{"id":"CVE-2026-45622","summary":"Vvveb: Unauthenticated reflected XSS in public product return form via customer_order_id","details":"Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to 1.0.8.3, there is an unauthenticated reflected cross-site scripting (XSS) issue in the public product return form in Vvveb CMS. The customer_order_id POST parameter is inserted into the Order %s not found! error message when the order lookup fails, and that message is rendered in the frontend template without HTML escaping. As a result, attacker-controlled HTML/JavaScript executes in the submitting user's browser. This vulnerability is fixed in 1.0.8.3.","aliases":["GHSA-3xwm-8f6m-cfc6"],"modified":"2026-08-12T03:51:17.956801787Z","published":"2026-05-15T18:42:46.670Z","database_specific":{"cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45622.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45622.json"},{"type":"ADVISORY","url":"https://github.com/givanz/Vvveb/security/advisories/GHSA-3xwm-8f6m-cfc6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45622"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/givanz/vvveb","events":[{"introduced":"0"},{"fixed":"301e9b66a3b3a1cb42cb05ad1ff3cd428ed30b26"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.0.8.3"}],"source":"AFFECTED_FIELD"}}],"versions":["1.0.8.2","1.0.8.1","1.0.8","1.0.7.3","1.0.7.2","1.0.7.1","1.0.7","1.0.6","1.0.5","1.0.4","1.0.3","1.0.2","1.0.1","1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45622.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N"}]}
