{"id":"CVE-2026-73327","summary":"Joomla 6.1.1 Zip Slip Path Traversal via com_joomlaupdate extract.php","details":"Joomla 6.1.1 contains a path traversal vulnerability in the com_joomlaupdate extension that allows a Super User to be induced into extracting a crafted archive containing directory traversal sequences or absolute paths in ZIP entry filenames. Attackers can supply malicious ZIP entry names with parent-directory segments or absolute paths to the extract.php extraction routine, causing files to be written outside the intended destination root and enabling persistent remote code execution via planted PHP files.","modified":"2026-08-16T03:31:10.002638116Z","published":"2026-08-12T18:05:19.383Z","database_specific":{"cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73327.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73327.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73327"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/joomla-zip-slip-path-traversal-via-com-joomlaupdate-extract-php"},{"type":"FIX","url":"https://github.com/joomla/joomla-cms"},{"type":"FIX","url":"https://github.com/joomla/joomla-cms/commit/9678a171d37e1e10ca75c9124bdafe20fe14fa5b"},{"type":"FIX","url":"https://github.com/joomla/joomla-cms/pull/48057"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/joomla/joomla-cms","events":[{"introduced":"0"},{"fixed":"9678a171d37e1e10ca75c9124bdafe20fe14fa5b"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"6.1.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-73327.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:H/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H"}]}
