{"id":"CVE-2026-54612","summary":"Vvveb: Authenticated editor path traversal to PHP file write/RCE via data-v-save-global","details":"Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. From 1.0.0 until 1.0.8.5, saveGlobalElements() in admin/controller/editor/global-trait.php concatenates the attacker-controlled file portion of data-v-save-global to the active theme directory before loadHTMLFile() and file_put_contents() operate on it. An authenticated user with the default Editor role and editor/* permission can submit crafted HTML to module=editor/editor&action=save and traverse to an existing writable PHP file outside the theme directory. If the target is web-accessible, editor-controlled PHP content executes in the web server context; a shipped public/vadmin/index.php entrypoint can be used as an execution trampoline rather than requiring a test-only file. This can permit persistent webshell placement and compromise application confidentiality, integrity, and availability. This issue is fixed in version 1.0.8.5.","aliases":["GHSA-c3v9-3xrq-pvqv"],"modified":"2026-09-20T11:30:48.489576145Z","published":"2026-09-17T21:46:27.346Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22","CWE-94"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54612.json"},"references":[{"type":"WEB","url":"https://github.com/givanz/Vvveb/releases/tag/1.0.8.5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54612.json"},{"type":"ADVISORY","url":"https://github.com/givanz/Vvveb/security/advisories/GHSA-c3v9-3xrq-pvqv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54612"},{"type":"FIX","url":"https://github.com/givanz/Vvveb/commit/c8fef41ad8651d348050c513451755ab8882b97e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/givanz/vvveb","events":[{"introduced":"45b62b1662906b3e3e806915e5135dcbe17f741e"},{"fixed":"c8fef41ad8651d348050c513451755ab8882b97e"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"1.0.0"},{"fixed":"1.0.8.5"}]}}],"versions":["1.0.8.4","1.0.8.3","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-2026-54612.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
