Prior to 0.31.2.0, the application fails to properly sanitize user-controlled input within System Settings – Company Information. Several administrative configuration fields accept attacker-controlled input that is stored server-side and later rendered without proper output encoding. These values are persisted in the database and rendered unsafely on public-facing pages only, such as the main landing page. There is no execution in the administrative dashboard—the vulnerability only impacts the public frontend. This vulnerability is fixed in 0.31.2.0.","published":"2026-04-06T16:49:10.176Z","modified":"2026-08-12T03:51:15.919177101Z","cvss":{"score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"ci4-cms-erp/ci4ms","fixedVersion":"0.31.2.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35035.json"},{"type":"ADVISORY","url":"https://github.com/ci4-cms-erp/ci4ms/security/advisories/GHSA-5ghq-42rg-769x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35035"},{"type":"PACKAGE","url":"https://github.com/ci4-cms-erp/ci4ms"},{"type":"WEB","url":"https://github.com/ci4-cms-erp/ci4ms/releases/tag/0.31.2.0"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:15.919177101Z"}}
