{"introduced":"2.2.0"},{"fixed":"2.2.9"}]}}],"versions":["v2.2.8","v2.2.7","v2.2.6","v2.1.15","v2.2.5","v2.1.14","v2.2.4","v2.1.13","v2.2.3","v2.1.12","v2.2.2","v2.1.11","v2.2.1","v2.1.10","v2.2.0","v2.1.9","v2.1.8","v2.1.7","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.3","v2.0.2","v2.0.1","v2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-100872.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
