{"id":"CVE-2026-34607","state":"PUBLISHED","title":"Emlog: Path Traversal in emUnZip() allows arbitrary file write leading to RCE","description":"Emlog is an open source website building system. In versions 2.6.2 and prior, a path traversal vulnerability exists in the emUnZip() function (include/lib/common.php:793). When extracting ZIP archives (plugin/template uploads, backup imports), the function calls $zip->extractTo($path) without sanitizing ZIP entry names. An authenticated admin can upload a crafted ZIP containing entries with ../ sequences to write arbitrary files to the server filesystem, including PHP webshells, achieving Remote Code Execution (RCE). At time of publication, there are no publicly available patches.","publishedAt":"2026-04-03T22:35:56.664Z","updatedAt":"2026-04-06T15:42:13.270Z","severity":{"score":7.2,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["emlog emlog"],"affected":[{"vendor":"emlog","product":"emlog","versions":[{"version":"<= 2.6.2","status":"affected"}]}],"references":["https://github.com/emlog/emlog/security/advisories/GHSA-2jg8-rmhm-xv9m"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/34xxx/CVE-2026-34607.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-34607","state":"PUBLISHED","datePublished":"2026-04-03T22:35:56.664Z","dateUpdated":"2026-04-06T15:42:13.270Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-30T17:15:52.500Z"},"containers":{"cna":{"title":"Emlog: Path Traversal in emUnZip() allows arbitrary file write leading to RCE","descriptions":[{"lang":"en","value":"Emlog is an open source website building system.
