{"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":"2026-08-19T03:49:05.199954849Z","published":"2026-08-12T18:05:19.383Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73327.json"},"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"},{"last_affected":"bd77f0e215f7f4a17b0ddf78d39730b8abcac12a"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"6.1.1"}]}}],"versions":["6.1.1","6.1.1-rc1","6.1.0","6.1.0-rc3","6.1.0-rc2","6.1.0-rc1","6.1.0-beta3","6.1.0-beta2","6.1.0-beta1","6.1.0-alpha3","6.1.0-alpha2","6.1.0-alpha1","6.0.0-beta1","6.0.0-alpha3","6.0.0-alpha2","6.0.0-alpha1","5.1.0-alpha2","5.1.0-alpha1","5.0.0-rc","5.0.0-beta3","5.0.0-beta2","5.0.0-beta1","5.0.0-alpha4","5.0.0-alpha3","5.0.0-alpha2","5.0.0-alpha1","4.2.0-rc1","4.2.0-beta3","psr12final","psr12anchor","4.2.0-beta2","4.2.0-beta1","4.2.0-alpha3","cypress-io","cypress","4.2.0-alpha2","4.2.0-alpha1","4.1.0-rc1","4.1.0-beta3","4.1.0-beta2","4.1.0-beta1","4.1.0-alpha3","4.1.0-alpha2","4.1.0-alpha1","4.0.0-beta3","4.0.0-beta2","4.0.0-beta","4.0.0-alpha12","4.0.0-alpha11","4.0.0-alpha10","4.0.0-alpha9","4.0.0-alpha8","4.0.0-alpha7","4.0.0-alpha6","4.0.0-alpha5","4.0.0-alpha4","4.0.0-alpha2","4.0.0-alpha1","3.5.0-beta2","3.4.5","3.5.0-beta","3.4.4","3.4.4-rc2","3.4.4-rc","3.4.3","3.4.2","3.4.2-rc","3.4.1","3.4.1-rc2","3.4.1-rc","3.4.0","3.4.0-rc","3.4.0-beta3","3.4.0-beta2","3.4.0-beta1","3.2.4","3.3.0","3.2.3","3.2.2","3.2.1","3.2.0","3.1.5","3.2.0.rc","3.2.0.beta","3.2.0.alpha","3.1.1","3.0.3","3.1.0_beta5","3.1.0_beta4","3.1.0_beta3","3.1.0_beta2","3.1.0_beta1","3.0.1","3.0.0","3.0.0_beta1","3.0.0_alpha-2","3.0.0_alpha-1","2.5.6","2.5.5","2.5.4","2.5.1","2.5.0","2.5.0_beta2","2.5.0_beta1","1.7.3"],"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"}]}
