{"id":"CVE-2026-34607","summary":"Emlog: Path Traversal in emUnZip() allows arbitrary file write leading to RCE","details":"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 $zip-\u003eextractTo($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.","aliases":["GHSA-2jg8-rmhm-xv9m"],"modified":"2026-07-08T08:12:51.737296367Z","published":"2026-04-03T22:35:56.664Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34607.json","cwe_ids":["CWE-22"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34607.json"},{"type":"ADVISORY","url":"https://github.com/emlog/emlog/security/advisories/GHSA-2jg8-rmhm-xv9m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34607"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/emlog/emlog","events":[{"introduced":"0"},{"last_affected":"4d2c2d1966c03a0d31a7040e51a260346d36a711"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"2.6.2"}],"cpe":"cpe:2.3:a:emlog:emlog:*:*:*:*:pro:*:*:*","source":["AFFECTED_FIELD","CPE_RANGE"]}}],"versions":["pro-2.6.2","pro-2.6.1","pro-2.6.0","pro-2.5.26","pro-2.5.25","pro-2.5.24","pro-2.5.23","pro-2.5.22","pro-2.5.21","pro-2.5.20","pro-1.0.0","pro-2.5.19","pro-2.5.18","pro-2.5.17","pro-2.5.16","pro-2.5.15","pro-2.5.14","pro-2.5.13","pro-2.5.12","pro-2.5.11","pro-2.5.10","pro-2.5.9","pro-2.5.8","pro-2.5.7","pro-2.5.6","pro-2.5.5","pro-2.5.4","pro-2.5.3","pro-2.5.2","pro-2.5.1","pro-2.4.3","pro-2.4.2","pro-2.4.1","pro-2.4.0","pro-2.3.18","pro-2.3.17","pro-2.3.16","pro-2.3.15","pro-2.3.14","pro-2.3.13","pro-2.3.12","pro-2.3.11","pro-2.3.10","pro-2.3.9","pro-2.3.8","pro-2.3.7","pro-2.3.6","pro-2.3.5","pro-2.3.4","pro-2.3.2","pro-2.3.1","pro-2.3.0","pro-2.2.11","pro-2.2.10","pro-2.2.9","pro-2.2.8","pro-test-02","pro-test-01","pro-2.2.7","pro-2.2.6","pro-2.2.5","pro-2.2.4","pro-2.2.3","pro-2.2.2","pro-2.2.1","pro-2.2.0","pro-2.1.15","pro-2.1.14","pro-2.1.13","pro-2.1.12","ci","pro-2.1.11","pro-2.1.10","pro-2.1.9","pro-2.1.8","pro-2.1.7","pro-2.1.6","pro-2.1.5","pro-2.1.4","pro-2.1.3","pro-2.1.2","pro-2.1.1","pro-2.1.0","pro-2.0.3","pro-2.0.2","pro-2.0.1","pro-2.0.0","pro-1.9.3","pro-1.9.2","pro-1.9.1","pro-1.9.0","pro-1.8.0","pro-1.7.1","pro-1.7.0","pro-1.6.0","pro-1.5.1","pro-1.5.0.new","pro-1.5.0","pro-1.4.0","pro-1.3.1","pro-1.3.0","pro-1.2.2","pro-1.2.1","pro-1.2.0","pro-1.1.1","pro-1.1.0","pro-1.0.8","pro-1.0.7","pro-1.0.6","pro-1.0.5","pro-1.0.4","pro-1.0.3","pro-1.0.2","pro-1.0.1","6.1.0","6.0.0","5.3.1","emlog_5.3.0","emlog_5.2.1","emlog_5.2.0","emlog_5.1.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-34607.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
