{"id":"CVE-2026-34558","summary":"CI4MS: Methods Management Full Account Takeover for All-Roles & Privilege-Escalation via Stored DOM XSS","details":"CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. Prior to version 0.31.0.0, the application fails to properly sanitize user-controlled input within the Methods Management functionality when creating or managing application methods/pages. Multiple input fields accept attacker-controlled JavaScript payloads that are stored server-side without sanitization or output encoding. These stored values are later rendered directly into administrative interfaces and global navigation components without proper encoding, resulting in Stored DOM-Based Cross-Site Scripting (XSS). This issue has been patched in version 0.31.0.0.","aliases":["GHSA-v77r-xg3p-75g7"],"modified":"2026-04-10T05:43:03.677036Z","published":"2026-03-30T20:24:36.374Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34558.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34558.json"},{"type":"ADVISORY","url":"https://github.com/ci4-cms-erp/ci4ms/security/advisories/GHSA-v77r-xg3p-75g7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34558"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ci4-cms-erp/ci4ms","events":[{"introduced":"0"},{"fixed":"954622ef3d8527cde0b66b8460c26cb5cd0bab15"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"0.31.0.0"}]}}],"versions":["0.21.0","0.21.1","0.21.2","0.21.3","0.21.3.1","0.21.3.2","0.21.3.3","0.21.3.4","0.21.3.5","0.21.3.6","0.21.3.7","0.23.0.0","0.23.1.0","0.24.0.0","0.24.0.16","0.24.0.18","0.24.0.19","0.24.0.20","0.24.0.27","0.24.0.42","0.24.0.45","0.24.0.60","0.25.0.0","0.25.0.1","0.25.0.2","0.25.0.30","0.25.0.39","0.25.0.43","0.25.1.0","0.25.2.0","0.25.3.0","0.26.0.0","0.26.1.0","0.26.2.0","0.26.3.0","0.26.3.1","0.26.3.2","0.26.3.3","0.26.3.4","0.27.0.0","0.28.0.0","0.28.3.0","0.28.4.0","0.28.5.0","0.28.6.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-34558.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:L"}]}
