{"id":"CVE-2026-54612","state":"PUBLISHED","title":"Vvveb: Authenticated editor path traversal to PHP file write/RCE via data-v-save-global","description":"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.","publishedAt":"2026-09-17T21:46:27.346Z","updatedAt":"2026-09-18T20:04:55.345Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["givanz Vvveb"],"affected":[{"vendor":"givanz","product":"Vvveb","versions":[{"version":">= 1.0.0, < 1.0.8.5","status":"affected"}]}],"references":["https://github.com/givanz/Vvveb/security/advisories/GHSA-c3v9-3xrq-pvqv","https://github.com/givanz/Vvveb/commit/c8fef41ad8651d348050c513451755ab8882b97e","https://github.com/givanz/Vvveb/releases/tag/1.0.8.5"],"weaknesses":["CWE-22","CWE-94"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/54xxx/CVE-2026-54612.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-54612","state":"PUBLISHED","datePublished":"2026-09-17T21:46:27.346Z","dateUpdated":"2026-09-18T20:04:55.345Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-15T19:45:23.540Z"},"containers":{"cna":{"title":"Vvveb: Authenticated editor path traversal to PHP file write/RCE via data-v-save-global","descriptions":[{"lang":"en","value":"Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores.
