Attackers can craft a zip archive with entry names containing \"..\" sequences, which PclZip's extract() processes without the PCLZIP_OPT_EXTRACT_DIR_RESTRICTION option, writing a PHP file outside the intended extraction directory into the web-servable tree to achieve remote code execution.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7.1,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:H/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":6.4,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1794486341651,"publishedAt":1794486341651,"references":[{"source":"CNA: VulnCheck","tags":["patch","release-notes"],"url":"https://wordpress.org/plugins/backup-backup/#developers"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/backup-migration-before-path-traversal-via-pclzip-restore-fallback"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
